In addition, the invention relates to high-voltage input node of a high pressure for use in an input device defined in the restrictive parts of paragraphs 27 and 30 of the claims.

For stable supply and to increase the supply of hydrocarbon technological environment such as gas condensate gas or fluid from the production well, located under the water to land or surface, usually downstream from the site of rough cleaning liquid set air compressor or pump. For compressor or pump is required to drive the motor with high wattage, usually working in the 500-2000 range of currents and voltages 6.6-12 kV AC. In addition, when moving hydrocarbon fluids over large distances on the earth's surface to ensure the stability of the stream regardless of the complexity of the landscape usually requires installation at equal intervals auxiliary compressors or pumps.

Fluid which is used for cooling of the motor is as wet as it can contain water and contaminated, because it usually contains conductive particles and a large number of other various contaminants that can cause arc discharge, leakage current and voltage drop. In the worst case, this operation may cause ignition of gas and explosion with catastrophic consequences.

In addition, for example, in the extraction of gas condensate may occur a sharp drop in pressure, resulting in devices such as o-rings and electroisolator, under high pressure can simply be broken, which can lead to the danger of permanent damage to the compressor or pump subsea installation.

Detailed description of the invention

The figure 1 shows a non-limiting example of typical operating conditions conductive unit 1, to which the surface 3' of the sea 3 are the power and signal cables 2 cables 2', power cables 2 are powered from the generator 15' offshore installation, such as an offshore platform 15 (for simplicity not shown in scale relative to the compressor unit 4, 5, 6 on the seabed 8). Signal cables 2' go to install 15" signal processing at the facility 15. The power from the power cables 2 is transmitted through the node 1' unit 1, and the power cables 2 go from node G through the inner portion 1' of the unit down to the connecting terminals 4' inside 4" motor 4, the configuration of which provides the drive is installed upstream of the compressor or pump 5 wet fluid and downstream of the compressor or pump 6 wet fluid.

The compressor or pump 5 captures the fluid, for example, gas 7' of the collector 7 beneath the seabed 8, and the fluid passes through the separator 9, which releases the fluid from the condensate, such as gas condensate 10, and transmits the fluid, for example gas 11, which can still be described as a moist fluid through the pipe 12 into the first compressor or n is SOS 5. From the compressor 5 compressed or pumped fluid passes through the cooling channels 4'" in the electric motor 4, and then moves on through the second compressor or pump 6 and thence in the form of fluid 13 under pressure, for example, gas back into the reservoir 7', for example, through the throttle valve 14 and line 14'. As soon as the pressure in the reservoir reaches a sufficient magnitude, the dispenser 14 may be submitted to the team with the installation of 15 to redirect the output stream from the compressor 6 to the side surface through the tubing 14". Under certain conditions the pressure in the reservoir may be high enough to ensure that there is enough straight pipe downward into the reservoir.

As indicated in the introductory part, the motor 4 is a motor of high power, and therefore it is necessary that the conductive unit was able to withstand the corresponding large currents and voltages, as well as high values of temperature and pressure, and, in addition, was able to issue a warning when danger is inevitable emergencies at work, requiring immediate shutdown of the compressor or pump unit 4, 5, 6.

As shown in figure 1, it is important that conductive unit 1 is supported vertically by attaching to the chassis nm is the engine 4" compressor unit 4, 5, 6 for subsea wet gas.

The following is a brief description of embodiments of the invention shown in figure 1, with reference to figures 5 and 6 illustrate how the present invention can be used not only located on the surface of wells for the production of hydrocarbon fluids.

Figure 5 shows another non-limiting example of typical operating conditions conductive unit 51, where power cables 52 and signal cables 52' go from installation 53. Power cables 52 are powered from the generator 53' ground installation, such as platform 15 (for simplicity not shown in scale relative to the compressor or pump Assembly 54, 55, 56). Signal cables 52' go to install 53" signal processing on the unit 53. The power from the power cable 52 is passed through the conductive node 51' unit 51, and the power cables 52" go from conductive node 51' through the inner portion 51" of the unit down to the connecting terminals 54' inside 54" motor 54, the configuration which provides the drive is installed upstream of the compressor or pump 55 oil fluid and installed downstream of the compressor or pump 56 fluid environment.

The compressor captures the fluid 57' of the manifold 57 below ground level, and the fluid passes through separ the tor 58, which releases fluid from the condensate 58' and passes the fluid 58, which can still be described as a moist fluid, through conduit 58'" in the first compressor or pump 55. From the compressor or pump 55, the compressed fluid passes through the cooling channels 54'to the motor 54, and then moves on through the second compressor or pump 56 and thence in the form of compressed fluid 59' back into the tank 57', for example, through a throttle valve 59 and line 59'. As soon as the pressure in the reservoir will increase to a sufficient magnitude, with the installation of 53 on the valve 59 may be remotely submitted command to redirect the output stream from the compressor or pump 56 in the direction of installation 53 through the valve 59 and line 14"'. Under certain conditions the pressure in the reservoir may be high enough to ensure that there is enough straight pipe downward into the tank.

As indicated in the introductory part, the motor 54 will be an electric motor great power, and therefore it is necessary that the conductive unit was able to withstand the corresponding large currents and voltages, as well as high values of temperature and pressure, and, in addition, was able to issue a warning when the danger of the unknown is panorama emergencies at work, requiring immediate shutdown of the compressor or pump unit 54-56.

As shown in figure 1, it is important that the same way as in the embodiment of the invention shown in figure 5, the conductive unit 51 is supported vertically by attaching to the motor frame 54" compressor or pump unit 54-56.

The figure 6 shows another non-limiting example of typical operating conditions conductive unit 61, where power cables 62 and signal cables 62' go from platform or management station 63, power cables 62 are powered from the generator 63' platform or management station 63 (for simplicity not shown in scale relative to the compressor or pump unit 64-66). Signal cables 62' go to install 63" signal processing at the facility or station 63. The power from the power cables 62 is passed through the conductive node 61' unit 61, and the power cables 62" go from conductive node 61' through the inner part 61" unit down to the connecting terminals 64' inside 64" motor 64, the configuration which drives the compressor or pump 65 for the oil fluid, installed upstream, and a compressor or a pump 66 for oil fluid, installed downstream.

The compressor 65 through line 67 sucks the fluid is set to the first flow rate, and to maintain or increase this flow front on the go from a compressor or a pump 66, the pipe 68, the fluid from the pipeline 67 enters the first compressor or pump 65. From the compressor 65 compressed fluid passes through the cooling channels 64'" in the motor 64, and then moves on through the second compressor or pump 66 and thence in the form of compressed fluid enters located in the front along the pipeline with preserved or increased hydraulic pressure and, consequently, improved consumption. As indicated in the introductory part, the motor 64 should be a motor of high power, and therefore it is necessary that the input device was capable of withstanding the appropriate large currents and voltages, as well as high values of temperature and pressure, and, in addition, was able to issue a warning when danger is inevitable emergencies at work, requiring immediate shutdown of the compressor or pump unit 64-66.

Figure 7 shows a modification of a variant embodiment of the invention shown in figure 6, which is another non-limiting example of typical operating conditions input devices 72, working in conjunction with the compressor unit 71 and the power cables 73 coming from the supply lines 74. The compressor is and has a pipeline 75 for supplying hydrocarbon fluid in the compressor unit 71 and the pipe 76 to exit of fluid from the unit. The hydrocarbon fluid may be a gas condensate. Such compressor units are especially useful when moving a fluid medium on the basis of hydrocarbons over long distances, for example, from Siberia to Europe to increase the pressure to compensate for pressure losses caused by leaks or simply large distances.

The figure 8 shows the application of the present invention for supplying, for example, power supply to subsea compressor or pump, conventionally denoted by the numeral 80. The power supply may, for example, have a nominal voltage of 6 kV AC, while the electric power transmitted from located on the surface of the site, such as a floating platform 89, may have a nominal voltage of 12 kV AC. It is clear that, if necessary, transfer the power to the compressor or pump, located under water for a safe transfer of power to such compressor or pump may be used in the input device described with reference to figures 1-7. In the embodiment of the invention shown in figure 8, shows the transformer 81 to the primary winding 82 and a secondary winding 84 and an additional selection 83 power from the transformer to drive the circulation pump 85, intended for cooling transformate is as oil or gas. As a cooling gas can be used SF6. Power to the primary winding 82 is supplied from a located on the surface of section 89 on power cables 88 through the device 86 input. Power from the secondary winding is supplied to the compressor or pump 80 via the input device 87 and power cables 87'. It is also possible presence of signal cables connected with the appropriate cables 87' and 88. Although the transformer 81, for simplicity, shows a single-phase, to a person skilled in the art will understand that in reality, the transformer is a transformer for converting three-phase current three-phase current.

Figure 9 shows another application of the present invention when it is used, for example, together with the gushing wellhead 91 used in the subsea pipeline systems, and, for example, for use with a downhole pump or compressor 93, host of hydrocarbon fluid through the pipe 94 and the feed after raising the pressure of the fluid on the basis of hydrocarbons to the wellhead through the exhaust pipe 92. Although it was specified node x-Mas tree can be provided by the application and other nodes of the distribution of the fluid. For safe power supply and even the transmission of signals through cables input device 94 and 96 provided associated with westwoodone power cables 95 and 97. The input devices may be provided for the signal line, which can be included in the internal part of the braid power cables. Although shown two input devices 94, 96 for the respective cables may require only one of them.

As shown in figures 1 and 5, in the context of embodiments of the invention shown in figures 6, 7-9, it is important that the input device 61; 72; 86; 87; 94; 96 vertically after attaching to one of the following elements: housing 64" motor unit 64-66, compressor unit 71, the transformer 81 and the compressor or pump 93.

The following is a description of an input device with reference to figures 2 and 3.

As shown in figures 2 and 3, the device comprises an input node 16 for flow through him power to the electric motor 4 of the compressor, and the node 16 in a specific non-limiting embodiment, comprises a total of six input elements 17-22 for power supply and the input element 23 connected to the measuring unit 24. Each input element has 17-22 support and the cable holder, designated 17' and 22'attached to the ceramic base plate 17"; 20, respectively. The measuring unit 24 is connected with the tool 15"; 53"; 63" signal processing, located on the installation 15; 53; 63. Detailed description of the operation of the measuring unit is the who.

In addition, the input device has a funnel-shaped housing 25 with the box-shaped chamber 25', and the input node 16 is located at the upper end of the chamber 25'.

The grid 26 is located inside the chamber transversely relative to the longitudinal axis 27 of the camera, and the input node 16 is located above the grid 26. The mesh preferably has a middle portion 26'which is impervious to liquid or gas, i.e. where there are no holes. The purpose of this secondary plot - improvement of flow parameters inside the chamber 25' and the deviation of the bottom stream from the sensor 24.

The filter 28 is located in the chamber 25' below the grid, above the entrance hole in the casing 4"; 54"; 64" motor 4; 54; 64 compressor or pump. The filter 28 may be formed by a mass of ceramic granules, washers, tubes or beads, although it is also allowed to use other materials and forms, providing essentially equivalent to the operation of the filter.

As mentioned above, the input device also includes a measuring unit 24, which leads from the node input 16 into the chamber 25' to the grid 26, remaining from her at some distance, as seen in figure 2. The measuring unit 24 is configured to communicate with the specified tool 15" signal processing, external input devices via one or more signal cable 2'. The measuring unit may Ametsreiter for monitoring environmental parameters 29 inside the housing 25, while this tool may be one of the following devices: pressure sensor 24, the temperature sensor 24, the sensor 24"' of the level of liquid gas and the gauge 24"" to determine the type or types of fluid inside the chamber. Valid, but not necessarily to the measuring unit contained all four types of sensors. Although the sensors may be located on the site of entry on individual supports (not shown), the preferred embodiment of the invention is one in which all the sensors are placed on the shared host device 30, which passes into the chamber 25' in the gap between the input node 16 and the grid 26.

Thus, the input node 16 with the input items 17-23, located above the chamber 25', as shown in figures 1, 5, or 6, hermetically closed chamber 25'. In the embodiment of the invention shown in figure 1, the input node 16 is cooled directly by sea water 3. The motor, as well as compressors or pumps, as the body 25 and, therefore, the internal volume of 25' hull certainly somewhat cooled the surrounding seawater. In embodiments of the invention, shown in figures 5 and 6, to provide sufficient cooling may require the use of special cooling units (not shown)located around the elements of the water and compressor or pump units. In regions where the temperature is very low throughout most of the year or during significant periods of the year, year-round artificial cooling by means of cooling units is not necessary. When the availability of water from nearby wells or rivers this water as needed can be used for additional artificial cooling.

In the structure there is provided a sealing ring 45 and the retaining ring 46. Figures 47 and 48 indicated the insulation of the cable on the input cable 2; 52; 62 and the output cable 2"; 52"; 62".

Rather it is important that the input device was mounted so that the longitudinal axis 27 of the node 16 and the funnel-shaped housing 25 was located essentially vertically, preferably possible was vertical. In this connection it is necessary to take measures for proper placement on the seabed 8 compressor or pump unit 4, 5, 6, to allow such vertical arrangement. In addition, for ground installation, such as schematically shown in figures 5 and 6, this vertical arrangement is required. This aspect is important to first in the camera did not get fluid. Fluid, such as gas condensate, which is pumped and faces KAB is whether inside the motor, due to the high pressure will be faced with the cables from the inside or from the high pressure chamber 25'. This area is a dead-end section of the chamber with high pressure on this part of the circulation of the fluid based on hydrocarbons, for example, gas condensate is absent or negligible.

The filter 28, for example, of ceramic granules works as a filter intercepting any electrically conductive particles transported fluid medium, for example, condensate gas, and also works as a flame arrester in the event of an explosion in the motor.

To avoid decompression explosion of organic materials are usually subjected to high pressures, such as, for example, the material of the sealing rings, washers or electrical insulation, it should be possible to avoid the use of organic materials. Thus, it is preferable to limit the use of organic materials only materials of the cable insulation. All other materials input elements operating at high voltages, and the input node is made of one or more of the respective glass materials, ceramic materials and ceramic materials. In addition, the insulation can be applied silicone materials.

Because the connection between the element CC is Yes, for example, the input element 17, and the cable, for example cable 2"; 52"; 62", is an "open" design, i.e. is provided only with the help of ceramic deflecting device and a distance to leakage of electric current on the surface, it is important to prevent entry of fluid in liquid form in contact with any conductive part of this section of the input device.

In non-limiting variant, shown in figure 1, when filling out the motor 4 and its body 4" due to functional failure fluid such as sea water and/or gas condensate, at the level of the seabed and running the motor, the prevailing pressure will displace the liquid in the upper part of the motor. Consequently, fluid in the form of gas inside the chamber will be compressed due to the rise of liquid level in the chamber 25'. Volume of the chamber 25' is preferably about ten times the volume necessary to maintain the input elements 17-22 in the dry state. Thus, pressure 29 inside the chamber 25' may increase 10 times before the liquid level reaches a state of equilibrium with the compressed gas inside the chamber.

However, when the level of liquid to a potentially critical value trigger sensors 24'and 24", resulting in the issuance of the alarm, calling the th suspend work until it reaches a more normal pressure parameters.

The sensors 24', 24"' and 24"may be a capacitance-type sensors, although it is also possible to envisage the use of sensors for measuring pressure, fluid level and fluid properties. The sensor 24" temperature may be a sensor of the standard type.

It is important that the measuring unit has determined the occurrence of excessive temperatures that may lead to thermal breakdown, or raising the liquid level inside the chamber 25' above the critical operating values.

It should be noted that the input elements may have a configuration in General is shown in figure 2, or a configuration in more detail is shown in figure 4.

Considering the fact that the compressor or pump unit with inlet node in some embodiments, the application may be placed on the seabed at a significant depth, for example, at a depth of 250 m, it is considered that the pressure at this depth is 25 bar.

As shown in figure 1, the motor 4 compressor or pump unit 4, 5, 6 may be tested at a pressure of, for example 440 bar, while the operating pressure is usually not more than, for example, 220 bar. It is important to note that the fluid medium, for example, the gas supplied from the compressor or pump 5 circulates around the windings of the electric motor 4 when the discharge pressure of the compressor 5. Similar levels of pressure can be applied to var the ants embodiment of the invention, shown in figures 5 and 6, although the operating pressure can be lower.

Before lowering the compressor unit on the seabed, it is preferable to fill the motor with gas, having a pressure exceeding the external pressure on the seabed, for example, in this embodiment a pressure of 30 bar, which also is the initial pressure in the chamber 25'.

Figures 30 and 29 in figure 4 marked and defined part of the input element, which is exposed to the surrounding marine environment 3 and which are exposed to the environment inside the housing 25, respectively. Thus, the position 30 in the context of figures 5 and 6 may relate to the surrounding air or refrigerant.

In a possible modification of such fluid medium, as condensate gas inside the chamber may be provided with heating elements for drying gas or condensation condensate gas inside the chamber or removal of wet gas from the chamber.

As indicated above, to ensure the safe operation of the device it is important that each high voltage input 17-22 at the input node 16 was able to withstand occur during operation of the electric load, as well as conditions of temperature and pressure. Typical, but non-limiting variant of the invention, the high voltage of the input element is shown in figure 4. Item BB is Yes contains the terminal 31 of the input cable and the output terminal 32 of the cable, conductive pin 33, is covered on both sides and passing between the terminals 31 and 32 adapted to connect these ends to the input cable 2 and the output cable 2", respectively, using accurate contact landing. Ceramic sleeve 34, 35 surrounds the corresponding terminals 31, 32 and the adjacent parts of the conductive pin 33 and the cable 2; 2". The insulator is designed in such a way that it surrounds at least a substantial area of a conductive pin 33. The insulator may include a housing 36 of the protective cap with silicone oil or gel 37 surrounding the input terminal 31; ceramic deflecting device 38 and the insulator barrier 39 pressure from glass, ceramic, or glass-ceramic material. In addition, the housing 36 of the protective cap is in contact with the sleeve 40 of the fastening element input. The device 41 of the cable seal is installed on the sleeve 40 and goes to the side of the input element, which includes the cable. The device 41 of the cable seal provides internal clearance 42'adjacent to the input side of the housing 36 of the protective cap, with a specified internal clearance filled with silicone oil or gel 42'.

The metal housing may be made of titanium material, for example, titanium group 5. However, instead it can be applied to titanium alloys or other suitable materials with performance characteristics similar to the characteristics of titanium when working in the prevailing conditions. In addition, to obtain the maximum distance to leak electric current on the surface, at least part of the metal housing with the inner side of the cover glass, ceramic or glass-ceramic material 44, and the material is in contact with at least part of the ceramic deflecting device 38, and the metal housing 38 has a plot 43' funnel shape from the output terminal 32 of the input element.

A modified version of the implementation of the input device shown in figure 10, works on the same principles as variant, shown in figure 2. However, in this modified variant simpler in some aspects of the design, in particular, from the point of view of manufacturing the input device. It has the same or similar scope, as shown in figure 2. This modified device is in the input or the node 100 is applied, as the input device, shown and described above with reference to figures 1 and 5-9, and has the same General description, not requiring repetition.

As shown in figures 1 and 5-9, it is important that the modified input device 100 is supported vertically after connecting, for example, to the housing 64" motor unit 64-66, compressor unit 71, transformer 81 and the compressor or pump 93, respectively.

The following is a description of an input device with reference to figure 10.

As shown in figure 10, the device comprises a funnel-shaped housing 101. Plate or sleeve 102 of the input element is hermetically attached to the top of the neck of the housing 101, for example, by means of bolted or welded connections.

High-voltage pins 103 input, designed for high currents, as well as the input 104 of the cable pass through plate or sleeve 102 of the input element. The input 104 provides a connection to the measuring unit 105, which has the same type as the unit 24 described with reference to figure 2. The pins 103 and the input 104 is hermetically attached to the plate or sleeve 102 of the input element using a glass material, a ceramic material or a ceramic material 106. Compared to the embodiment of the invention shown in figure 2, which has a more complex structure of conductive mounting pins, crepe is a group of pins 103 and input 104 directly to the plate or sleeve 102 of the input element allows you to get considerably simplified, cost-effective and at the same time reliable input device. The measuring unit 105 is located in the chamber 107 and the grid 108 separates the chamber 107 from section 110 filter and also serves as a support for cables 109. Cable configuration 109 provides transmission of power, for example, for a motor of a compressor or a pump or other equipment, as well as to the transformer and from the transformer. The input 104 may contain a metal tube, for example, of titanium or titanium alloy or stainless steel, through which the signal conductors, for example, embedded in an insulating material such as glass, ceramic or glass-ceramic material.

In the lower part of the section 110 filter is a perforated plate 111, which may be made of a ceramic material, and through which can pass the cables 109. The holes in the grid 108, and the plate 111 are sufficiently small to prevent passage of the filter material through the mesh 108 and/or the plate 11. In is shown in the figure 10 example shows only two cables 109, connected to the cables 112 through the pins 103. However, it should be understood that it is possible to use more than two cables 109, two cables 112 and the connecting pins 103. Thus, these structural elements may be, for example, three, four, five sludge is six, and in some cases even more.

The following is a brief description of other details of the operation of the measuring unit.

It should be noted that the plate or sleeve 102, which are mounted pins 103 and the input 104, located on the upper end of the chamber 107.

The grid 108 is located inside the chamber 107 transversely relative to the longitudinal axis of the chamber. The grid in the middle part to be impervious to liquid or gas, for example, have no holes. The middle part is used for improving the characteristics of the flow inside the chamber 107 and the deviation of the bottom stream from the sensor 105.

The filter 110 is located in the chamber 107 under the grid 108, above the entrance opening in the housing of the compressor, motor, pump, transformer, or other work unit. The filter 110 may be formed from a mass of ceramic granules, washers, tubes or bulbs, although you can also use other materials and elements of other shapes, provided that they provide essentially equivalent performance characteristics.

As mentioned above, the input device also includes a measuring unit 105 and attached to the input 104. The measuring unit 105 is inside the chamber 107 from the site location plate or sleeve 102 of the input element to the grid 108. The measuring unit 105 is located at some distance from the grid 108, and in some case the s may be located near the grid or lightly touch her. The configuration of the measuring unit 105 provides its interaction with the specified means of signal processing such as described above, the tool 15", located on the outside of the device via one or more signal cables 113. The measuring unit 105 is an appropriate means of controlling the properties of the medium inside the housing 101, the tool 105' may be one of the following: pressure sensor, temperature sensor, level sensor, liquid and gas control sensor type or types of fluid inside the chamber. Valid, but not necessarily to the measuring unit contained all four types of sensors. Although the sensors may be located on the site of entry on individual supports (not shown), the preferred embodiment of the invention is one in which all the sensors are located on a shared host device 105', which takes place inside the chamber 107, the gap between the plate or sleeve 102 conductive device and a network 108.

Node input pins 103 and input 104 is mounted on top of the camera 107, hermetically closing, thus, the camera 107. Cooling input devices depends on the environment in which it operates. The description of this question above and will not be repeated.

The sealing ring 114 may be required or may not be required, hung is on the way of fixing a plate or sleeve 102 to the funnel 101. The insulation of the cables 112 are indicated by position 115, and the insulation is made in the form of protective caps. Protective caps filled with an appropriate silicone oil or gel. The caps are located inside the housing 116 of the protective caps. Made protective outer casing or shroud 117 is filled with silicone fluid medium such as silicone oil or gel 118.

The bottom end of the funnel 101 is supplied with a corresponding mounting flange 101' for fastening, for example, to the motor housing, pump housing, the housing of the transformer or the body of another functional unit. The flange 101' has a recess for accommodating the o-ring or other sealing means.

As mentioned above, it is quite important that the input device was installed so that its longitudinal axis located essentially vertically, preferably upright as possible. Therefore, you should take measures to ensure that, for example, a compressor or pump unit, to which is attached the device was placed in such a way as to provide a similar vertical installation. This aspect is important in the sense that first, no fluid will not enter the cell. Fluid, such as gas condensate, which flows and is faced with the cables inside electrodes the body, due to the high pressure will be faced with the cables from the inside or from the side with the high pressure chamber 107. This area of the camera is a dead-end area with high pressure, in which the circulation of the fluid based on hydrocarbons, for example, gas condensate is absent or negligible.

The filter 110, for example, of ceramic granules works as a filter intercepting any electrically conductive particles transported fluid medium, for example, condensate gas, and also works as a flame arrester in the event of an explosion, for example, in the motor.

As stated above, to avoid decompression explosion of organic materials are usually subjected to high pressures, such as, for example, the material of the sealing rings, washers or electrical insulation, it should be possible to avoid the use of organic materials. In this modified embodiment, the input device effectively reduced the risk of such situations, because the use of organic materials is kept to an absolute minimum, i.e. the use of organic materials is limited by the insulation of the cables. All other material details of the input elements operating at high voltages, and the input node is made of one or more approach is the yaschih glass materials, ceramic materials and ceramic materials. In addition, the insulation can be applied silicone materials.

Because the connection between the input element, for example a pin 103, and a cable, for example cable 109 is an "open" design, it is important to prevent entry of fluid in liquid form in contact with any conductive element in this part of the input device. The area of contact between the pin 103 and the cable 109 may be surrounded by a ceramic sleeve 119.

Aspects of functioning, environment, and properties and characteristics of input devices, as described with reference to figures 1 and 5-9, equally suitable for a modified input device, shown in figure 10, therefore repeated explanation of its operation is not described. Thus, the description of the functioning and properties, see, for example, the measuring unit 24, the same description for the measuring unit 105.

It should be noted that the construction described with reference to figure 4, is not present in the embodiment of the invention shown in figure 10, which makes the construction shown in figure 10, a simplified version of the input devices.

As indicated above, a funnel-shaped housing 101 is made of the corresponding titanium material or alloy, or steel. The corresponding titanium is the material can be a, for example, the titanium group 5. As for steel, it is preferable to use stainless steel. However, instead of these materials can be used, and other suitable materials having at work in the prevailing operating conditions operating properties similar to those of titanium. The same materials can also be applied to plate 102 and the housing or casing 117, and other metal items used in the input device.
