The secondary Converter in figure 1 with the primary unit, the conversion is identied in figure 2 operates as follows.

When submitting from the output of the source 5 harmonic or pulse signal in the positive half-cycle the current flows through the circuit: the first is the first clip of the source 5, the inductance 22, the diode 7, the parallel connected resistor 8 and the capacitor 10, the second clip channel 5; the second is the first clip of the source 5, the inductor 23, the diode 16, the parallel connected resistor 13 and the capacitor 14, the second clip channel 5; the third is the first clip of the source 5, an exemplary branch 17, the second clip channel 5; the fourth is the first clip of the source 5, the first output of the first dvukhpolosnykh exemplary branch 17 the second output of the first dvukhpolosnykh exemplary branch 17, the diode 18, the parallel connected resistor 19 and a capacitor 20, a second clip channel 5. In the negative half-cycle the current flows through three parallel circuits: first - second clip of the source 5, the diode 6, the inductance 22, the first clip channel 5; the second - second clip of the source 5, the diode 12, the inductor 23, the first clip channel 5; the third - second clip of the source 5, an exemplary branch 17, the first clip source 5. The resistors 8, 13, 19, respectively, are formed voltages V1, V2, V3 relatively common bus 11. The value of the first two voltages (V1, V2) depends on the position of the inductor 21 relative to the transducers provisions 22 and 23. The voltage V3 depends on the ratio of the elements of the standard branch 17, and does not depend on the position of the inductor 21 in the case when the source 5 is a voltage source, and a few depends on the position of the inductor 21 in the case when the source 5 is a current source. Constant voltages V1 and V2 are received at the first inputs, respectively, of the first 9 and 15 second comparator, the second input of which is supplied reference signal V3. In the initial state, as shown, for example, in Fig.6, the impedance of the transducer 22 position is approximately equal to the complex impedance of the transducer 23 as one conductive area of the inductor 21 is opposite the primary Converter 22, and the other in front of the transducer 23. This leads to the fact that V1=V2. Given that the third divider is selected so that in this position V1<V3 and V2<V3, information on outputs 3 and 4 of the secondary Converter at time to (figure 10) generates appropriate signals 1 and 1. When moving inductor 21 figure 6 to the right inductor occupies the position of figure 7. Thus at time t1(figure 10) impedance of the transducer 23 is reduced, resulting in V2>V3, whereas the impedance of the transducer 22 will not change. As a result of this VI and V3 will not change (in the case when the source 5 is the source voltage) or more will increase (in the case when channel 5 is a current source), but when V1<V3, which leads to the formation of information on outputs 3 and 4 secondary transducer signals 1 and 0, respectively. Upon further movement of the inductor 21 7 right inductor occupies a position on Fig. Thus at time t2(figure 10) impedance of the transducer 22 will decrease, resulting in V1>V3, whereas the impedance of the transducer 23 will not change. As a result of this voltage V2, and V3 will not change (if the source 5 is a voltage source) or more will decrease (if the source 5 is a current source), but V2>V3, which leads to the formation of information on outputs 3 and 4 secondary transducer signals 0 and 0 respectively. Upon further movement of the inductor 21 Fig right inductor occupies the position of figure 9. Thus at time t3(figure 10) impedance of the transducer 23 is additionally increased, resulting in V2<V3, and the impedance of the transducer 22 remains unchanged. As a result of this voltage V1 and V3 increase somewhat (if channel 5 is a current source) or not change (if the source 5 is a voltage source), but the inequality V1>V3 persists, h is about leads to the formation of information on outputs 3 and 4 secondary transducer signals 0 and 1, respectively. To determine the direction of movement it is necessary that the distance between the first 22 and second 23 primary converters meet one of the following conditions:

- if b≥then mod(a,(b+c))>b or mod(a,(b+c))<s, where mod(a,(b+c)) - modulo and (b+c); a is the distance between the first 22 and second 23 sensors; b - width of the conductive part of the inductor 21; width amagnitude section of the inductor 21.

- if b<C, mod(a,(b+c))>with or mod(a,(b+c))<b.

When moving the inductor 21 to the left (see consistently 6, 9, 8, 7, 6, 9) and return movement to the right (6, 7, 8, 9, 6, 7) you can define, as shown in Fig that between times t2and t3there has been a change of direction of the inductor 21, associated with the control object. When moving the inductor 21 to the left, the transition from 1 to 0 (Fig, t1) information on the output 4 of the secondary Converter occurs when the information output 3 of the secondary Converter is a signal of 0. Similarly, the transition in this condition from 1 to 0 (Fig, t2) information on the output 3 of the secondary Converter occurs when information on the output 4 of the secondary Converter the signal is present 1. When changing direction of movement of the inductor 21 is changed to the specified compliance. So the transition from 1 to 0 (Fig, t3 ) information on the output 3 of the secondary Converter occurs when information on the output 4 of the secondary Converter is a signal of 0. Similarly, the transition from 1 to 0 (Fig, t4) information on the output 4 of the secondary Converter occurs when the information output 3 of the secondary Converter the signal is present 1.

The secondary Converter in figure 1 with the unit transducers figure 3 operates as follows.

When submitting from the output of the source 5 harmonic or pulse signal in the positive half-cycle the current flows through the circuit: the first is the first clip of the source 5, the parallel connected primary winding 24 of the first 22 of the transducer position and the primary winding 26 of the second 23 of the transducer position, the second clamp source 5; second, the first terminal of the secondary winding 25 of the first primary Converter position 22, the diode 7, the parallel connected resistor 8 and the capacitor 10, the second terminal of the secondary winding 25 of the first primary Converter provisions 22; the third is the first clip of the source 5, an exemplary branch 17, the second clip channel 5; the fourth is the first clip of the source 5, the first clamp exemplary branch 17, the top of the exemplary branch 17, the diode 18, the parallel connected resistor 19 and a capacitor 20, a second clip channel 5;fifth, the first terminal of the secondary winding 27 of the second primary Converter position 23, the diode 16, the parallel connected resistor 13 and the capacitor 14, the second terminal of the secondary winding 27 of the second primary Converter provisions 23. In the negative half-cycle the current flows through the four parallel circuits: first - second clip of the source 5, the parallel connected primary winding 24 of the first 22 of the transducer position and the primary winding 26 of the second 23 of the transducer position, the first clamping channel 5; the second, the second terminal of the secondary winding 25 of the first primary Converter position 22, the diode 6, the first terminal of the secondary winding 25 of the first primary Converter provisions 22; the third - second clip of the source 5, an exemplary branch 17, the first clip channel 5; the fourth to the second terminal of the secondary winding 27 of the second primary Converter position 23, the diode 12 the first terminal of the secondary winding 27 of the second primary Converter provisions 23.

The resistors 8, 13, 19, respectively, are formed in the constant voltage V1, V2, V3 relatively common bus 11. The value of the first two voltages (V1, V2) depends on the position of the inductor 21 relative to the transducers provisions 22 and 23. The voltage value V3 depends on the ratio of parameters of elements of an exemplary branch 17, and from the position the of the inductor 21 is not affected. The voltages V1 and V2 are received at the first inputs, respectively, of the first 9 and 15 second comparator, the second input of which is supplied reference signal V3. In the initial state, as shown, for example, in Fig.6, the voltage taken from a secondary winding 25 of the transducer 22 position, approximately equal to the voltage taken from a secondary winding 27 of the transducer 23 as the opposite of both transducers 22 and 23 of the Statute conductive area of the inductor 21. This leads to the fact that V1=V2. Given that the elements of the exemplary branches are chosen so that in this position V1>V3 and V2>V3, information on outputs 3 and 4 of the secondary Converter at time t0(11) are formed signals 0 and respectively. When moving inductor 21 figure 6 to the right at time t1(11) the inductor occupies the position of figure 7. This secondary voltage primary transformer 23 will decrease and V2<V3, whereas the secondary voltage primary transformer 22 will increase (in the case where the signal source 5 is a current source) or not changed (when the signal source 5 is a voltage source), which leads to the formation of information on outputs 3 and 4 secondary transducer signals 0 and 1, respectively. Further PE is Emesene inductor 21 figure 7 to the right at time t 2(11) the inductor occupies a position on Fig. This secondary voltage primary transformer 22 will decrease, which leads to the formation of information on outputs 3 and 4 secondary signal transducer 1 and 1, respectively. When further moving inductor on Fig to the right at time t3(11) the inductor occupies the position of figure 9. This secondary voltage primary transformer 23 is additionally increased, and the primary Converter 22 remains unchanged (in the case where the signal source 5 is a voltage source) or decreases (in the case where the signal source 5 is a current source), which leads to the formation of information on outputs 3 and 4 secondary transducer signals 1 and 0, respectively.

The secondary Converter in figure 1 with the unit transducers figure 4 operates as follows.

When submitting from the output of the source 5 harmonic or pulse signal in the positive half-cycle the current flows through the circuit: the first - the first clip source 5, connected in series the primary winding 24 of the first 22 of the transducer position and the primary winding 26 of the second 23 of the transducer position, the second clamp source 5; second, the first terminal of the secondary winding 25 of the first primary pre is brazaletes position 22, the diode 7, the parallel connected resistor 8 and the capacitor 10, the second terminal of the secondary winding 25 of the first primary Converter provisions 22; the third, the first terminal of the secondary winding 27 of the second primary Converter position 23, the diode 16, the parallel connected resistor 13 and the capacitor 14, the second terminal of the secondary winding 27 of the second primary Converter provisions 23; the fourth is the first clip of the source 5, an exemplary branch 17, the second clip channel 5; the fifth is the first clip of the source 5, the first clamp exemplary branch 17, the top of the exemplary branch 17, the diode 18, the parallel connected resistor 19 and the capacitor 20, the parallel connected resistor 19 and a capacitor 20, a second clip channel 5. In the negative half-cycle the current flows through the four parallel circuits: first - second clip of the source 5, connected in series the primary winding 24 of the first 22 of the transducer position and the primary winding 26 of the second 23 of the transducer position, the first clamping channel 5; the second terminal of the secondary winding 25 of the first primary Converter position 22, the diode 6, the first terminal of the secondary winding 25 of the first primary Converter provisions 22; the third, the second terminal of the secondary winding 27 of the second primary Converter position 23, the diode 12, the first terminal of the secondary winding 27 of the second pervi the aqueous transducer position 23; fourth - second clip of the source 5, an exemplary branch 17, the first clip source 5. The resistors 8, 13, 19, respectively, are formed in the constant voltage V1, V2, V3 relatively common bus 11. The value of the first two voltages (V1, V2) depends on the position of the inductor 21 relative to the transducers provisions 22 and 23. The voltage value V3 depends on the ratio of parameters of elements of an exemplary branch 17, and the position of the inductor 21 is not affected. The voltages V1 and V2 are received at the first inputs, respectively, of the first 9 and 15 second comparator, the second input of which is supplied reference signal V3.

In the initial state, as shown, for example, in Fig.6, the voltage taken from a secondary winding 25 of the transducer 22 position, approximately equal to the voltage taken from a secondary winding 27 of the transducer 23 as the opposite of both transducers 22 and 23 of the Statute conductive area of the inductor 21. This leads to the fact that V1=V2. Given that the elements of the exemplary branches are chosen so that in this position V1>V3 and V2>V3, information on outputs 3 and 4 of the secondary Converter at time t0(11) are formed signals 0 and 0 respectively. When moving inductor 21 figure 6 to the right at time t1(11) the inductor is agenie 7. This secondary voltage primary transformer 23 will decrease and V2<V3, whereas the secondary voltage primary transformer 22 will increase (in the case where the signal source 5 is a voltage source) or not changed (when the signal source 5 is a current source), which leads to the formation of information on outputs 3 and 4 secondary transducer signals 0 and 1, respectively. Upon further movement of the inductor 21 figure 7 to the right at time t2(11) the inductor occupies a position on Fig. This secondary voltage primary transformer 22 will decrease, which leads to the formation of information on outputs 3 and 4 secondary signal transducer 1 and 1, respectively. When further moving inductor on Fig to the right at time t3(11) the inductor occupies the position of figure 9. This secondary voltage primary transformer 23 is additionally increased, and the primary Converter 22 remains unchanged (in the case where the signal source 5 is a current source) or decreases (in the case where the signal source 5 is a voltage source), which leads to the formation of information on outputs 3 and 4 secondary transducer signals 1 and 0, respectively.
