The secondary Converter in figure 1 with the unit transducers in figure 2 and the inductor unit transducers figure 5 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 first winding 24 of the transducer position, the voltage divider 15, the common bus 10, the second clip channel 5; the second is the first clip of the source 5, the first winding 24 of the transducer position, the diode 6, the parallel connected capacitor 8 and the resistor 9, the common bus 10, the second clip channel 5; the third is the first clip of the source 5, the first winding 24 of the transducer position, the first clamp voltage divider 15, the top the voltage divider 15, a diode 16, the parallel connected capacitor 17 and resistor 18, the common bus 10, the second clip channel 5; the fourth is the first clip of the source 5, the second winding 25 of the transducer position, the voltage divider 19, the common bus 10, the second clip channel 5; the fifth is the first clip of the source 5, the second winding 25 of the transducer position, the diode 14, the parallel connected capacitor 11 and resisto is 12, common bus 10, the second clip channel 5; the sixth is the first clip of the source 5, the second winding 25 of the transducer position, the first clamp voltage divider 19, the top of the voltage divider 19, the diode 22, the parallel connected capacitor 20 and resistor 21, the common bus 10, the second clip channel 5. In the negative half-cycle the current flows through the circuit: first - second clip of the source 5, the common bus 10, the voltage divider 15, the first winding 24 of the transducer position, the first clamp source 5, the second - second clip of the source 5, the common bus 10, the voltage divider 19, the second winding 25 of the transducer position, the first clamp source 5. The elements 9, 12, 18, 21 respectively are formed constant voltage V1, V2, V3, V4 relative to a common bus 10. The value of these stresses depends on the position of conductive or amagnitude plot of inductor 23 relative to the transducers position 24 and 25. The voltages V1 and V2 are received at the first inputs, respectively, 7 and 13 of the comparator, and the second input 7 and 13 of the Comparators are given correspondingly constant voltage level V4, V3. In the initial state, as shown in figure 5, the impedance of the transducer 24 position is approximately equal to the complex impedance of the transducer 25 as dumb is nitrovideo (conductive) plot of the inductor 23 is in the area of primary converters 24 and 25. This leads to the fact that V1>V4 and V2>V3 and information on the outputs of the secondary Converter 3 and 4 are formed signals 1 and 1, respectively. When moving inductor 23 figure 5 left to the primary transducer position 24 is supplied conductive (amagnitude) plot of the inductor 23. Therefore, the impedance of the transducer position 24 sharply increases (decreases), whereas the impedance of the transducer position 25 is not changed, which means that the only change is the inequality between V1 and V4 (V2 and V3), i.e., V1<V4 (V2<V3), which leads to the formation of the informational outputs of the secondary Converter 3 and 4 signals 0 and 1 (1 and 0), respectively. When moving coil 23 from the initial condition of figure 5 to the right to the primary transducer position 25 is supplied conductive (amagnitude) plot of the inductor 23. Therefore, the impedance of the transducer position 25 sharply increases (decreases), whereas the impedance of the transducer position 24 is not changed, which means that the only change is the inequality between V2 and V3 (V1 and V4), i.e., V2<V3 (V1<V4), which leads to the formation of the informational outputs of the secondary Converter 3 and 4 signals 1 and 0 (0 and 1), respectively.

Secondary conversion on the tel 1 is a block transducers in figure 2 and the inductor unit transducers figure 6 is as follows.

When submitting from the output of the source 6 harmonic or pulse signal in the first and second half cycles of the current flows along the same circuits described previously. In the initial state, as shown in Fig.6, the impedance of the transducer 24 position is approximately equal to the complex impedance of the transducer 25 as the conductive (amagnitude) plot of the inductor 23 is in the area of primary converters 24 and 25. This leads to the fact that V1>V4 and V2>V3 (V1>V4 and V2>V3) and information on the outputs of the secondary Converter 3 and 4 are formed signals 1 and 1, respectively. When moving the inductor 23 to the left to the primary transducer position 25 is supplied amagnitude (conductive) plot of the inductor 23. Therefore, the impedance of the transducer position 25 sharply decreases (increases), whereas the impedance of the transducer position 24 is not changed, which means that the only change is the inequality between V1 and V4 (V2 and V3), i.e., V1<V4; V2>V3 (V1>V4; V2<V3), which leads to the formation of the informational outputs of the secondary Converter 3 and 4 signals 0 and 1 (1 and 0), respectively. When moving coil 23 from the source state the right to primary transducer position 24 is fed to aminopropoxy (conductive) plot of the inductor 23. Therefore, the impedance of the transducer position 24 sharply decreases (increases), whereas the impedance of the transducer position 25 is not changed, which means that the only change is the inequality between V2 and V3 (V1 and V4), i.e., V1>V4; V2<V3 (V1<V4; V2>V3), which leads to the formation of the informational outputs of the secondary Converter 3 and 4 signals 1 and 0 (0 and 1), respectively.

The secondary Converter in figure 1 with the unit transducers in figure 3 and the inductor unit transducers figure 5 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 windings 26 and 28 of the first 24 and second 25 transducers provisions common bus 10, the second clip channel 5; second, the first terminal of the secondary winding 27 of the first 24 of the transducer position, the diode 6, the parallel connected capacitor 8 and the resistor 9, the common bus 10, the second terminal of the secondary winding 27 of the first 24 of the transducer position; the third, the first terminal of the secondary winding 27 of the first 24 primary Converter position, the first clamp voltage divider 15, the top of the voltage divider 15, a diode 16, parallel the United capacitor 17 and resistor 18, common bus 10, the second terminal of the secondary winding 27 of the first 24 of the transducer position; the fourth - first output of the secondary winding 27 of the first 24 of the transducer position, the voltage divider 15, the common bus 10, the second terminal of the secondary winding 27 of the first 24 of the transducer position; fifth, the first terminal of the secondary winding 29 of the second 25 of the transducer position, the diode 14, the parallel connected capacitor 11 and resistor 12, the common bus 10, the second terminal of the secondary winding 29 of the second 25 of the transducer position; sixth, the first terminal of the secondary winding 29 of the second 25 of the transducer position, the first clamp voltage divider 19, the top of the voltage divider 19, the diode 22, the parallel connected capacitor 20 and resistor 21, the common bus 10, the second terminal of the secondary winding 29 of the second 25 of the transducer position; seventh, the first terminal of the secondary winding 29 of the second 25 of the transducer position, the voltage divider 19, the common bus 10, the second terminal of the secondary winding 29 of the second 25 of the transducer position. In the negative half-cycle the current flows in the three circuits: the first - second clip of the source 5, the common bus 10, the parallel connected primary windings 26 and 28 of the first 24 and second 25 transducers position, the first clamp istochniki; the second terminal of the secondary winding 27 of the first 24 primary Converter provisions common bus 10, the voltage divider 15, the first terminal of the secondary winding 27 of the first 24 of the transducer position; the third, the second terminal of the secondary winding 29 25 second primary Converter provisions common bus 10, the voltage divider 19, the first terminal of the secondary winding 29 of the second 25 of the transducer position. The elements 9, 12, 18 and 21 respectively are formed constant voltage V1, V2, V3 and V4 relative to a common bus 10. The value of these stresses depends on the position of conductive (amagnitude) plot of the inductor 23, on the inner or outer side of the primary converters regulations 24 and 25. In the initial state, as shown in figure 5, there is a weak (strong) mutual inductance transducers regulations 24 and 25, as amagnitude (conductive) plot of the inductor 23 is in the area of primary converters 24 and 25. This leads to the fact that V1>V4 and V2>V3 and information on the outputs of the secondary Converter 3 and 4 are formed signals 1 and 1, respectively. When moving inductor 23 figure 5 left in the area of the primary Converter 24 is supplied conductive (amagnitude) plot of the inductor 23. Therefore, mutual's range of complete Yunosti primary Converter 24 increases (decreases), while the state of the primary Converter 25 is not changed, this means that you change the values of V1 and V3 (V2 and V4). This leads to the fact that V1>V4; V2<V3 (V1<V4; V2>V3) and information on the outputs of the secondary Converter 3 and 4 will provide the state corresponding to 1 and 0 (0 and 1). When moving the inductor 23 to the right in figure 5 the area of the primary Converter 25 is supplied conductive (amagnitude) plot of the inductor 23. Therefore, the mutual inductance of the primary Converter 25 increases (decreases), while the state of the primary Converter 24 does not change, this means that you change the values of V2 and V4 (V1 and V3). This leads to the fact that V1<V4; V2>V3 (V1>V4; V2<V3) and information on the outputs of the secondary Converter 3 and 4 are formed signals 0 and 1 (1 and 0), respectively.

The secondary Converter in figure 1 with the unit transducers in figure 3 and the inductor unit transducers figure 6 is as follows.

When submitting from the output of the source 6 harmonic or pulse signal in the first and second half cycles of the current flows along the same circuits described previously. In the initial state, as shown Fig.6, there is a weak (strong) mutual inductance transducers regulations 24 and 25, as amagnitude (conductive) the area in which octora 23 is in the area of primary converters 24 and 25. This leads to the fact that V1>V4 and V2>V3 and information on the outputs of the secondary Converter 3 and 4 are formed signals 1 and 1, respectively. When moving the inductor 23 to the left in the area of the primary Converter 25 is supplied amagnitude (conductive) plot of the inductor 23. Therefore, the mutual inductance of the primary Converter 25 decreases (increases), whereas the status of the primary Converter 24 does not change, this means that you change the values of V2 and V4 (V1 and V3). This leads to the fact that V1>V4; V2<V3 (V1<V4; V2>V3) and information on the outputs of the secondary Converter 3 and 4 will provide the state corresponding to 1 and 0 (0 and 1). When moving the inductor 23 to the right in the zone of the primary Converter 24 is supplied amagnitude (conductive) plot of the inductor 23. Therefore, the mutual inductance of the primary Converter 24 decreases (increases), whereas the status of the primary Converter 25 is not changed, this means that you change the values of V1 and V3 (V2 and V4). This leads to the fact that V1<V4; V2>V3 (V1>V4; V2<V3) and information on the outputs of the secondary Converter 3 and 4 are formed signals 0 and 1 (1 and 0), respectively.

The secondary Converter in figure 1 with the unit transducers figure 4 works the same as with block transducers figure 3. The difference C is enabled only in this case, the voltage source 5 is not on each primary winding of the transducers position, the chain consisting of these windings connected in series with each other.
