The value and polarity of these voltages depend on the position of the conductive (amagnitude) plot of the inductor 21 relative to the transducers position 22, 23 and 24. In the initial state, as shown in figure 5, the impedance of the transducer 22 is approximately equal to the complex impedance of the transducer 24 and the impedance of the third primary Converter 23 is much more (or less) complex resistance of the first and second transducers as conductive (amagnitude) plot of the inductor 21 is in the area of the third primary Converter 23. This leads to the fact that VI<0 VIII<0; VII<0 (VI<0 VIII>0; VII<0).

When moving inductor 21 figure 5 to the left position in the area of the primary Converter 22 is fed to the conductive (amagnitude) customeruser 21. Therefore, the impedance of the transducer 22 is sharply increases (decreases), whereas the impedance transducers 23 and 24 is not changed, which means that changes the polarity of the VII(VI), i.e. VI<0; VIII<0; VII<0 (VI>0; VIII>0; VII<0). Upon further movement of the inductor 21 figure 5 in the leftmost position of the zone of the transducer 23 is displayed conductive (amagnitude) plot of the inductor 21. Therefore, the impedance of the transducer 23 sharply decreases (increases), whereas the impedance transducers 22 and 24 is not changed, which means that changes the polarity of the VIII(VIII), i.e. VI<0; VIII>0; VII>0 (VI>0; VIII<0; VII<0).

When moving inductor 21 figure 5 from the Central position in the right position in the area of the primary Converter 24 is supplied conductive (amagnitude) plot of the inductor 21. Therefore, the impedance of the transducer 24 is sharply increases (decreases), whereas the impedance transducers 22 and 23 is not changed, which means that changes the polarity of the VI(VII), i.e. VI>0; VIII<0; VII <0 (VI<0; VIII>0; VII>0).

This leads to the fact that VI<0; VIII>0; VII<0 (VI<0; VIII>0; VII<0).

When moving inductor 21 figure 6 to the left position in the area PE the primary of the Converter 24 is supplied amagnitude (conductive) plot of the inductor 21. Therefore, the impedance of the transducer 24 is sharply decreases (increases), whereas the impedance transducers 22 and 23 is not changed. This leads to the formation of the following information signals: VI<0; VIII<0; VII>0 (VI>0; VIII>0; VII<0). Upon further movement of the inductor 21 figure 6 to the left of the zone of the transducer 23 is displayed conductive (amagnitude) plot of the inductor 21. Therefore, the impedance of the transducer 23 sharply decreases (increases), whereas the impedance transducers 22 and 24 is not changed, which means that changes the polarity of the VIII(VIII), i.e. VI<0; VIII>0; VII>0 (VI<0; VIII<0; VII<0). When moving inductor 21 figure 6 from the Central position in the right position in the area of the primary Converter 22 is supplied amagnitude (conductive) plot of the inductor 21. Therefore, the impedance of the transducer 22 sharply decreases (increases), whereas the impedance transducers 23 and 24 is not changed. This leads to the formation of the following information signals: VI>0; VIII<0; VII <0 (VI<0; VIII>0; VII>0). Upon further movement of the inductor 21 at 6 in the extreme right position of the zone of the transducer 23 is displayed conductive (amagnitude) plot of the inductor 21. Therefore, the impedance of the transducer 23 sharply decreases (increases), whereas the impedance transducers 22 and 24 is not changed, which means that changes the polarity of the VIII(VIII), i.e. VI>0; VIII>0; VII<0 (VI<0; VIII<0; VII>0).

The first (“I”), second (II) and third (III) information outputs, respectively, are generated voltage VIVIIand VIIIregarding the shared bus. The value and polarity of these voltages depend on the position of the conductive (amagnitude) plot of the inductor 21 relative to the transducers position 22, 23 and 24. In the initial state, ka is shown in figure 5, mutual inductance of the first 22 and second 24 transducers position approximately the same, and the mutual inductance of the third 24 primary transducer position much more (less) mutual inductances of the first and second transducers as conductive (amagnitude) plot of the inductor 21 is in the area of the transducer 24. This leads to the fact that VI>0; VIII>0; VII>0 (VI<0; VIII<0; VII<0). When moving inductor 21 figure 5 to the left position in the area of the primary Converter 22 is fed to the conductive (amagnitude) plot of the inductor 21. Therefore, the mutual inductance of the primary Converter 22 sharply increases (decreases), while the mutual inductance transducers 23 and 24 is not changed, which means that changes the polarity of the VII(VI), i.e. VI>0; VIII>0; VII<0 (VI<0; VIII<0; VII>0). Upon further movement of the inductor 21 figure 5 to the left, when from the zone of the transducer 23 is displayed conductive (amagnitude) plot of the inductor 21, the mutual inductance of the primary Converter 23 sharply decreases (increases), while the mutual inductance of the primary change is atobatele 22 and 24 is not changed, this means that changes the polarity of the VIII(VIII), i.e. VI>0; VIII<0; VII<0 (VI<0; VIII>0; VII>0). When moving inductor 21 figure 5 from the Central position in the right position, when in the zone of the primary Converter 24 is supplied conductive (amagnitude) plot of the inductor 21, the mutual inductance of the primary Converter 24 sharply increases (decreases), while the mutual inductance transducers 22 and 23 is not changed, which means that changes the polarity of the VI(VI), i.e. VI<0; VIII>0; VII>0 (VI>0; VIII<0; VII<0). Upon further movement of the inductor 21 figure 5 in the extreme right position, when from the zone of the transducer 23 is displayed conductive (amagnitude) plot of the inductor 21, the mutual inductance of the primary Converter 23 sharply decreases (increases), while the mutual inductance transducers 22 and 24 is not changed, which means that changes the polarity of the VIII(VIII), i.e. VI<0; VIII<0; VII>0 (VI>0; VIII>0; VII<0).

The secondary Converter in figure 1 with parallel and according to the included primary and according enabled secondary windings of the primary unit conversions the users 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 in Fig.6, the mutual inductance of all three transducers position approximately the same as conductive (amagnitude) plot of the inductor 21 is in the areas of these transducers. This leads to the fact that VI<0; VIII>0; VII<0 (VI<0; VIII>0; VII<0). When moving inductor 21 figure 6 to the left position in the area of the primary Converter 24 is supplied amagnitude (conductive) plot of the inductor 21. Therefore, the mutual inductance of the primary Converter 24 sharply decreases (increases), while the mutual inductance transducers 22 and 23 is not changed. This leads to the fact that VI>0; VIII>0; VII<0 (VI<0; VIII<0; VII>0). Upon further movement of the inductor 21 figure 6 to the left of the zone of the transducer 23 is displayed conductive (amagnitude) plot of the inductor 21. Therefore, the mutual inductance of the primary Converter 23 sharply decreases (increases), while the mutual inductance of the primary of the Converter is ately 22 and 24 is not changed. This leads to the fact that VI>0; VIII<0; VII<0 (VI<0; VIII>0; VII>0). When moving inductor 21 figure 6 from the Central position in the right position in the area of the primary Converter 22 is supplied amagnitude (conductive) plot of the inductor 21. Therefore, the mutual inductance of the primary Converter 22 sharply decreases (increases), while the mutual inductance transducers 23 and 24 is not changed. This leads to the fact that VI<0; VIII>0; VII>0 (VI>0; VIII<0; VII<0). Upon further movement of the inductor 21 at 6 in the extreme right position of the zone of the transducer 23 is displayed conductive (amagnitude) plot of the inductor 21, the mutual inductance of the primary Converter 23 sharply decreases (increases), while the mutual inductance transducers 22 and 24 is not changed, which means that changes the polarity of the VIII(VIII), i.e. VI<0; VIII<0; VII>0 (VI>0; VIII>0; VII<0).

The secondary Converter in figure 1 with the unit transducers figure 4 works the same as with block transducers figure 3. The only difference lies in the fact that in this case the voltage from source 6 supplies the I'm not on each primary winding of the primary converters provisions and on a chain consisting of these windings connected in series with each other.

In all versions of unit transducers provisions in this sensor there is a correlation channels, when the change of the impedance (mutual inductance) one of the primary converters affect the values of the voltages from the information outputs of the secondary Converter. This effect is enhanced if the source is time-varying signal to use a current source. In this Converter the signs of the output voltage, which is informative parameters are not changed.
