Figure 1 shows a sensor for three-position control within the scope of independent claim 1. Figure 2, figure 3 and figure 4 disclosed variants of the block of primary position transducers and its connection to the secondary Converter. In Fig.5, Fig.6 schematically shows the location of the Central magnetically conductive (non-magnetic) portion of the inductor having a shorter or longer length "b" compared to the distance "a" between the first and second primary position transducers. In Fig.7 and Fig.8, respectively, three zones of unique position control are shown. Their difference lies in the fact that while maintaining the length of the inner zone equal to "c + d" (see Fig. 5, 6), the length "b" of the side zones in Fig. 8 (which corresponds to Fig. 6) is longer than Fig.7 (which corresponds to Fig.5) by the value of "c + d". Thus, by varying the distance "a" between the primary transducers, the length "b" of the magnetically conductive (or non-magnetically conductive) section, "a-b = c + d" (Fig. 5) or "b-a = c + d" (Fig. 6), you can set the necessary three zones of position control.

The block of primary transducers of position 1 of the sensor in Fig. 4 contains an inductor 19 located inside or outside of two independent transformer primary transducers of position 20 and 21, each of which contains a primary and secondary windings 22, 23 and 24, 25, and the first output of the primary winding 22 the first 20 and second terminal of the primary winding 24 of the second 21 independent transformer primary position transducers are interconnected, the second terminal of the primary winding 22 of the first 20 and the first terminal of the primary winding 24 of the second 21 are independent of the transformer primary position transducers are connected respectively to the first and second inputs of the primary transducer block 1, to the first and second outputs of which are respectively connected the first leads of the secondary windings 23 and 25 of the first 20 and second 21 independent transformer primary position converters, in which the second leads of the secondary windings 23 and 25 are connected to the second input of the block of primary position converters 1.

The secondary Converter in figure 1 with the block of primary converters in figure 2 and the inductor of the block of primary converters in figure 5 works as follows.

When a harmonic or pulse signal is supplied from the output of source 5 to a positive half-cycle, the current flows through the chains: the first - the first terminal of the source 5, the winding 20 of the first primary position transducer, diode 7, capacitor 9, common bus 10, the second terminal of source 5; the second is the first clamp of the source 5, the winding 20 of the first primary position transducer, diode 7, resistor 17, resistor 11, common bus 10, the second clamp of the source 5; the third is the first clamp of the source 5, the winding 21 of the second primary position transmitter, diode 15, the capacitor 12, the common bus 10, the second clamp of the source 5; the fourth is the first terminal of source 5, the winding 21 of the second primary position transmitter, diode 15, resistor 18, resistor 13, common bus 10, the second terminal of source 5. During the negative half-cycle, current flows through the circuits: the first is the second terminal of source 5, common bus 10 , diode 6, winding 20 of the first primary position transducer, first source clip 5; the second is the second terminal of the source 5, the common bus 10, the diode 14, the winding 21 of the second primary position transmitter, the first terminal of the source 5. At the elements 11, 13, 17, 18, respectively, constant voltages VI, V2, V3, V4 are formed relative to the common bus 10 The value of these voltages depends on the position of the magnetically conductive portion of the inductor 19 relative to the primary position converters 20 and 21. The voltages V3 and V4 are supplied to the first inputs of the first 8 and second 16 comparators, and the second inputs of the first 8 and second 16 comparators are fed from tvetstvenno voltage V2 and VI. In the initial state, as shown in FIG. 5, the complex resistance of the primary position transducer 20 is approximately equal to the complex resistance of the primary position transducer 21, since the non-magnetic (magnetic) portion of the inductor 19 is in the area of the primary transducers 20 and 21. This leads to that V1 <V4; V2 <V3 (V1 <V4; V2 <V3) and signals 1 and 1 (1 and 1) are generated at the information outputs of the secondary converter 3 and 4, respectively. When moving the inductor 19 in Fig. 5 to the left, a magnetically conductive (non-magnetic) portion of the inductor 19 is brought to the primary position transmitter 20, the complex resistance of the primary position transmitter 20 sharply increases (decreases), while the complex resistance of the primary position transmitter 21 does not change, which means that only the inequality between V2 and V3 (V1 and V4) changes, i.e. V1 <V4; V2> V3 (V1> V4; V2 <V3), signals 0 and 1 (1 and 0), respectively, are generated at the information outputs 3 and 4 of the secondary converter. When the inductor 19 moves from the initial state in FIG. 5 to the right, the magnetically conducting (non-magnetic) section of the inductor 19 is brought to the primary position transmitter 21, the complex resistance of the primary position transmitter 21 sharply increases (decreases), while the complex resistance of the primary position converter 20 does not change, but this means that only the inequality between V1 and V4 (V2 and V3) changes, i.e. V1> V4; V2 <V3 (V1 <V4; V2> V3), signals 1 and 0 (0 and 1), respectively, are formed at the information outputs 3 and 4 of the secondary converter.

The secondary Converter in figure 1 with the block of primary converters in figure 2 and the inductor of the block of primary converters in Fig.6 works as follows.

When a harmonic or pulse signal is supplied from the output of source 5 to the first and second half-periods, currents flow along the same circuits as previously described. In the initial state, as shown in Fig.6, the complex resistance of the primary position transducer 20 is approximately equal to the complex resistance of the primary position transducer 21, since the magnetically conductive (non-magnetic) portion of the inductor 19 is in the area of the primary transducers 20 and 21. This leads to that V1 <V4; V2 <V3 (V1 <V4; V2 <V3) and signals 1 and 1 (1 and 1) are generated at the information outputs of the secondary converter 3 and 4, respectively. When moving the inductor 19 in Fig. 6 to the right, a non-magnetic (magnetic) section of the inductor 19 is supplied to the primary position transmitter 20, the complex resistance of the primary position transmitter 20 sharply decreases (increases), while the complex resistance of the primary position converter 21 does not change, which means that only the inequality between V2 and V3 (V1 and V4) changes, i.e. V1 <V4; V2> V3 (V1> V4; V2 <V3), signals 0 and 1 (1 and 0), respectively, are generated at the information outputs 3 and 4 of the secondary converter. When the inductor 19 moves from the initial state in FIG. 6 to the left, a non-magnetic (magnetic) section of the inductor 19 is brought to the primary position transmitter 21, the complex resistance of the primary position transmitter 21 sharply decreases (increases), while the complex resistance of the primary position transmitter 20 does not change, but this means that only the inequality between V1 and V4 (V2 and V3) changes, i.e. V1> V4; V2 <V3 (V1 <V4; V2> V3), signals 1 and 0 (0 and 1), respectively, are formed at the information outputs 3 and 4 of the secondary converter.

The secondary Converter in figure 1 with the block of primary sensors in figure 3 and the inductor of the block of primary sensors in figure 5 works as follows.

When a harmonic or pulse signal is supplied from the output of source 5 to a positive half-cycle, the current flows through the chains: the first - the first terminal of the source 5, the primary windings 22 and 24 of the first and second primary position transducers, the common bus 10, the second terminal of the source 5; the second is the first terminal of the secondary winding 23 of the first 20 primary position transducer, diode 7, capacitor 9, a common bus 10, the second terminal of the secondary winding 23 of the first 21 primary position transducer; the third is the first terminal of the secondary winding 23 of the first 20 primary position transducer, diode 7, resistor 17, resistor 11, common bus 10, the second terminal of the secondary winding 23 of the first 20 primary position transducer; the fourth is the first terminal of the secondary winding 25 of the second 21 primary position transmitter, the diode 15, the capacitor 12, a common bus 10, the second terminal of the secondary winding 25 of the second 21 primary position transmitter; fifth - the first terminal of the secondary winding 25 of the second 21 primary position transducer, diode 15, resistor 18, resistor 13, common bus 10, the first terminal of the secondary winding 25 of the second 21 primary position transducer. In the negative half-cycle, the current flows through three parallel circuits: the first is the second terminal of the source 5, the common bus 10, the primary windings 22 and 24 of the first 20 and second 21 primary position transducers, the first terminal of the source 5; the second is the second terminal of the secondary winding 23 of the first 20 primary position transmitter, a common bus 10, diode 6, the first terminal of the secondary winding 23 of the first 20 primary position transmitter; the third is the second terminal of the secondary winding 25 of the second 21 primary position transmitter, diode 14, the first terminal of the secondary winding 25 of the second 21 primary position transmitter. Constant voltages V1, V2, V3, V4 are formed on the elements 11, 13, 17, 18 relative to the common bus 10. The value of these voltages depends on the position of the magnetically conducting section of the inductor 19 relative to the primary position converters 20 and 21. The voltages V3 and V4 are applied to the first the inputs of the first 8 and second 16 comparators, respectively, and the second inputs of the first 8 and second 16 comparators are supplied with voltage V2 and V1, respectively. In the initial state, as shown in figure 5, the minimum (maximum) mutual inductance of the primary position transducers 20 and 21, since the non-magnetic (magnetic) portion of the inductor 19 is in the area of the primary transducers 20 and 21. This leads to the fact that V1 <V4; V2 <V3 (V1 <V4; V2 <V3), signals 1 and 1 (1 and 1), respectively, are generated at the information outputs 3 and 4 of the secondary converter. When moving the inductor 19 in Fig. 5 to the left, the magnetically conductive (non-magnetic) portion of the inductor 19 is supplied to the primary position transmitter 20, the mutual inductance increases (decreases) and the secondary voltage taken from the winding 23 of the primary position converter 20 increases (decreases), whereas the state of the primary position transmitter 21 does not change, which means that only the inequality between V2 and V3 (V1 and V4) changes, i.e. V1> V4; V2 <V3 (V1 <V4; V2> V3), signals 0 and 1 (1 and 0), respectively, are generated at the information outputs 3 and 4 of the secondary converter. When the inductor 19 moves from the initial state in FIG. 5 to the right, the magnetically conducting (non-magnetic) section of the inductor 19 is brought to the primary position transmitter 21, the mutual inductance increases (decreases) and the secondary voltage removed from the winding 25 of the primary position converter 21 increases (decreases) , while the state of the primary position transmitter 20 does not change, which means that only the inequality between V1 and V4 (V2 and V3) changes, i.e. V1> V4; V2 <V3 (V1 <V4; V2> V3), signals 1 and 0 (0 and 1), respectively, are formed at the information outputs 3 and 4 of the secondary converter.

The secondary Converter in figure 1 with the block of primary sensors in figure 3 and the inductor of the block of primary sensors in figure 6 works as follows.

When a harmonic or pulse signal is supplied from the output of source 5 to the first and second half-periods, currents flow along the same circuits as previously described. In the initial state, as shown in Fig.6, the maximum (minimum) mutual inductance of the primary position transducers 20 and 21, since the magnetically conductive (non-magnetic) portion of the inductor 19 is in the area of the primary transducers 20 and 21. This leads to the fact that V1 <V4; V2 <V3 (V1 <V4; V2 <V3), signals 1 and 1 (1 and 1), respectively, are generated at the information outputs 3 and 4 of the secondary converter. When moving the inductor 19 in Fig. 6 to the right, a non-magnetic (magnetic) section of the inductor 19 is supplied to the primary position transmitter 20, the mutual inductance decreases (increases) and the secondary voltage taken from the winding 23 of the primary position converter 20 decreases (increases), whereas the state of the primary position transmitter 21 does not change, which means that only the inequality between V2 and V3 (V1 and V4) changes, i.e. V1> V4; V2 <V3 (V1 <V4; V2> V3), signals 0 and 1 (1 and 0), respectively, are generated at the information outputs 3 and 4 of the secondary converter. When the inductor 19 moves from the initial state in FIG. 6 to the left, the non-magnetic (magnetic) section of the inductor 19 is fed to the primary position transmitter 21, the mutual inductance decreases (increases) and the secondary voltage removed from the winding 25 of the primary position converter 21 decreases (increases) , while the state of the primary position transmitter 20 does not change, which means that only the inequality between V1 and V4 (V2 and V3) changes, i.e. V1> V4; V2 <V3 (V1 <V4; V2> V3), signals 1 and 0 (0 and 1), respectively, are formed at the information outputs 3 and 4 of the secondary converter.

The secondary Converter in figure 1 with the block of primary sensors in figure 4 works the same way as with the block of primary sensors in figure 3. The only difference is that in this case, the voltage from the source 5 is supplied not to each primary winding of the primary position transducers, but to the chain consisting of these windings connected in series with each other.
