| 摘要 |
The invention relates to a transducer with a differential transformer 1, which is linear or nonlinear, comprising a primary coil P connected by two supply wires 2 and 3 to an external alternating current source G and two secondary coils S1 and S2, magnetically coupled to the primary coil by a magnetic core 4 which can move with respect to the coils, which secondary coils are mounted in parallel between two terminals D and E. According to the invention, the secondary coils are mounted respectively in series with two rectifiers T1 and T2 with polarities which are opposed or not opposed, and these terminals D and E are connected to the primary coil by an adder circuit Rc-C adapted to superimpose onto the supply voltage in the wires 2 and 3 a measurement voltage Vc; an output circuit R-F is provided at a distance in order to separate these voltages so as to deliver a measurement signal. <IMAGE>
