ABSTRACT:
A variable reluctance transducer includes a C-shaped assembly defining a magnetic circuit, one limb of the C being longer than the other. The assembly is arranged with its limbs on opposite sides of a movable member. A winding linked to the magnetic circuit is connected to a discriminating circuit including an integrator having a variable bias circuit which ensures that the peaks of the integrator output are in a predetermined relationship to a reference voltage. A comparator compares the integrator output with the reference voltage.
