ABSTRACT:
An inductive transducer intended, according to the invention, for converting the displacement of mechanical objects into an electric signal, comprising primary and secondary coils with cores, connected to one of mutually moving mechanical objects. The coils are arranged one opposite the other with a gap, wherein a main screen connected to the other moving object and at least one auxiliary screen are located. The auxiliary screen is set movably in a plane parallel to the main screen. The inductive transducer of this invention permits obtaining a functional relationship between the output signal and two or more displacements of mechanical objects, and thereby enables the relationship, including the slope thereof, to be controlled by simple means.
