ABSTRACT:
An inductive displacement transducer is proposed which serves to convert a mechanical movement into an electrical signal and in particular, in order to measure the fuel consumption of an internal combustion engine, the transducer ascertains the movement of an air flow rate meter disposed in the intake tube of the engine. The displacement transducer includes a core comprising two E-shaped sets of arms disposed symmetrically relative to one another, of which one set of arms serves as the measuring arm set, the middle arm of which is surrounded on one end by a measuring magnetic coil and on the other end by a measuring short-circuit ring connected with the air flow rate meter, and the other set of arms acts as a reference arm set, the middle arm of which is surrounded on one end by a reference magnetic coil and on the other end by a fixed reference short-circuit ring. The measuring short-circuit ring is connected with a leaf spring, which is secured on the air flow rate meter.
