ABSTRACT:
A torque transducer for measuring the torque in the outgoing crankshaft of automobile engines comprises two two-pole magnetic cores, arranged perpendicular to each other, with coils around the poles. The coils of one core are adapted to be supplied with alternating current for generation of an alternating field in the surface of the shaft. The second core with its coils is adapted to sense the changes in the alternating field which are caused by the torque of the engine. The poles of the primary core are located opposite to diametrically opposed points on the crankshaft.
