Abstract : The patent describes a magnetic field transducer of the variable reluctance type provided with permanent magnetic biasing having a high degree of electromechanical coupling. The arrangement of the mechanical system is such as to isolate the dynamic changes of the air gap from hydrostatic pressures to thereby avoid deterioration of transducer calibration which would result from changes in the air gap length.
