ABSTRACT:
A bridge-type capacitance transducer comprising four active components is disclosed. The symmetry of this transducer is maintained in the presence of capacitance change induced by motion. Consequently, there is greater immunity to extraneous stray capacitances, thus greater sensitivity and range of linearity. Sensitivity is further increased by means of synchronous detection at the output.
