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