Abstract

The output of the microcapacitance transducer with a four-phase measuring circuit inevitably presents zero drift

so that the stability of the transducer is effected.Investigation of zero drift phenomena of the microcapacitance transducer circuit is studied.A design of stability of zero-point and circuit is given.The effect of the devices in the circuit on stability of zero-point as well as methods of choosing devices is explained.
