Capacitive Sensors

Jul 20, 2000 · Direct motion applications are common, with capacitive sensors used for non-contact measure-ment of angle, long-throw linear displacement, and sub-micron plate spacing. Several different arrangements of sensing electrodes are used, depending on the measurement job.

Outputs are stable with capacitive loads of over 500 pF. Supply current is less than 300 μA per amplifier at 5 V. 500 Ω series resis-tors protect the inputs, allow ing input signal levels several volts above the positive supply with out phase reversal. Applications for these amplifiers include both line-powered and
