A method of shielding a capacitive pressure transducer by positioning an insulated shield spacer between the capacitor electrodes, covering the two electrodes with an electrically conductive shield box, applying a sensor voltage from a first voltage source across the two electrodes, and applying a shield voltage from a second voltage source to the insulated shield spacer and to the shield box.

Method of shielding capacitive pressure sensor

A capacitive pressure transducer includes a shielded spacer positioned between the capacitor electrodes and driven with a separate voltage source.
