摘要： 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.
