Abstract
A capacitive sensor for use in the measurement of pressure or pressure changes of a fluid medium which sensor maintains the capacitor electrodes in a substantially parallel relationship. Maintenance of this parallel relationship provides a substantially linear capacitive output over a given range without further electronic buffering or calibration. The capacitive signal may be enhanced or amplified by use of multiple parallel plates which are movable simultaneously with deflection of the flexible diaphragm.
