Abstract

A piezoelectric pressure sensor includes a generally elongate housing, a pressure receiving plate at a first end of the housing with first surface arranged to receive a pressure applied from outside the housing, a pressure transmission member in the housing with a first end in contact with a second surface of the pressure receiving plate, and a tubular piezoelectric element in the housing with a first end in contact with a second end of the pressure transmission member.
A pair of electrodes are formed on the external and internal surfaces of the piezoelectric element. An external member is in contact with the external electrode for collecting a charge on the external electrode and is encircled by a heat-shrinkable tube, while an internal member is in contact with the internal electrode for extracting a charge therefrom. A
screw is threaded into the housing for holding the piezo-electric element and the pressure transmission member against the pressure receiving plate. During assembly of the sensor, the heat-shrinkable tube undergoes thermal shrinkage upon application of heat thereto, thereby compressing the external member radially inwardly against the external electrode.
