ABSTRACT:
A pressure/force transducer having a sensor body with a load-receiving member at one end, a load button positioned within the sensor body and having a curved surface in surface-to-surface continuous contact with the load-receiving member, a piezoelectric plate positioned within the sensor body and in contact with the load button, and a signal processor for converting the electrical charge produced by the piezoelectric plate into a humanly perceivable signal. A preloading member is connected to the sensor body so as to adjustably force the load button into surface-to-surface contact with the load-receiving member. The load-receiving member is integrally formed with the sensor body. This load-receiving member has a radiused corner connecting the member to the sensor body. The load button is a generally cylindrical member with a generally curved surface in contact with the load-receiving member.
