ABSTRACT:
Disclosed is an externally loaded pressure sensor using a pair of SAW devices formed on the wall of an interior cavity. The difference frequency of these devices is used as a temperature-compensated measure of hydrostatic pressure on the sensor exterior. The termal response time of the sensor is shortened by matching to each other the sensor wall thicknesses adjacent the two SAW devices, e.g., by making these wall thicknesses approximately the same by means of forming an external flat on the sensor body.
