摘要
The transducer comprises an elongate plate of piezoelectric material, which plate is intended to be fixed at its two ends on components for the application of a longitudinal force to the plate, divided in its medium portion to constitute two lateral beams (20) carrying electrodes (24-26) to set the beams into vibration in the plane of the major faces of the plate and to measure the frequency of vibration. The plate comprises a central beam (22) carrying a resistive temperature sensor (36), which beam is separated from the lateral beams by longitudinal slits (18) perpendicular to the major surfaces of the plate.
