VIBRATING BEAM FORCE-FREQUENCY TRANSDUCER AND PENDULOUS ACCELERATOR COMPRISING APPLICATION THEREOF

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.
