Date Aug. 5, 1982.A piezoelectric transducer for use in accelerometer or vibration measurements comprises a seismic mass in the form of a casing which receives a pair of piezoelectric rings sandwiching between them a flange of a contact pin which extends axially from one end of the casing and is insulated with respect to this end by an insulating bushing. A threaded member of the casing forms one terminal of the transducer while the contact pin forms the other terminal. The rings are braced against a disk of another pin extending axially in the opposite direction from the casing and a spring is braced against this disk and a gasket threaded into the casing.</p> |
