Abstract: A method of manufacture and a piezoelectric transducer are provided having a housing whose interior contains a piezoelectric element having radially spaced surfaces which undergo relative shear and produce an electrical signal in response thereto, an outer radial surface of the piezoelectric element being soldered to the interior of the housing, and an inner radial surface of the piezoelectric element is soldered to the outer surface of a stress/strain transmitting element. The solder alloy used shrinks less than →2.5% solidification. The subassembly made up of the piezoelectric element and the stress/strain transmitting element is provided with a passage to permit escape of gas from a chamber above the piezoelectric member which may be present from vapors attendant soldering.
