Abstract

1,207,562. Piezo-electric transducers. H. LIST. Feb.21, 1968 [June 14, 1967], No.8340/68. Heading G1N. To compensate for errors in measurement due to acceleration forces, a water cooled Piezoelectric transducer e.g. for measuring pressure, comprises a stack or set 12 Fig. 1 of quartz crystal wafers 11 responsive to a force to be measured applied to end portion 10 of a thin walled tubular spring member 7, and a compensating crystal or set of crystals 14 which under acceleration is acted upon by a mass 13 to produce an output of opposite polarity to that of the measuring crystals 12. The upper end of the tube member 7 is welded to an insert 2 and the member 7 holds the crystals and mass 13 under axial compressive pre-stress. Under acceleration conditions the crystals 12 produce an output dependent upon the combined masses of the end portion 10, a ring member 18 of a sealing membrane and a shim member 9 sandwiched between the crystals and portion 10. During calibration tests on a vibrating table, material is removed from the ring 18 and end portion 10 to reduce their mass until the voltage output of crystals 12 exactly balances that of crystal 14 due to acceleration of mass 13. Alternatively, the spring may be in the form of a membrane Fig. 2 (not shown), closing the end of the housing.
