Abstract

1,225,799. Piezo electric transducers. KISTLER INSTRUMENTE A.G. June 19, 1968 [Sept. 5, 1967], No.29172/68. Heading G1N. A force transducer for measuring forces in three mutually perpendicular directions comprises three pairs of piezo-electric discs 21, 22; 23, 24 and 25, 26, each pair being predominantly responsive to forces in a respective direction. The piezo-electric discs are superimposed with interleaved electrodes and mounted within a pre-stressed casing. As shown in Fig. 1, a cylindrical or rectangular casing 1 has end-plates 4, 5 provided with resilient flanges 6 welded to the casing. In an arrangement, Fig. 4 (not shown), for investigating shock wave passages, the piezoelectric discs may be mounted within a resilient tubular member (39) together with an inertia mass (51) and an additional piezo-electric disc (52) for acceleration compensation. In another arrangement, Fig. 5 (not shown), for aerodynamic experiments, the force transducer is combined with a torque transducer comprising two axially spaced shear responsive piezo-electric discs (68, 69). In another arrangement, Fig. 6 (not shown), for measuring acceleration, an inertia mass (90) is disposed within a pre-stressed casing between two sets of piezo-electric discs. In another arrangement for measuring acceleration, Fig. 7 (not shown), an inertia mass (112) is mounted within a pre-stressed resilient tubular member (113), undue lateral movement of the inertia mass being restrained by a diaphragm (118) connected to the centre of the face of the inertia mass remote from the piezo-electric discs.
