Abstract: A vibrating force transducer suitable for use in a pendular accelerometer mprises a flat elongated strip of piezo-electric material having end portions arranged for being securely connected to elements which apply a force to be measured along the direction of elongation when the transducer is in service. The strip is fractionated by slits parallel along the direction of elongation and orthogonal to major faces of the strips into a central beam and lateral beams which are in a common plane, the lateral beams carrying electrode means for flexural vibration in the common plane at a resonance frequency indicative of the value of the force applied to the end portions and the central beam carrying a resistive temperature sensor.

Abstract: A pendulous accelerometer comprises a stator defining a cavity having two nfronting surfaces which constitute two electrodes.It also comprises a pendulum consisting of a disc connected to the stator by a hinge. A servo-circuit applies DC forces to the capacitors, each comprising a surface of the cavity and the confronting electrically conductor surface of the pendulum for creating an electrostatic torque which balances the acceleration torque.
