ABSTRACT:
An electromechanical transducer employs an Eddy current type displacement sensing device mounted in confronting relation to a seismically supported, nonmagnetic metal beam which is presented within an enclosed chamber. Movement of the nonmagnetic metal beam is damped. Movement of the nonmagnetic metal beam relative to the Eddy current type displacement sensing device occurs when the device is moving cyclically at low frequencies up to about 200 Hertz. Because of the damping of the movement of the metal beam, its instantaneous displacement is proportional to the instantaneous acceleration applied to the transducer. The output electrical signal from the Eddy current displacement sensing device can be integrated to provide an output signal directly proportional to the instantaneous velocity of the transducer. The signal can be twice integrated to provide an output signal corresponding to the instantaneous displacement of the transducer.
