  • Apparatus subject to random accelerative motion for sensing motion of a magnetically susceptible part
    Patent number: 4684888
    Abstract: A magnetically susceptible part motion sensor where the sensor is subject to random accelerative conditions. The sensor comprises a first accelerometer and magnet combination and a second accelerometer and nonmagnetic body combination. The accelerometers are substantially identical and the nonmagnetic body is substantially identical in weight, size and other characteristics to the magnet. Therefore the signal produced by the accelerometers due to random accelerative motion are identical but the first accelerometer produces a signal component corresponding to the passage of the magnetically susceptible part. A differential amplifier is connected to receive the outputs of the two accelerometers and to produce an output signal corresponding substantially only to the passage of the magnetically susceptible part.
