The principle of Reciprocal Pendulum type Pickup is to induce voltage by reciprocal motion of the seismic mass with a coil in the magnetic field being suspended by a diaphragm or coil spring..
Because of its High Sensitivity and Advanced Linearity, it is suitable for detection of malfunction or deterioration of rotational machineries.
Due to its structure, mounting should be done carefully for its direction or angle.
