Eddy Current Sensor Model;HAD-85811-00+85745-00 Eddy current sensor is a non-contact displacement sensor based on the principle of eddy current effect. The sensor consists of a probe, a lengthened cable, and a driver. It is used to measure various operating state parameters of the rotating mechanical shaft: radial vibration of the shaft, axial displacement, rotational speed, eccentricity, and differential expansion.
