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.
This series of sensors is basically the same as the 7200 series products of Bentley Corporation and SD-081.082 of Germany, and can be used interchangeably.
