Abstract

See full text

A sensor device for high speed rotating machine includes a rotating body and a sensor assembly. The rotating body includes a magnetic permeable ring and at least one positioning structure. The magnetic permeable ring includes a radial displacement sensing area and a rotational speed sensing area, and the positioning feature is arranged in the rotational speed sensing area. The sensor assembly includes four radial displacement sensors and two rotational speed sensors. The radial displacement sensor is a double-probe type sensor, and the speed sensor is a double-probe or four-probe type sensor. Through different types of the rotational speed sensors and the radial displacement sensors, the rotation speed and turning direction of the rotating body can be calculated.
