Emerson 8mm Eddy Current Sensor Eddy-current contactless sensor PR6423 003-0D1

Emerson 8mm Eddy Current Sensor Eddy-current contactless sensor PR6423 003-0D1

Non-contact sensor designed for critical turbomachinery applications such as steam, gas and hydro turbines, compressors, gearboxes, pumps and fans to measure radial and axial shaft dynamic displacement; position, eccentricity and speed.

The PR6423 003-0D1 is a radioactive radiation resistant non-contact eddy current transducer. The construction and design allows this sensor to be used in nuclear radiation zone 1 applications on turbomachinery, reactor coolant pumps and other motors, pumps, fans or blowers.

The purpose of a displacement probe is to measure position or shaft movement without contacting the measured surface – the rotor.
