Eddy Current Displacement Transducer Specifications

The PR 6423 is a non-contact eddy current transducer with a rugged construction and designed for extremely critical turbomachinery applications such as steam, gas, compressor and hydro turbomachinery, blowers and fans.

In the case of sleeve bearing machines, the shaft is separated from the bearing material by a thin film of oil. The oil acts as a dampener and therefore the vibration and position of the shaft are not transmitted through the bearing to the bearing case.

The ideal method of monitoring shaft position and motion is by mounting a non-contact eddy sensor through the bearing, or inside the bearing, measuring the shaft motion and position directly. The PR 6423 is commonly used to measure vibration of machine shafts, eccentricity, thrust (axial displacement), differential expansion, valve position, and air gaps.
