The Epro PR6423/003-030+CON021 Eddy Current Sensor System is a non-contact displacement measurement assembly consisting of an 8 mm eddy current probe and a CON021 signal converter. It is mainly used for monitoring shaft displacement, vibration behavior, and mechanical condition of high-speed rotating equipment.
In industrial machinery, the relative position between the rotating shaft and stationary components directly affects equipment operating stability. The PR6423/003-030 probe measures shaft movement by detecting changes in the electromagnetic field, while the CON021 converter processes the probe signal and provides a standardized output for connection to vibration monitoring and protection systems.
This sensor system is commonly applied in turbine, compressor, generator, and pump monitoring applications where continuous and accurate displacement measurement is required.
