EPRO PR6423000‑000 Eddy Current Displacement Sensor

The EPRO PR6423000‑000 is an eddy‑current displacement transducer designed for non‑contact shaft vibration and position measurement. It detects tiny clearance changes of rotating shafts and converts physical displacement into continuous analog signals for online machine condition monitoring systems.

This high‑precision probe works together with the matching signal converter and features stable temperature drift performance and anti‑interference capability. Original production has been discontinued. It serves as aftermarket spare parts for turbine, compressor and large rotating machinery monitoring cabinet maintenance and retrofitting.

FAQ

1. Q:Does PR6423000‑000 work independently?
   A:No, it must cooperate with a matched signal converter to output available measurement signals.
2. Q:What physical quantities can this probe monitor?
   A:It is mainly used for shaft vibration, axial displacement and rotor clearance monitoring of rotating machines.

3. Q:Is this eddy current displacement sensor still in original production?
   A:EPRO has stopped manufacturing this model, only tested surplus and refurbished spare units are available.
