Product Overview
The Epro PR6423/003-130 8mm Eddy Current Sensor is a non-contact displacement probe used for measuring shaft position, vibration, and relative movement in rotating machinery. It belongs to the Epro PR6423 series of eddy current sensors and is commonly applied in industrial machinery condition monitoring systems.
The sensor detects the distance variation between the probe tip and the conductive target surface by using electromagnetic eddy current technology. This measurement method allows continuous monitoring of rotating components without physical contact, making it suitable for equipment operating at high speed.
The PR6423/003-130 is typically used together with a compatible signal converter and monitoring module to build a complete machinery protection solution. It is widely installed on turbines, compressors, generators, pumps, and other critical rotating equipment where early detection of abnormal shaft movement is required.

Working Principle
The PR6423/003-130 operates using eddy current displacement measurement technology.
Measurement process:
Rotating Shaft → PR6423/003-130 Eddy Current Sensor → Signal Converter → Monitoring System → Protection Logic
Operating process:
- The sensor generates a high-frequency electromagnetic field around the probe tip.
- The conductive shaft surface influences the electromagnetic field according to the distance between the sensor and target.
- The sensor detects changes in the eddy current response caused by shaft movement.
- The displacement variation is converted into an electrical signal.
- The monitoring system processes the signal to evaluate vibration and shaft position conditions.
The non-contact design enables continuous measurement without introducing mechanical friction or affecting rotating equipment operation.
