Product Introduction

The Epro PR6426/010-020 32mm Eddy Current Sensor is a precision non-contact sensor designed to measure displacement, vibration, and shaft position in rotating and reciprocating machinery. It operates on the eddy current principle, detecting the distance between the probe tip and a conductive target surface, ensuring high accuracy and stability under a wide range of industrial conditions.

Developed as part of the Epro PR6426 series, this model provides outstanding performance for machinery protection and condition monitoring systems. It is typically used in conjunction with Epro’s CON021 converter, which processes and conditions the sensor’s analog signals into standardized outputs for monitoring systems. The PR6426/010-020 features a 32 mm probe head, delivering superior sensitivity, signal linearity, and operational reliability even in harsh environments exposed to heat, vibration, and contamination.

The sensor’s rugged construction and wide frequency response range make it ideal for continuous monitoring of turbines, compressors, pumps, and motors, where early detection of mechanical faults can prevent costly downtime.
