Product Introduction

The Epro PR6453/240-101 12.5mm Eddy Current Sensor is a precision-engineered, non-contact displacement and vibration sensor designed for high-reliability condition monitoring and machinery protection applications. As part of Epro’s PR6453 series, this model delivers exceptional accuracy and long-term stability in demanding industrial environments such as power plants, refineries, and manufacturing facilities.

Operating on the eddy current principle, the PR6453/240-101 detects the distance between the probe tip and a conductive target surface, converting this information into an analog signal. This allows it to precisely measure shaft displacement, vibration, and position without physical contact, eliminating mechanical wear and reducing maintenance needs.

The sensor features a 12.5 mm sensing head, optimized for compact installation spaces where smaller shafts or confined machinery housings are present. When combined with Epro’s CON021 or CON041 converter, the system provides a linearized, temperature-compensated output that integrates easily into Epro’s MMS monitoring systems or other industrial control platforms.

With high electromagnetic resistance, excellent linearity, and robust construction, the PR6453/240-101 represents an ideal solution for continuous monitoring of rotating machinery such as turbines, compressors, and motors in critical operational environments.
