Product Introduction

The Epro PR6453/361-000 12.5mm Eddy Current Sensor is a precision-engineered, non-contact displacement and vibration probe developed for continuous monitoring of rotating and reciprocating machinery. Designed to deliver high accuracy, excellent temperature stability, and long-term reliability, this sensor is a vital component for predictive maintenance and machine protection systems.

Based on the eddy current principle, the PR6453/361-000 generates an electromagnetic field that induces eddy currents in a conductive target surface. The resulting change in impedance is linearly proportional to the target’s displacement or vibration amplitude. This data is then processed by compatible Epro converter modules—typically CON021 or CON041—to produce precise and stable output signals used by machine monitoring and control systems.

With a 12.5 mm sensor head, this model provides excellent balance between measurement range and physical compactness. It is particularly suited for applications where both shaft vibration and relative displacement need to be measured with high precision. The sensor’s rugged stainless-steel body and hermetically sealed design ensure reliable operation in harsh industrial environments, including high temperatures, oil exposure, and areas subject to strong mechanical vibration.

The PR6453/361-000 is widely used in turbines, compressors, pumps, and generators. It forms part of Epro’s PR6453 series of sensors—renowned for their stability, linearity, and compatibility with Epro’s advanced MMS monitoring systems.
