Product Introduction

The Epro PR6480/081-000 Eddy Current Sensor is a high-precision, non-contact vibration and displacement sensor specifically developed for industrial machine condition monitoring and protection. As a member of the PR6480 series, it employs eddy current technology to measure the distance between the sensor probe and a conductive target, making it suitable for detecting shaft displacement, vibration amplitude, and dynamic movements in rotating machinery.

This model is designed for demanding industrial environments such as power plants, oil and gas facilities, and large rotating machinery installations. Its rugged stainless steel construction ensures long-term stability, resistance to oil and dust, and immunity to harsh electromagnetic conditions. The PR6480/081-000 provides linear, repeatable, and accurate measurements even under continuous vibration or thermal stress.

The sensor operates in conjunction with Epro CON011, CON021, or CON031 converters, forming a complete eddy current measurement system compliant with API 670 machine protection standards. Its high temperature capability and robust design make it an ideal choice for critical asset protection and predictive maintenance systems.
