Product Introduction

The Epro PR6480/391-000 Eddy Current Sensor is a high-precision, non-contact vibration and displacement probe engineered for demanding industrial environments. It belongs to the Epro PR6480 series, which is renowned for its robust construction, precise linearity, and long-term operational stability. This model is optimized for accurate measurement of shaft vibration, axial displacement, and relative motion in rotating machinery such as turbines, compressors, pumps, and generators.

The PR6480/391-000 operates based on the eddy current measurement principle, using electromagnetic induction to detect the proximity of a conductive surface. When installed near a rotating shaft or metallic target, the sensor produces a voltage signal proportional to the distance or vibration amplitude. When paired with compatible Epro converter units like CON011, CON021, or CON031, it provides a calibrated linear output that can be directly used for machinery protection or condition monitoring systems.

This sensor is designed to meet the stringent requirements of API 670 and ISO 10817 standards. Built with a stainless-steel body and rated IP67 for environmental protection, it is capable of withstanding exposure to oil, dust, and moisture. It is widely used in heavy industries including power generation, petrochemical processing, and mechanical manufacturing, where reliability and accuracy are essential.
