製品紹介
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 / 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 / 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 台s 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 / API 670 and ISO 10817 standards. Built with a stainless-steel body and rated IP67 for environmental protection, it is capable / 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.
