Product Introduction
The Epro PR6480/2K1-000 Eddy Current Sensor is a precision-engineered, non-contact displacement and vibration measurement device designed for high-performance industrial monitoring applications. As a member of the Epro PR6480 series, it represents an advanced generation of eddy current sensors used in rotating machinery condition monitoring and machine protection systems.
This model utilizes the eddy current principle to detect minute variations in the distance between the sensor tip and a conductive target. The sensor generates a stable and linear output proportional to the displacement, allowing accurate measurement of shaft vibration, axial position, and clearance in critical rotating equipment.
The PR6480/2K1-000 is specifically optimized for industrial reliability, featuring rugged stainless-steel construction, excellent resistance to oil, dust, and electromagnetic interference, and wide temperature tolerance. When used together with compatible Epro CON011, CON021, or CON031 converters, the sensor delivers precise, linear, and temperature-compensated output signals that comply with API 670 machine protection standards.
Its compact design, superior repeatability, and durability make it ideal for integration into power generation, petrochemical, and heavy industrial systems, where accurate, real-time measurement of machine vibration is crucial to operational safety and reliability.
