Product Introduction
The Epro PR6480/061-000 Eddy Current Sensor is a precision, non-contact displacement and vibration measurement device designed for industrial condition monitoring and machine protection applications. Part of the PR6480 series, this sensor delivers high-accuracy measurement of shaft displacement, vibration, and rotational movement in critical machinery.
Using eddy current technology, the sensor produces a high-frequency electromagnetic field that induces currents in nearby conductive surfaces. Variations in these currents are analyzed to determine precise displacement and vibration values, allowing real-time, non-contact monitoring. This eliminates mechanical wear and ensures long-term reliability, even in harsh industrial environments.
The PR6480/061-000 integrates with Epro CON011, CON021, and CON031 signal converters, forming a complete condition monitoring system for turbines, compressors, pumps, motors, and heavy machinery. Its stainless steel housing provides robust protection against oil, dust, vibration, and high temperatures, ensuring dependable operation in demanding industrial conditions.
It is API 670 compliant, making it suitable for integration into high-reliability machine protection systems and predictive maintenance programs in power generation, petrochemical, and heavy industry applications.
