Product Introduction
The Epro PR6480/051-000 Eddy Current Sensor is a precision, non-contact displacement and vibration measurement device designed for industrial condition monitoring and machine protection applications. As a member of the PR6480 series, this sensor offers highly accurate measurement of shaft displacement, vibration, and rotational dynamics in critical machinery.
Using eddy current technology, the sensor generates a high-frequency magnetic field that induces currents in nearby conductive surfaces. Variations in these currents are analyzed to determine precise displacement and vibration, enabling real-time monitoring of machinery without any mechanical contact. This non-contact approach significantly reduces wear and ensures long-term reliability.
The PR6480/051-000 is compatible with Epro CON011, CON021, and CON031 signal converters, forming a complete condition monitoring system for turbines, compressors, pumps, motors, and heavy industrial machinery. Its robust stainless steel housing ensures reliable performance in extreme industrial conditions, including high temperatures, vibrations, and exposure to oil or dust.
This sensor is fully compliant with API 670 standards, making it suitable for integration into high-reliability machinery protection systems used in power generation, process industries, and heavy equipment monitoring.
