Product Introduction
The Epro PR6480/071-100 Eddy Current Sensor is a precision, non-contact displacement and vibration sensor designed for industrial machine monitoring and protection applications. As part of the PR6480 series, this sensor provides highly accurate measurement of shaft displacement, vibration, and rotational dynamics in critical equipment.
Using eddy current technology, the sensor generates a high-frequency electromagnetic field that induces currents in nearby conductive surfaces. Variations in these currents are detected and analyzed to produce precise measurements of displacement and vibration. This non-contact operation reduces mechanical wear and ensures long-term reliability, even in harsh industrial environments.
The PR6480/071-100 is compatible with Epro CON011, CON021, and CON031 signal converters, making it ideal for integration into complete machine protection and condition monitoring systems. The sensor’s stainless steel housing provides robust protection against oil, dust, vibration, and temperature extremes.
Being API 670 compliant, the sensor is suitable for high-reliability machinery protection systems in power generation, petrochemical, and heavy industry applications, supporting predictive maintenance and early fault detection strategies.
