Product Introduction
The Epro PR6480/051-100 Eddy Current Sensor is a high-precision, non-contact displacement and vibration measurement device engineered for industrial machinery monitoring and machine protection applications. As part of the PR6480 series, this sensor is designed for accurate measurement of shaft displacement, vibration, and rotational dynamics in critical equipment.
The sensor employs eddy current technology, which generates a high-frequency electromagnetic field that induces eddy currents in conductive surfaces. Variations in these currents are measured to calculate precise displacement and vibration, providing real-time monitoring without mechanical contact. This approach reduces wear, increases reliability, and allows for operation in harsh industrial environments.
The PR6480/051-100 integrates seamlessly with Epro CON011, CON021, and CON031 signal converters, enabling deployment in complete monitoring systems for turbines, compressors, pumps, motors, and heavy industrial machinery. The sensor’s stainless steel housing ensures robust operation under extreme conditions including high temperature, vibration, oil mist, and dust.
It is fully API 670 compliant, making it suitable for use in critical machine protection systems, predictive maintenance programs, and condition-based monitoring in industries such as power generation, petrochemical, and heavy machinery manufacturing.
