Product Introduction
The Epro PR6480/071-000 Eddy Current Sensor is a high-precision, non-contact displacement and vibration sensor designed for industrial condition monitoring and machine protection. It is part of the PR6480 series and provides accurate measurement of shaft displacement, vibration, and rotational dynamics in critical machinery.
The sensor operates using eddy current technology, producing a high-frequency electromagnetic field that induces currents in nearby conductive surfaces. Changes in these currents are monitored to provide precise measurements of displacement and vibration, allowing real-time, non-contact monitoring. This non-contact design minimizes mechanical wear and increases long-term reliability even in harsh industrial environments.
The PR6480/071-000 integrates seamlessly with Epro CON011, CON021, and CON031 signal converters, enabling complete machine protection and condition monitoring systems. The sensor’s stainless steel housing ensures durability in environments exposed to oil, dust, vibration, and high temperatures.
This sensor is API 670 compliant, making it suitable for high-reliability machinery protection systems in power generation, petrochemical, and heavy industrial applications.
