Product Introduction
The Epro PR9670/110-100 Eddy Current Sensor is a high-performance, non-contact sensor specifically designed for displacement and vibration monitoring of rotating and reciprocating machinery. Part of Epro’s PR9670 series, this model is engineered to provide precise, stable, and reliable measurements in challenging industrial environments.
Using the eddy current principle, the sensor generates an electromagnetic field at its probe tip. When a conductive target moves within this field, eddy currents are induced, which produce a voltage signal proportional to the displacement of the target. This allows the PR9670/110-100 to measure shaft vibration, axial movement, and dynamic position changes in real time, making it a critical component in machinery protection systems.
The sensor integrates seamlessly with Epro CON021 proximitor modules and MMS6000 monitoring systems, enabling full monitoring and control of industrial machinery. It is designed to operate accurately under high vibration, wide temperature ranges, and oil-laden or harsh environments.
