Product Introduction
The Epro PR9670/010-100 Eddy Current Sensor is a high-precision, non-contact sensor designed for displacement and vibration monitoring of rotating machinery. It is part of Epro’s PR9670 series, which is widely recognized for its reliability, linear response, and durability under extreme industrial environments.
This sensor operates based on the eddy current principle, producing an electromagnetic field at the probe tip. When a conductive target moves within this field, it induces changes in eddy currents, which are then converted into a voltage signal proportional to the target’s displacement. The PR9670/010-100 provides accurate, real-time measurements for machinery monitoring, ensuring the detection of shaft vibration, misalignment, and axial movement.
It is fully compatible with Epro CON021 proximitor modules and MMS6000 monitoring systems, enabling seamless integration into industrial condition monitoring networks. The PR9670/010-100 is engineered to maintain stable performance under vibration, temperature variations, and challenging environmental conditions, making it ideal for turbines, compressors, pumps, motors, and other critical machinery.
