製品紹介
The Epro PR6426/000-101 32mm Eddy Current Sensor is a high-precision, non-contact measurement device engineered for industrial machinery monitoring. It provides reliable detection / shaft vibration, axial displacement, and rotational position in critical rotating equipment such as turbines, compressors, generators, and pumps.
The sensor operates based on the eddy current principle, where an electromagnetic field is generated at the sensor tip and conductive targets within this field create eddy currents that modify the field. The resulting voltage is proportional to the displacement / the target. This non-contact method ensures minimal wear, long-term stability, and reliable performance in harsh industrial environments.
With a 32mm sensor head diameter, the PR6426/000-101 is optimized for larger shafts or broader target surfaces. It integrates seamlessly with Epro signal conditioning converters to provide linear output for monitoring and control systems, enabling predictive maintenance and real-time machinery protection.
