Product Introduction

The Epro PR9670/003-000 Eddy Current Sensor is a high-precision, non-contact displacement and vibration measurement device designed for continuous monitoring and protection of rotating and reciprocating machinery. This model belongs to Epro’s advanced PR9670 series, well known for its robust construction, stable performance, and high measurement accuracy even under extreme industrial environments.

The PR9670/003-000 sensor operates on the eddy current principle, generating an electromagnetic field that interacts with a conductive target. Changes in this interaction produce a measurable voltage proportional to the distance between the sensor and the target surface. This allows the sensor to detect shaft displacement, vibration, and position variations in real time.

The sensor is fully compatible with Epro CON021 proximitor modules and MMS6000 monitoring systems, forming a complete condition monitoring solution for turbines, compressors, pumps, and motors. With exceptional linearity, low thermal drift, and high signal stability, it is ideal for use in environments where long-term reliability and precise measurement are critical.
