Epro PR9670/000-000 Eddy Current Sensor

Product Introduction

The Epro PR9670/000-000 Eddy Current Sensor is a precision-engineered, non-contact displacement and vibration sensor designed for continuous monitoring of critical rotating machinery. Built on Epro’s advanced eddy current measurement technology, this model delivers highly stable and accurate results for shaft position, vibration, and relative motion detection. The PR9670/000-000 is part of the renowned Epro PR9600 series, which has become a global standard for condition monitoring in industries such as petrochemical, power generation, steel, and heavy machinery.

The sensor operates on the eddy current principle, generating a magnetic field that induces eddy currents on a conductive target. The resulting changes in impedance are converted into a voltage signal proportional to the target’s displacement. With its superior linearity, thermal stability, and robust construction, the PR9670/000-000 ensures reliable operation even under severe temperature fluctuations, oil contamination, and vibration stress. It is the preferred choice for engineers requiring accurate and long-term machinery protection in mission-critical environments.

FAQ

1. What measurement technology does the PR9670/000-000 use?
   The sensor uses the eddy current measurement principle, detecting displacement by monitoring variations in electromagnetic field response to a conductive target.

2. Can this model measure both static and dynamic displacements?
   Yes. It measures both static position changes (DC component) and dynamic vibrations (AC component) with high precision.

3. What type of output does the sensor provide?
   It provides a voltage output proportional to the gap distance between the probe and the target, suitable for direct signal processing by Epro modules.

4. Is the PR9670/000-000 compatible with Epro CON021 modules?
   Yes, it is fully compatible with the Epro CON021 proximitor and MMS monitoring systems for signal amplification and diagnostics.

5. How is temperature stability ensured in this sensor?
   The sensor’s materials and internal compensation design maintain stable operation across temperatures from -35°C to +180°C.

6. Can it operate in oil-contaminated or humid environments?
   Yes. Its IP67-rated housing ensures complete resistance to oil, moisture, and dust intrusion.

7. How is the probe installed and calibrated?
   The probe is threaded into a fixed mount at the appropriate distance from the target surface. Calibration is done using a proximitor to match sensitivity specifications.

8. What materials are suitable as targets for accurate readings?
   Conductive materials such as steel, aluminum, or copper provide optimal eddy current response for accurate displacement measurement.

9. Is shielding required to protect against electrical interference?
