Product Introduction
The Epro PR9670/001-000 Eddy Current Sensor is a high-performance non-contact displacement and vibration measurement device developed for industrial machinery protection and condition monitoring applications. Based on Epro’s advanced eddy current technology, it provides accurate, reliable, and repeatable measurements of shaft vibration, position, and movement in rotating equipment.
Designed for use in critical systems such as turbines, compressors, and pumps, the PR9670/001-000 delivers exceptional signal stability even under severe operating environments involving high temperature, oil mist, and mechanical vibration. The sensor operates by generating an electromagnetic field that induces eddy currents in a metallic target. The amplitude of these currents varies with the target’s proximity, enabling precise detection of displacement and motion changes.
The PR9670/001-000 represents a balance between precision engineering, robust design, and compatibility with Epro’s comprehensive monitoring platforms such as CON021 proximitor modules and MMS6000 condition monitoring systems. It is widely utilized for both static and dynamic machinery monitoring where accuracy and dependability are essential.

FAQ
-
What measurement principle does the PR9670/001-000 use?
It operates on the eddy current principle, where a magnetic field induces eddy currents in a metallic target, and the resulting impedance changes are translated into displacement signals. -
Can the PR9670/001-000 measure both static and dynamic motion?
Yes, the sensor can simultaneously measure static shaft displacement and dynamic vibration, making it suitable for complex monitoring tasks. -
What type of output signal does it provide?
The sensor provides a voltage output proportional to the gap between the probe and the target surface, allowing direct integration into monitoring modules. -
Is the PR9670/001-000 compatible with the CON021 proximitor module?
Yes. It is fully compatible with Epro’s CON021 proximitor, ensuring accurate signal conversion and stable monitoring. -
How does the sensor handle temperature variations?
The sensor’s components are temperature-compensated to minimize drift, maintaining accuracy across temperatures from -35°C to +180°C. -
Can this sensor operate in environments with oil contamination or high humidity?
Yes. The IP67-rated construction provides full protection against oil, dust, and moisture ingress. -
What kind of materials are suitable targets for this sensor?
Conductive metals such as steel, aluminum, and copper provide optimal response to eddy current excitation. -
