Présentation du produit
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 sur 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 sur these currents varies with the target’s proximity, enabling precise detection sur 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.
