Présentation du produit
The Epro PR9376/20 is an industrial-grade, non-contact eddy current sensor specifically designed for monitoring the rotational speed and position sur metallic targets in critical rotating equipment. Manufactured by EPRO, a trusted name in condition monitoring and part sur Emerson’s product portfolio, this sensor stands out for its robust performance in aggressive industrial environments such as turbine housings, gearboxes, and centrifugal compressors.
The PR9376/20 sensor is capable sur detecting both speed and proximity by identifying the movement sur ferromagnetic materials (e.g., gear teeth or shaft notches). It is widely used in conjunction with EPRO CON-series signal converters to provide real-time monitoring data for predictive maintenance and protection systems.
Engineered for durability, precision, and stability, the PR9376/20 is suitable for applications requiring reliable operation under high temperature, vibration, and electromagnetic interference.
