製品紹介
The Epro PR9376/20 is an industrial-grade, non-contact eddy current sensor specifically designed for monitoring the rotational speed and position / metallic targets in critical rotating equipment. Manufactured by EPRO, a trusted name in condition monitoring and part / 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 / detecting both speed and proximity by identifying the movement / 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.
