Overview

The Bently Nevada 18745-04 Proximitor Sensor from the 7200 Series is engineered for high-precision vibration and displacement monitoring in rotating machinery. It converts the physical gap between a proximity probe and a rotating shaft into a precise voltage output, enabling real-time condition monitoring of turbines, compressors, motors, and other critical assets.

This sensor supports both 5 mm and 8 mm proximity probes, providing versatility across different machine configurations. It integrates seamlessly with Bently Nevada 3300 and 9000 monitoring systems and conforms to API 670 standards for advanced machinery protection.

For example, in a gas turbine, the 18745-04 sensor continuously monitors shaft position and vibration levels to prevent failures, reduce downtime, and support predictive maintenance strategies.
