Product Introduction
The 330850-91-00 25 mm Proximitor Sensor is a high-performance non-contact displacement transducer designed for long-range position and vibration monitoring. As part of the Bently Nevada 3300 series measurement chain, this proximitor converts probe gap changes into a precise voltage signal, enabling accurate shaft vibration, axial position, and displacement readings on large rotating machinery.
With a 25 mm linear measurement range, the 330850-91-00 is ideal for applications requiring extended sensing distance or monitoring of large shaft diameters. Its rugged electronics housing ensures stable operation under demanding industrial conditions, including high temperatures, mechanical vibration, and electrically noisy environments.
This proximitor is widely used in turbines, compressors, hydro units, and critical rotating equipment requiring reliable displacement feedback.
