Product Introduction
The Bently Nevada 330851-02-000-030-50-00-00 3300 XL 25 mm Proximity Probe is a high-precision, non-contact displacement sensor developed for continuous condition monitoring of large rotating machinery. As part of the 3300 XL series, this probe is engineered to deliver stable, accurate measurements in demanding industrial environments.
The 25 mm probe size is specifically intended for applications requiring extended measurement range and higher tolerance to shaft movement, making it well suited for heavy-duty equipment. With a total length of 5.0 meters, the probe provides installation flexibility while maintaining reliable signal transmission. Its robust construction ensures long-term stability and repeatability in critical monitoring systems.
This model is commonly deployed in turbine, compressor, and large motor monitoring systems where accurate shaft position and vibration data are essential for machinery protection and predictive maintenance.
