The Bently Nevada 330104-00-08-50-12-00 Proximity Probe Module is a high-performance non-contact eddy-current sensor engineered for precise measurement of shaft vibration, radial displacement, shaft position, and rotor movement in industrial rotating equipment. As a member of the globally trusted 3300 XL 8 mm Proximity Transducer System, this probe delivers exceptional measurement accuracy, long-term reliability, and stable operation in some of the most demanding industrial environments.
This configuration combines an 80 mm probe case length (Option 08), an extended 5.0-meter system length (Option 50), an Option 12 enhanced connector configuration, and a standard industrial approval package (00). Designed for installations requiring extended cable routing and specialized connection arrangements, the module provides an ideal solution for complex machinery monitoring systems where installation flexibility and signal integrity are equally important.
From large steam turbines and gas compressors to generators and process pumps, the 330104-00-08-50-12-00 helps maintenance teams gain real-time visibility into machine health while supporting predictive maintenance strategies that reduce downtime and maintenance costs.
