High-Temperature Eddy-Current Probe for Critical Shaft Position Monitoring
The Bently Nevada 330876-02-50-01-00 3300 XL 50 mm Proximity Probe is a high-performance eddy-current sensor designed for precise measurement of shaft vibration, radial position, and displacement in large rotating machinery.
As part of the 3300 XL 50 mm proximity transducer system, this probe is engineered for demanding environments such as steam turbines and large compressors where high temperature stability, long-term signal accuracy, and moisture resistance are essential. The system is commonly used in critical machinery protection and condition monitoring applications in power generation and heavy industry.
This configuration is typically paired with a matching 3300 XL Proximitor® sensor and extension cable to form a complete measurement chain.
