High-Reliability 50 mm Proximity Probe for Critical Turbomachinery Monitoring
The Bently Nevada 330876-03-90-00-05 3300 XL 50 mm Eddy-Current Proximity Probe is a precision non-contact sensor designed for accurate measurement of shaft displacement, vibration, and differential expansion in large rotating machinery systems. It is part of the 3300 XL 50 mm transducer system, widely used in turbine supervisory instrumentation (TSI) applications across power generation and heavy industry.
This configuration is engineered for harsh operating environments where long cable routing, high temperatures, and electromagnetic interference demand stable and reliable signal performance. It is commonly deployed in steam turbines, compressors, hydro turbines, and generator systems.
