High-Stability Signal Conditioning for Critical Turbomachinery Monitoring
The Bently Nevada 330878-51-05 3300 XL Proximitor Sensor is a precision signal conditioning module designed for use in the 3300 XL 50 mm proximity transducer system. It converts raw eddy-current probe signals into stable, linear electrical outputs used for continuous monitoring of shaft vibration, displacement, and differential expansion in large rotating machinery.
This Proximitor® unit is widely deployed in turbine supervisory instrumentation (TSI) systems, where long-term stability, low noise performance, and high electromagnetic immunity are essential for reliable machinery protection. It is engineered for continuous industrial service in demanding environments such as power plants and heavy industrial facilities.
