Bently 330709-000-050-10-02-00 3300 XL 11mm Proximity Probe

Advanced Proximity Probe for High-Precision Vibration and Displacement Measurements

The Bently Nevada 330709-000-050-10-02-00 is part of the 3300 XL 11 mm Proximity Transducer System, specifically designed to provide precise vibration, displacement, and axial position measurements in rotating machinery. This system includes the 3300 XL 11 mm probe, extension cable, and Proximitor Sensor. These components work together to offer reliable and accurate data for critical machine monitoring.

The system features a 3.94 V/mm (100 mV/mil) output, allowing it to deliver non-contacting vibration and displacement measurements on fluid film bearing machines. With its 11 mm tip, this transducer system achieves a longer linear measurement range compared to the standard 3300 XL 8 mm Transducer System. As a result, it is ideal for applications where extended measurement ranges are required, such as:

Axial (thrust) position measurements
Ramp differential expansion on steam turbines
Rod position or rod drop measurements in reciprocating compressors
Tachometer and zero speed measurements
Phase reference (Keyphasor) signals

The 3300 XL 11 mm Proximitor Sensor is designed to replace the older 7200-series 11 mm and 14 mm Transducer Systems. When upgrading, it is important to replace all components with the 3300 XL 11 mm parts and update the monitoring system. If you are using a 3500 Monitoring System, an updated version of the configuration software is necessary to support the 3300 XL 11 mm system.
