Description：

The Bently Nevada 330101-04-30-05-01-05 is a 3300 XL 8 mm Proximity Probe used for continuous shaft vibration and displacement monitoring in industrial rotating machinery. As a key element of the 3300 XL 8 mm Proximity Transducer System, the probe operates with a compatible extension cable and Proximitor Sensor to deliver precise, non-contact measurements for machinery protection and condition monitoring applications.

The probe is built on the 3300 XL platform, which is recognized for its excellent measurement stability, repeatability, and environmental performance. When integrated into the standard 3300 XL 8 mm 5-meter transducer system, it meets the requirements of API 670 for mechanical configuration, linear operating range, accuracy, and temperature stability. These characteristics make it suitable for machinery protection systems used on high-value rotating assets operating under demanding process conditions.
