Product Overview

The Bently Nevada 330101-00-20-10-02-00 is a high-precision eddy current proximity probe, serving as a fundamental component of the 3300 XL Transducer System. This non-contacting sensor is engineered to measure both the static position and dynamic vibration of a target surface, typically a rotating shaft. By providing high-resolution displacement data, it enables the monitoring of fluid-film bearing machines, thrust position, and speed detection. The probe is designed to withstand the harsh environments found in power plants and refineries, offering superior thermal stability and complete interchangeability with other 3300 XL components without the need for individual calibration.

Industrial Applications and Operational Use Cases

The 330101-00-20-10-02-00 probe is a versatile solution for Original Equipment Manufacturers (OEMs) and end-users monitoring critical rotating assets.

• Radial Vibration Monitoring Essential for identifying rotor unbalance, misalignment, and mechanical looseness by tracking shaft orbits within bearings.

• Axial Position (Thrust) Sensing Used to measure the axial movement of shafts to prevent rotor-to-stator contact in turbines and compressors.

• Keyphasor Reference Providing once-per-turn timing signals for phase-related vibration diagnostics and speed measurements.

• High-Temperature Zones Reliable operation in bearing housings where temperatures fluctuate significantly, thanks to the patented TipLoc molding process.

• TSI Integration Fully compatible with Bently Nevada 3500 and 1900 series monitoring racks for automated alarm and shutdown logic.

The inclusion of the ClickLoc connector ensures a secure, vibration-resistant electrical path, while the lack of armor allows for easier routing through conduit or tight internal machinery spaces.
