Bently Nevada 330101-00-20-90-02-00 3300 XL 8 mm Proximity Probe

Product Overview

The 330101-00-20-90-02-00 3300 XL 8 mm proximity probe from Bently Nevada provides continuous shaft vibration and radial position monitoring for turbines, compressors, pumps, and other critical rotating machinery. It is widely used in power generation, oil and gas refining, LNG processing, and petrochemical plants where reliable machinery protection directly impacts plant availability and operational safety.

This probe is part of the 3300 XL proximity measurement system and delivers stable signal performance in high vibration and harsh industrial environments. The 2.0 in case length design supports standard mounting configurations, while the 9.0 m cable length allows flexible routing in large machinery installations. The miniature coaxial ClickLoc connector improves connection stability under continuous vibration conditions. The 3/8-24 UNF threaded design ensures secure mechanical installation on rotating equipment housings. This configuration supports accurate condition monitoring and helps reduce unplanned downtime by enabling early detection of mechanical faults.

Technical FAQs

Is this probe compatible with all 3300 XL systems?

Yes. It is designed for use with Bently Nevada 3300 XL monitoring systems when electrical length matching is properly configured.

What is the advantage of the ClickLoc connector?

The ClickLoc connector improves mechanical locking strength and reduces signal interruption caused by vibration in rotating machinery environments.

Can this probe be used in turbine monitoring applications?

Yes. It is commonly used for turbine, compressor, and pump shaft vibration monitoring in industrial protection systems.

Does cable length affect measurement accuracy?

Yes. Proper system matching between probe, extension cable, and Proximitor sensor is required for accurate calibration and signal stability.

Engineering & Installation Guide

Maintain correct probe gap voltage during installation to ensure linear measurement performance. Incorrect gap settings may affect vibration signal accuracy.

Route probe cables away from high-voltage cables and variable frequency drives to reduce electromagnetic interference in monitoring systems.

Secure cable routing inside machine housings using vibration-resistant clamps. Loose routing may lead to connector fatigue in long-term operation.
