330101-00-28-20-02-CN | Bently Nevada | 3300 XL 8 mm Proximity Probe

Product Overview

330101-00-28-20-02-CN  is a Bently Nevada 3300 XL 8 mm proximity probe designed for high-precision shaft vibration and position monitoring in critical rotating machinery. It is widely deployed in turbines, compressors, generators, and refinery process equipment where continuous condition monitoring is required to prevent mechanical failure and unplanned downtime.

This probe operates as part of the Bently Nevada 3300 XL transducer system and delivers stable eddy-current measurement performance under high vibration and industrial noise conditions. The system architecture supports accurate gap voltage measurement and reliable shaft displacement tracking, which is essential for predictive maintenance programs in power generation and heavy process industries.

The CN suffix configuration includes China-specific approval compliance, ensuring deployment flexibility in regulated industrial environments. The 2.0 m total cable length and ClickLoc connector system provide secure mechanical locking and reduce signal loss at the interface point, improving long-term operational stability.

Suffix Breakdown and Configuration Logic

The configuration defines mechanical form factor, connector type, and compliance classification. The probe body design supports installation into 3/8-24 UNF threaded housings without armor protection.

Technical Specifications

Technical FAQs

Is this probe compatible with all 3300 XL extension cables?
Yes. It is designed for full compatibility with Bently Nevada 3300 XL extension and Proximitor systems.

What is the advantage of ClickLoc connectors?
ClickLoc connectors provide secure mechanical locking and reduce signal noise caused by loose connections.

Can this probe be used in high-temperature turbine environments?
Yes. It supports up to 177 deg C operating temperature when installed within approved system limits.

Does the CN suffix affect performance?
No. The CN suffix relates to regional compliance approvals, not measurement performance.

Engineering & Installation Guide

Maintain a stable probe gap during installation. Incorrect gap settings directly affect voltage output accuracy and vibration readings.

Route probe cables away from high-voltage conductors and VFD output lines. This reduces EMI-induced signal distortion in monitoring systems.

Use proper torque when installing into 3/8-24 UNF threads. Over-tightening can deform the probe housing and affect alignment stability.
