Bently Nevada 330103-00-04-05-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

The 330103-00-04-05-02-CN 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 equipment. Industrial facilities in refining, LNG processing, power generation, and petrochemical production widely deploy this probe within machinery protection systems where stable vibration data directly affects operational reliability and shutdown prevention.

This probe belongs to the 3300 XL transducer system and supports accurate signal transmission in demanding industrial environments with high vibration, oil exposure, and temperature fluctuation. The compact 40 mm probe body simplifies installation inside restricted bearing housings and turbine assemblies. The ClickLoc miniature coaxial connector improves cable retention reliability under continuous machine vibration conditions. The CN approval option supports hazardous area installations requiring NEPSI, CCC, and applicable ATEX/IECEx compliance for explosive gas and dust environments.

Technical Specifications

Technical FAQs

What does the CN approval option indicate?

The CN suffix identifies the China hazardous area approval package. It covers applicable NEPSI and CCC requirements and includes ATEX/IECEx hazardous area markings for explosive gas and dust environments.

Can this probe operate with standard 3300 XL Proximitor sensors?

Yes. The probe is designed for direct integration with compatible 3300 XL Proximitor sensors and extension cables using matched electrical lengths.

Why is the ClickLoc connector important in turbine applications?

The ClickLoc connector improves cable retention and reduces loosening risks caused by long-term vibration exposure in turbine and compressor systems.

Can this probe replace older Bently Nevada proximity probes?

Replacement compatibility depends on probe length, thread configuration, electrical length, and monitoring system calibration requirements.

Engineering & Installation Guide

Maintain the recommended probe target gap voltage during commissioning. Incorrect gap adjustment may reduce measurement linearity and vibration accuracy.

Separate probe cables from motor power wiring and variable frequency drive output cables. Proper routing reduces electromagnetic interference inside machinery protection cabinets.

Avoid excessive installation torque on the M10 x 1 threaded body. Over-tightening may damage the probe housing or affect long-term measurement stability in high-vibration environments.
