Bently Nevada 330101-00-25-05-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

330101-00-25-05-02-CN is a Bently Nevada 3300 XL 8 mm proximity probe designed for precise shaft vibration and displacement measurement in critical rotating machinery systems. This 330101-00-25-05-02-CN (330101-00-25-05-02-CN) is widely used in turbines, compressors, pumps, and generators across oil refineries, power plants, and heavy industrial facilities. It delivers stable eddy current signals for continuous condition monitoring and early fault detection. The probe supports maintenance teams in identifying imbalance, misalignment, and bearing wear before failure occurs. Its compact design and stainless steel construction ensure reliable performance under high vibration and temperature stress, helping reduce unplanned downtime and improve asset availability.

Suffix Breakdown

The model structure defines mechanical and electrical configuration:

• 00 = Unthreaded length 0.0 in

• 25 = Overall case length 2.5 in

• 05 = Total probe length 0.5 metre (1.6 feet)

• 02 = Miniature coaxial ClickLoc connector with standard cable

• CN = China-specific hazardous area approvals including NEPSI, CCC, and ATEX IECEx compliance

This configuration ensures correct mounting geometry, electrical connectivity, and regulatory compliance for industrial environments.

Technical Specifications

Technical FAQs

Is this probe compatible with 3300 XL monitoring systems?
Yes. It is fully compatible with Bently Nevada 3300 XL proximitor and monitoring modules.

What does the CN suffix indicate?
It indicates China-specific hazardous area certification including NEPSI, CCC, and ATEX IECEx compliance.

What happens if the probe gap is incorrect?
