Bently Nevada 330104-01-08-10-01-CN 3300 XL 8 mm Proximity Probe

Product Overview

The 330104-01-08-10-01-CN is a high-precision proximity probe from the Bently Nevada 3300 XL series, the industry standard for machinery condition monitoring. This specific model features an M10 x 1 metric thread and is equipped with stainless steel armor for superior mechanical protection in harsh industrial environments. It is designed to measure static (gap) and dynamic (vibration) distances between the probe tip and a rotating shaft, providing critical data for radial vibration, axial thrust position, and speed measurements on turbines, compressors, and motors. The "CN" designation signifies compliance with country-specific hazardous area approvals, ensuring safe operation in regulated explosive atmospheres.

Technical Configuration

The part number breakdown defines the physical dimensions and electrical interface of the probe:

• M10 x 1 Thread: Metric mounting interface for integration into machine casings or probe housings.

• Unthreaded Length (01): 10 mm of unthreaded tip length, allowing for precise positioning and clearance within the mounting boss.

• Overall Case Length (08): 80 mm total length of the threaded probe body.

• Total Length (10): 1.0 metre (3.3 feet) integrated cable length.

• Connector Type (01): Features the ClickLoc miniature coaxial connector, designed for secure, vibration-resistant coupling, and includes a connector protector.

• Stainless Steel Armor: The cable is encased in a flexible interlocking armor to prevent damage from sharp edges, abrasion, or environmental exposure.

Technical Specifications

Technical FAQs

What is the purpose of the "Connector Protector" included in this model?

The connector protector is a clear sleeve that prevents the ClickLoc connector from loosening due to vibration. It also provides an additional layer of environmental sealing to prevent moisture or oil from entering the coaxial connection point.

Can I connect this 1.0m probe directly to a 9.0m extension cable?

Yes. To maintain the system calibration for a 3300 XL Proximitor, the "Total Length" of the probe plus the extension cable must match the Proximitor’s requirement (typically 5.0m or 9.0m). A 1.0m probe is standard for use with a 4.0m or 8.0m extension cable.

What does the "CN" approval specifically cover?

The "CN" suffix indicates that the probe meets specific national certifications for hazardous areas. For the most accurate and up-to-date regional compliance details, users should refer to the CN Approvals Option Quick Reference Guide provided by the manufacturer.

Engineering & Installation Guide

• Linear Range Alignment: The 3300 XL 8 mm system has a linear range of 2.0 mm (80 mils). For optimal vibration monitoring, the probe should be gapped to the center of this range, typically resulting in a -9.0 VDC output from the Proximitor.

• Armor Handling: While the stainless steel armor is flexible, avoid sharp bends or kinking. The minimum bend radius for armored cables is generally higher than standard cables to prevent internal coaxial damage.

• Tightening Torque: When installing the M10 threads, follow Bently Nevada’s torque specifications to avoid "necking" the probe body. Use a torque wrench and a probe housing for best results.

• Target Material: These probes are calibrated for AISI 4140 steel. If your shaft is made of a different material (e.g., stainless steel or chrome-plated), a custom calibration or scale factor correction may be required in the monitoring system.
