Bently Nevada 330101-00-70-10-02-00 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-70-10-02-00 is a specialized, fully threaded configuration of the 3300 XL 8 mm Proximity Probe, offering a 7.0-inch overall case length (0.0-inch unthreaded length) and an integrated 1.0-meter coaxial cable terminated with a miniature ClickLoc connector. Designed specifically for critical machine installations where hazardous area approvals are not required, this unarmored variant allows for extensive mechanical depth adjustability along its entire threaded body. When integrated into a standard 3300 XL monitoring chain with a compatible Proximitor sensor and extension cable, it provides highly precise, non-contact measurements of radial shaft vibration and axial thrust position to prevent sudden machinery failures.

Features

• Fully threaded 7.0-inch case body (3/8-24 UNF thread) without unthreaded sections, providing maximum depth adjustability in dense machine casings.
• Robust 8 mm probe tip diameter designed to survive hot, oily bearing housing environments.
• Integrated 1.0-meter (3.3 feet) standard coaxial cable for clean electrical signal path with low attenuation.
• Miniature male ClickLoc coaxial connector for secure, click-to-lock connection with matching extension cables.
• Reliable eddy-current measurement principle for non-contact, high-frequency static and dynamic displacement sensing.

Applications

This Bently Nevada proximity probe is engineered for continuous condition monitoring and machinery protection in heavy industrial applications, including:

• Radial vibration and shaft position monitoring on high-speed steam and gas turbines.
• Axial thrust displacement sensing in industrial centrifugal compressors, turboexpanders, and gearboxes.
• General rotating machinery protection systems where non-hazardous operating conditions exist and external armor protection is not required.

Installation Guidelines

• Mounting Alignment: Carefully thread the probe into its bracket or port. Ensure that you do not exceed the maximum installation torque rating of 13.5 N-m (120 in-lb) to prevent thread deformation.
• Probe Gap Target: Adjust the gap physically until the DC output voltage of the Proximitor sensor reads approximately -9.0 Vdc (which corresponds to a 1.27 mm or 50 mils gap) for radial vibration monitoring.
• Cable Protection: Keep the integrated coaxial cable clear of sharp metal edges. Maintain a minimum bend radius of 25.4 mm (1.0 in) to prevent internal shield fatigue.
• Connector Cleanliness: Ensure ClickLoc coaxial connectors are completely free of dirt, oil, and moisture before mating. Use self-coalescing silicone tape to seal connections if exposed to continuous oil mist.
