Bently Nevada 330101-00-45-15-02-00 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-45-15-02-00 is an unarmored, standard-threaded 8 mm proximity probe designed for high-precision, non-contact machinery vibration and shaft position measurements. As a core component of the Bently Nevada 3300 XL monitoring system, this eddy-current sensor provides outstanding performance and stability in harsh industrial machinery environments. Unlike other configurations in its family that may feature protective armor or metric threads, this specific variant features a standard 3/8-24 UNF thread, a fully threaded 4.5-inch case with 0.0 inches of unthreaded length, and a standard 1.5-meter (4.9 feet) coaxial cable terminated with a miniature coaxial ClickLoc connector.

This proximity probe is ideal for permanent installation on bearing housings and machine casings to monitor steam turbines, gas turbines, compressors, and pumps. It connects seamlessly to a Bently Nevada 330180 series Proximitor sensor via an extension cable to complete the 3300 XL transducer chain, which interfaces directly with 3500 series rack monitoring systems.

Features

• 8 mm tip diameter optimized for non-contact eddy-current displacement and vibration measurements
• Fully threaded 4.5-inch case body without unthreaded sections for rigid and deep mounting setups
• 1.5-meter standard coaxial cable without protective armor, perfect for installations inside protective conduits
• Equipped with a miniature coaxial ClickLoc connector to ensure reliable signal transmission
• Robust Viton O-ring tip-to-case pressure seal preventing leakage of lubrication oils and fluids
• High-stability performance over a wide temperature range for dependable machinery protection

Applications

This 8 mm proximity probe is widely utilized across heavy industrial sectors including power generation, oil and gas, petrochemical processing, and mining. Typical applications include:

• Radial vibration and axial position measurements on high-speed steam and gas turbine shafts
• Rotor displacement monitoring in critical industrial compressors, generators, and pumps
• Permanent mechanical protection and predictive maintenance of rotating machinery bearings

Installation Guidelines

Mount the proximity probe in accordance with standard Bently Nevada procedures. Position the probe tip at the specified gap voltage (typically set per 3300 XL Proximitor requirements at 1.27 mm or 50 mils) to achieve linear displacement scaling. Securely thread the probe casing into the bearing block or bracket. Route the 1.5-meter coaxial cable through protective electrical conduits, avoiding sharp bends, and use proper shielding and grounding practices to ensure maximum immunity against electromagnetic interference (EMI).

Compliance and Certifications

This specific configuration (Agency Approval Option -00) does not require hazardous area approvals. For installations demanding ATEX, IECEx, or CSA certifications, please select sibling configurations with the -05 approval option.
