Bently Nevada 330101-00-52-10-12-05 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-52-10-12-05 is a high-performance 8 mm proximity probe belonging to the industry-standard 3300 XL 8 mm Proximity Transducer System. This specific configuration is engineered for demanding industrial conditions where fluid migration through the sensor cable must be strictly controlled. It features a patented FluidLoc cable option (Option 12), which acts as an internal environmental seal to prevent lubricating oil, water, and other process liquids from leaking out of the machine housing through the core of the coaxial cable.

This non-armored probe is manufactured with a fully threaded 5.2 in case length (0.0 in unthreaded length) and 3/8-24 UNF threads, providing deep-reach capability into machinery bearing housings and casings. Utilizing eddy-current operating principles, it measures static shaft displacement and dynamic vibration without contacting the target surface. It connects to standard 330180 series Proximitor sensors and extension cables, delivering a highly linear output voltage that is directly proportional to the gap between the probe tip and the target. This probe is fully certified under option 05 for use in hazardous areas with CSA, ATEX, and IECEx certifications.

Features

• Eddy-current proximity sensing for precise, non-contact machinery position and vibration monitoring.
• Specialized FluidLoc cable design that blocks oil and liquid leakage through the internal cable structure.
• Extremely rugged polyphenylene sulfide (PPS) probe tip secured with high-strength TipLoc molding.
• Fully threaded 5.2 in overall case length with 0.0 in unthreaded portion for deep casing penetrations.
• Gold-plated miniature ClickLoc coaxial connector that locks securely with finger-tight torque.
• Option 05 hazard approvals, ensuring safety compliance in explosive gas atmospheres.

Applications

• Steam and gas turbine radial shaft vibration monitoring.
• Axial thrust position and casing displacement measurement.
• Submerged oil-filled bearing housings and wet-sump critical pump monitoring.
• Gearbox and reciprocating compressor rotor displacement monitoring.
• API 670 compliant machinery protection systems.

Technical Specifications

Installation Guidelines

• Mount the probe with the appropriate probe gap (nominally -10 Vdc or 1.27 mm / 50 mils gap) per the system calibration parameters.
• Route the FluidLoc coaxial cable with proper shielding and grounding practices to avoid electrostatic interference and cross-talk.
• Do not exceed the maximum thread engagement limit of 0.563 inches for the 3/8-24 UNF threads to prevent binding.
• Keep the miniature ClickLoc connector clean, dry, and free of lubricants. Hand-tighten until a positive click is felt.

Compliance and Certifications

• CSA Certified for hazardous areas (Class I, Division 1, Groups A, B, C, D)
• ATEX and IECEx Certified for Zone 0, Zone 1, and Zone 2 explosive environments (Ex ia IIC)
• CE Compliant
