Bently Nevada 330101-00-35-10-11-05 3300 XL 8 mm Proximity Probe

Description

For specialized machinery protection within critical turbine and compressor bearing housings, the Bently Nevada 330101-00-35-10-11-05 provides highly reliable, non-contact shaft vibration and position monitoring. This 8 mm proximity probe is designed for the 3300 XL Proximity Transducer System and is configured with a fully threaded 3.5-inch case, a 1.0-meter FluidLoc cable, and a gold-plated ClickLoc connector with a pre-installed connector protector.

Unlike standard configurations, this unit integrates the patented FluidLoc design, which blocks oil, process fluids, and other hazardous liquids from migrating through the cable's internal structure. It also includes integrated connector protection to guard against moisture and mechanical damage in harsh bearing housing environments, backed by comprehensive CSA, ATEX, and IECEx hazardous area approvals.

Features

• Fully Threaded Body: Features a 3.5-inch (89 mm) overall case length with 0.0 inches (0 mm) of unthreaded length, allowing maximum adjustment within 3/8-24 UNF threaded mounting ports.
• FluidLoc Cable Technology: Specially engineered internal sealing prevents lubricating oils, water, and process gases from leaking out of the machine housing through the cable interior.
• ClickLoc Connector with Protector: Equipped with a miniature coaxial ClickLoc gold-plated connector featuring a pre-installed protective sleeve to seal out dirt, grease, and moisture.
• Robust Construction: Utilizes Bently Nevada's TipLoc molding for an extremely durable bond between the PPS (polyphenylene sulfide) probe tip and the stainless steel body.
• High Pull Strength: Incorporates the CableLoc design, offering up to 330 N (75 lbf) of pull strength to withstand pulling forces during installation and routing.
• Standard 1.0-Meter Length: Integrates a 1.0-meter (3.3 feet) cable, perfect for routing directly to an extension cable and Proximitor sensor chain.

Applications

• Turbine Shaft Vibration & Position Monitoring: Captures dynamic vibration and axial position of fluid-film bearings in steam and gas turbines.
• High-Pressure Process Machinery: Ideal for compressors, pumps, and gearboxes where keeping process fluids or bearing oil contained within the housing is critical (utilizing FluidLoc technology).
• Hazardous Area Machinery Protection: Suitable for petrochemical plants and oil platforms requiring explosion-proof or intrinsically safe monitoring systems.
• Retrofitting & Maintenance: Directly replaces older 3300 series 8 mm or 5 mm probes, maintaining full backward compatibility.

Installation Guidelines

• Mount with the appropriate probe gap to match the linear range of the 3300 XL system (typically calibrated for a 2.0 mm/80 mils range).
• Ensure the coaxial cable is routed with proper shielding and grounding to prevent electromagnetic interference from machinery.
• Avoid exceeding the maximum thread engagement limit of 0.563 inches for 3/8-24 UNF threads to prevent binding.
• Finger-tighten the miniature coaxial ClickLoc connector until it clicks; do not use excessive force or tools on the gold-plated connector unless mating with a non-XL steel connector.

Compliance and Certifications

• CSA: Intrinsically Safe and Non-Incendive certifications.
• ATEX: Certified for use in Category 1 and Category 2 hazardous environments.
• IECEx: Global hazardous area certification compliance.
