Bently Nevada 330102-27-46-10-02-05 3300 XL 8 mm Proximity Probe

Description

Option 27 (2.7 in unthreaded length) and Option 46 (4.6 in overall case length) specify this armored 3300 XL 8 mm proximity probe configuration — 330102-27-46-10-02-05. This transducer assembly is configured with Option 10 representing a 1.0 m total length, Option 02 for a miniature coaxial ClickLoc connector on standard cable without an additional connector protector, and Option 05 for CSA, ATEX, and IECEx hazardous area approvals.

Unlike standard unarmored variants, the 330102 configuration includes built-in flexible stainless steel armor that covers and protects the standard coaxial cable from physical damage, abrasive wear, and harsh industrial environments. Operating via the eddy-current principle, this probe pairs with a matching 3300 XL extension cable and Proximitor sensor to form a calibrated measuring system, providing reliable shaft vibration, axial position, and rotational speed measurements on critical machinery such as turbines, compressors, generators, and large electric motors.

Features

• Mechanical Protection: Integrated flexible AISI 302/304 stainless steel armor with an outer FEP jacket provides physical guarding over the standard coaxial cable.
• Configured Dimensions: Features a 2.7 in (68.6 mm) unthreaded length and a 4.6 in (116.8 mm) threaded case length with standard 3/8-24 UNF-2A thread.
• Secure Termination: Outfitted with a gold-plated miniature ClickLoc coaxial connector (Option 02) to establish secure high-frequency signal transmission.
• Agency Certifications: Built with Option 05 to meet global requirements for intrinsically safe and non-incendive environments under ATEX, IECEx, and CSA standards.
• Interchangeability: Fully compliant with 3300 XL series standards, allowing direct electrical and physical exchange with same-system components.

Applications

This armored proximity probe is designed for machinery protection and condition monitoring in heavy rotating environments including:

• Steam and gas turbine shaft vibration and position monitoring
• Centrifugal and axial compressor vibration analysis
• Large generator and electric motor bearing clearance measurement
• High-speed industrial pump and gearbox shaft tracking
• Thrust position, radial vibration, and reference keyphasor speed sensing

Installation Guidelines

• Bend Radius Control: Ensure the armored probe lead is routed maintaining a minimum cable bend radius of 25.4 mm (1.0 in) to protect the high-frequency internal coaxial core.
• Thread Torque Limits: When installing the probe body into the threaded mounting port, apply a recommended torque of 11.2 N-m (100 in-lbf). Never exceed the absolute limit of 33.9 N-m (300 in-lbf).
• Connector Mating: Hand-tighten the 3300 XL ClickLoc coaxial connectors. Do not use metal pliers or wrenches on gold-plated connectors, as this can degrade structural plating and lead integrity.
• System Electrical Match: Pair this 1.0 m total length probe with a compatible 3300 XL extension cable (typically 4.0 m or 8.0 m) to ensure the cumulative length meets the required system specifications.

Compliance and Certifications

• Explosion Protection: Fully certified under Option 05 for intrinsic safety, non-incendive environments, and dust protection classifications via CSA, ATEX, and IECEx approvals.
• China Compliance: Standard ATEX/IECEx/CSA certificates are applied. If regional NEPSI or CCC compliance is necessary, the alternative -CN suffix must be requested.
