Bently Nevada 330104-05-17-10-11-05 3300 XL 8 mm Proximity Probe

Description

330104-05-17-10-11-05 specifies a Bently Nevada 3300 XL 8 mm proximity probe with an M10 x 1 metric thread and flexible stainless steel armor. This configuration is distinguished by its 50 mm unthreaded length (Option 05) and 170 mm overall case length (Option 17), providing mechanical clearance for deeper thread-in bearing housings. It features a 1.0-meter total length (Option 10) terminated in a miniature coaxial ClickLoc connector with an integrated connector protector and FluidLoc cable (Option 11).

The flexible metal armor, constructed from AISI 302/304 stainless steel with a FEP outer jacket, safeguards the triaxial cable from physical shear and wear. The FluidLoc cable core prevents lubrication oils and process fluids from leaking out of the machine along the interior of the cable, while the integrated connector protector shields the gold-plated click connection from fluid ingress. This probe is certified under Option 05 for CSA, ATEX, and IECEx hazardous areas and integrates into standard eddy-current monitoring chains to observe shaft vibration, axial position, and speed in industrial rotating machinery.

Features

• Metric M10 x 1 Threaded Body: Made from AISI 303/304 stainless steel, with a 170 mm case length and 50 mm unthreaded clearance.
• Flexible Stainless Steel Armor: Protected by flexible AISI 302/304 metal armor with a FEP jacket to withstand harsh physical environments.
• FluidLoc Oil Barrier: Built with FluidLoc cable technology that prevents lubricating oils or gases from migrating along the cable core.
• Integrated Connector Protector: Features a robust polymer sleeve that shields the miniature coaxial ClickLoc connection from oil and moisture.
• ClickLoc Coaxial Connection: Gold-plated brass and beryllium copper contacts ensure stable electrical signal transmission.
• Hazardous Location Certification: Pre-approved under Option 05 with CSA, ATEX, and IECEx safety standards.

Applications

Designed for heavy industrial machinery protection across petrochemical, power generation, and refining sectors. Primary installations include:

• Steam turbine rotor position and radial vibration monitoring.
• Submerged or oil-sprayed bearings inside high-speed centrifugal compressors.
• Thrust displacement and vibration tracking on industrial gearboxes.
• Large industrial pumps operated in hazardous or corrosive environments.

Installation Guidelines

To preserve accuracy and avoid damaging the 3300 XL system during installation:

• Ensure the probe target matches standard AISI 4140 steel calibration for linear measurement scaling.
• Observe the maximum thread engagement limit of 15 mm for M10 x 1 metric threads to prevent thread binding.
• Maintain the minimum cable bend radius of 25.4 mm (1.0 in) to prevent internal electrical shorting or signal attenuation.
• Connect ClickLoc interfaces finger-tight, then deploy the integrated connector protector sleeve to shield the junction against oil contamination.

Compliance and Certifications

• CSA: Approved for Class I, Division 1 and Division 2 hazardous locations.
• ATEX/IECEx: Certified intrinsically safe and non-sparking for Zone 0, Zone 1, and Zone 2 gas atmospheres.
