Bently Nevada 330103-00-05-05-12-05 3300 XL 8 mm Proximity Probe

Description

Option 00 (0 mm unthreaded length), Option 05 (50 mm overall case length), and Option 12 (coaxial ClickLoc connector with FluidLoc cable) define this 3300 XL 8 mm proximity probe configuration — 330103-00-05-05-12-05. This unarmored, metric-threaded (M10 x 1) sensor is used for non-contact eddy-current measurement of shaft vibration and axial position on critical rotating machinery. Featuring a total cable length of 0.5 meters (1.6 feet) and certified under CSA, ATEX, and IECEx approvals (Option 05), this specific variant is optimized for applications requiring oil-barrier protection through its specialized FluidLoc cable, which prevents fluid migration along the interior of the lead.

Unlike variants utilizing standard coaxial cable (such as Option 02) or those featuring stainless steel armor (like the 330104 series), this probe provides direct fluid containment inside the cable sheath, making it ideal for wet or oil-submerged environments where conduit seals are impractical. With a fully threaded case design (0 mm unthreaded), it offers maximum thread engagement flexibility in standard M10 x 1 mounting brackets.

Features

• FluidLoc Cable Technology: Option 12 provides a sealed cable interior that prevents oil and other process liquids from leaking out of the machine housing.
• Fully Threaded Metric Case: Option 00 specifies a 0 mm unthreaded length with a 50 mm overall case length (Option 05) and M10 x 1 threading.
• Miniature ClickLoc Connector: Equipped with a gold-plated coaxial ClickLoc connector for secure, finger-tight connections without requiring special tools.
• Hazardous Area Approval: Option 05 provides compliance with CSA, ATEX, and IECEx safety standards for explosive environments.
• TipLoc Molding: Patented probe tip construction ensures a robust bond between the polyphenylene sulfide (PPS) tip and the stainless steel case.
• CableLoc Design: Delivers up to 330 N (75 lbf) of pull strength to secure the probe cable to the tip.

Applications

• Shaft vibration and axial position measurements on fluid-film bearing machines.
• Steam turbine, gas turbine, compressor, and pump vibration monitoring.
• Machinery protection systems requiring high-pressure or fluid-tight boundary seals.
• Hazardous area machinery installations under ATEX, IECEx, or CSA jurisdictions.

Installation Guidelines

Ensure that the probe case thread engagement does not exceed 15 mm during installation to prevent thread binding or casing damage. Route the FluidLoc cable carefully, maintaining a minimum bend radius of 25.4 mm (1.0 in). Torque the probe case to the recommended value of 11.2 N-m (100 in-lbf) in the mounting bracket, and do not exceed the maximum rated torque of 33.9 N-m (300 in-lbf). Verify that all ClickLoc connections are finger-tight until they click. For hazardous area installations, ensure proper intrinsically safe barrier wiring conforms to the approved installation drawings.
