Bently Nevada 330103-00-19-10-12-05 3300 XL 8 mm Proximity Probe

Description

Option 00 (0 mm unthreaded length), Option 19 (190 mm overall case length), and Option 12 (FluidLoc cable with Miniature ClickLoc connector) specify this 3300 XL 8 mm proximity probe configuration — 330103-00-19-10-12-05. This unarmored probe operates on eddy-current technology to track shaft vibration and axial position. It features a metric M10 x 1 threaded body, a 1.0 m total cable length (Option 10), and carries CSA, ATEX, and IECEx hazardous area certifications (Option 05) for intrinsically safe installations.

Unlike standard coaxial cables, the integrated FluidLoc cable (Option 12) prevents lubricating oil, turbine fluids, or other process liquids from leaking out of the machine housing through the inner layers of the cable. The fully threaded case (0 mm unthreaded portion) provides robust mounting engagement inside deep-reach threaded bores, making it ideal for large turbine and compressor bearing casings where standard unthreaded neck lengths are unsuitable.

Features

• FluidLoc cable (Option 12) prevents process fluids and turbine oil from migrating through the internal cable core.
• Fully threaded case design (Option 00) with 0 mm unthreaded length for maximum structural mount engagement.
• Metric M10 x 1 threaded brass casing (without armor) providing a robust 190 mm overall case length (Option 19).
• Gold-plated coaxial ClickLoc connector provides secure finger-tight connection with an audible lock, eliminating specialized assembly tools.
• 1.0 meter total cable length (Option 10) connects to 3300 XL standard extension cables in 5-meter or 9-meter transducer systems.
• Hazardous area approvals (Option 05) certified under CSA, ATEX, and IECEx standards for Zone 0, Zone 1, and Division 1 environments.

Applications

This proximity probe is used in critical rotating machinery protection systems. Typical applications include radial shaft vibration, axial thrust position, and reference speed/keyphase measurements on steam turbines, gas compressors, industrial pumps, and electrical generators, specifically in bearings or environments where fluid containment is critical.

Installation Guidelines

• Maintain a minimum target size of 15.2 mm (0.6 in) flat target diameter.
• Recommended target shaft diameter must be 76.2 mm (3.0 in) or larger to avoid change in scale factor.
• Avoid cross-talk by maintaining a minimum separation of 40 mm (1.6 in) for axial position or 38 mm (1.5 in) for radial vibration measurements.
• Do not exceed 15 mm thread engagement during installation to prevent thread binding in the mounting bore.
• Ensure probe gap is set within the 3300 XL Proximitor sensor's linear calibration range prior to final tightening of locking nuts.
