Description

Option 00 (0.0 in unthreaded length), Option 40 (4.0 in overall case length), Option 20 (2.0 m total length), Option 12 (coaxial ClickLoc connector with FluidLoc cable), and Option 05 (CSA, ATEX, and IECEx approvals) define this specific 3300 XL 8 mm Proximity Probe configuration — 330101-00-40-20-12-05.

This eddy-current proximity sensor tracks static and dynamic displacement of rotating machinery components. Unlike standard coaxial models or armored options (such as the 330102 series), this configuration includes a specialized FluidLoc cable. The FluidLoc jacket blocks lubricating oils and other process liquids from leaking along the internal paths of the coaxial cable, maintaining containment integrity. The probe features a fully threaded 3/8-24 UNF steel casing, designed to mount permanently into machine casings or bearing housings, and works directly with a 3300 XL Proximitor sensor and extension cable.

Features

• Option 00 specifies a fully threaded 3/8-24 UNF steel body with 0.0 in of unthreaded length.
• Option 40 provides a 4.0 in (101.6 mm) overall case length.
• Option 20 provides a 2.0-meter (6.6-foot) total cable length.
• Option 12 features a FluidLoc coaxial cable to stop oil and fluid migration along the cable interior.
• Option 05 offers CSA, ATEX, and IECEx agency certifications for explosion-proof and intrinsically safe environments.
• Non-contacting eddy-current technology prevents physical wear during shaft position and vibration measurements.
• Terminated with a miniature coaxial ClickLoc connector for secure click-lock connectivity.

Applications

• Steam and gas turbine shaft vibration and axial position measurements.
• Compressor and pump rotor dynamic displacement and thermal expansion tracking.
• Fluid-film bearing performance monitoring in critical heavy-industry rotating assets.
• Permanent mounting in bearing housings and machine casings where oil-tight cable pathways are required.

Installation Guidelines

• Establish the appropriate probe gap during physical installation, typically set to -9 Vdc (approximately 1.27 mm or 50 mils) from the shaft target for radial vibration tracking.
• Ensure the unthreaded length is selected properly relative to the bearing housing wall thickness to prevent probe tip or housing threads from sustaining mechanical damage.
• Maintain standard vibration monitoring cable routing guidelines, using recommended shielding and single-point grounding methods to minimize signal noise.
• Do not bend the FluidLoc coaxial cable past its specified minimum bend radius during deployment.
• Verify that the male ClickLoc coaxial connector clicks firmly into place with the extension cable.
