Description

Fully threaded 3/8-24 UNF steel probe body (Option 00) with 1.5 in overall case length (Option 15) and 1.0 m total length (Option 10) defines the configuration for this Bently Nevada 3300 XL 8 mm proximity probe — 330101-00-15-10-02-05.

Unlike armored configurations (such as the 330102 series) or models with integrated connector protectors (Option 01), this unarmored configuration features standard coaxial cable and a bare miniature coaxial ClickLoc connector (Option 02). Calibrated to a nominal linear range of 2.0 mm (80 mils), this eddy-current sensor operates within standard Bently Nevada 3300 XL monitoring systems to track shaft vibration, axial position, and radial displacement on critical rotating machinery bearing housings.

Features

• Option 00 specifies a 0.0 in (0.0 mm) unthreaded length, making the entire 1.5 in casing fully threaded for flexible mounting adjustment.
• Option 15 provides a 1.5 in overall case length with standard 3/8-24 UNF threads.
• Option 10 defines a 1.0 meter (3.3 feet) total cable length, matching specific distance and configuration constraints.
• Option 02 equips the probe with a miniature coaxial ClickLoc connector on standard unarmored coaxial cable.
• Option 05 provides approvals including CSA, ATEX, and IECEx for hazardous area installations.
• Non-contact eddy-current measurement principle is impervious to oil, water, and steam contamination at the probe tip.

Applications

• Steam turbine shaft radial vibration and axial thrust position measurements.
• Gas turbine rotor displacement and casing expansion monitoring.
• Centrifugal compressor and multi-stage pump rotor dynamics and bearing clearance checks.
• Permanent machine casing and bearing housing vibration monitoring in hazardous industrial environments.

Installation Guidelines

• Mount the probe with the appropriate probe gap (nominally 1.27 mm or 50 mils) per system calibration requirements.
• Ensure proper routing of the standard unarmored coaxial cable through protective conduits to prevent wear or mechanical abrasion.
• Adhere to a maximum thread engagement limit of 0.563 in to prevent binding within the bearing housing threads during installation.
• Use proper shielding and grounding practices across the transducer system to minimize electromagnetic interference.
• Tighten standard ClickLoc connectors to finger-tight specifications to secure the coaxial signal path.

Compliance and Certifications

• CSA, ATEX, and IECEx approvals for use in hazardous areas (Option 05)
• Ex ia IIC T5...T1 Ga (for intrinsically safe gas atmospheres)
• Ex ia IIIC T90degC...T280degC Dc (for intrinsically safe dust atmospheres)
