Product Description

Description

Fully threaded 3/8-24 UNF steel probe body (Option 00) with 8.4 in case (Option 84) and 2.0 m lead (Option 20) — 330101-00-84-20-02-05. This 3300 XL 8 mm proximity probe configuration features a miniature coaxial ClickLoc connector on standard unarmored coaxial cable (Option 02) and includes hazardous area approvals (Option 05) such as CSA, ATEX, and IECEx.

This unarmored variant operates on the eddy-current principle to provide non-contact displacement measurements. It is used in Bently Nevada 3300 XL transducer systems to monitor parameters such as shaft vibration, axial position, and rotor displacement on critical rotating machinery. The probe connects to a 3300 XL extension cable and 330180 series Proximitor sensor, outputting a continuous voltage signal proportional to the physical gap between the probe tip and the target material.

Features

Option 00 unthreaded length: 0.0 in (fully threaded probe body).
Option 84 overall case length: 8.4 in.
Option 20 total cable length: 2.0 m (6.6 ft).
Option 02 cable type: Standard coaxial cable with miniature coaxial ClickLoc connector.
Option 05 agency approvals: CSA, ATEX, and IECEx.
PPS (polyphenylene sulfide) probe tip is molded to encapsulate the sensor coil, resisting harsh industrial chemical environments.
Stainless steel probe body is suitable for permanent mounting in bearing housings or machine casings.

Applications

Steam and gas turbine shaft vibration and position monitoring
Compressor and pump rotor displacement measurements
Permanent machine protection on fluid-film bearing housings
Critical rotating machinery axial position and radial vibration monitoring

Installation Guidelines

Mount the probe securely using the 3/8-24 UNF thread; ensure thread engagement does not exceed 0.563 in to prevent binding.
Verify the probe gap using a digital voltmeter or gap-measuring tool to target -9 Vdc at the recommended physical gap.
Ensure the minimum side-view clearance from adjacent metal is respected to prevent electrical cross-talk or measurement error.
Route the standard unarmored coaxial cable using proper shielding, routing, and grounding practices typical of machinery monitoring networks.
Ensure the total electrical length of probe and extension cable matches the calibrated length of the 3300 XL Proximitor sensor (typically 5 m or 9 m).
