Product Overview

The Bently Nevada 330106-05-30-20-02-00 is a 3300 XL 8 mm eddy-current proximity probe used for non-contact measurement of shaft vibration and shaft position on rotating machinery. When installed as part of a complete proximity transducer system (probe + extension cable + Proximitor sensor), it provides a stable displacement signal for machinery protection, condition monitoring, and TSI (Turbine Supervisory Instrumentation) functions.

This probe is typically mounted at machine bearings or thrust locations to observe dynamic shaft motion relative to the bearing housing. Accurate displacement feedback supports early detection of developing mechanical problems such as unbalance, misalignment, rubs, oil whirl/whip, and bearing deterioration.

Hardware Parameters

• Model / Order Code: 330106-05-30-20-02-00

• Product Family: 3300 XL 8 mm Proximity Transducer System

• Product Type: Eddy-current proximity probe (8 mm class)

• Measurement Function: Shaft radial vibration and/or position (application dependent)

• System Components Required: Matching 3300 XL extension cable and 3300 XL Proximitor sensor (calibration depends on total system length)

• Installation: Threaded probe body mounting, gap setting per machinery standards (typical for proximity probes)

• Output Interface: Signal is conditioned/powered by the Proximitor sensor; probe is not a standalone powered device

• Environment: Designed for industrial rotating equipment installations with long-term stability requirements

Engineering notes

• “330106” is associated with 3300 XL 8 mm probe families; however, the detailed option string (-05-30-20-02-00) defines mechanical and ordering variants. Confirm probe length, connector style, and any armor or agency options required for the site.

• Probe performance depends on correct target material, probe gap, and matched system calibration with the extension cable and Proximitor.

Industrial Applications

Common use cases include:

• Steam and gas turbines for bearing vibration monitoring and rotor behavior trending

• Centrifugal compressors for continuous displacement measurement supporting protection and reliability programs

• Critical pumps and motor-driven trains where early vibration change reduces seal and bearing risk

• Gearboxes and high-speed machinery where non-contact sensing improves survivability versus contacting sensors

• Retrofit projects where legacy probes are replaced while maintaining proximity-based monitoring architecture (subject to compatibility checks)

Installation considerations

• Verify mechanical clearances and maintain recommended gap to avoid signal saturation

• Route transducer wiring using proper shielding and grounding practices to reduce EMI sensitivity

• Perform channel verification after installation to confirm stable “OK” condition and correct scaling in the monitor/controller
