Bently Nevada 330101-00-10-10-12-05 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-10-10-12-05 is a 3300 XL 8 mm eddy-current proximity probe used for non-contact shaft vibration and displacement monitoring in critical rotating machinery. This specific configuration features a 1.0-inch fully threaded 3/8-24 UNF body with zero unthreaded length, optimized for flush-mounting within tight clearances on bearing housings or casings.

This model integrates a 1.0-meter (3.3-foot) lead cable with patented FluidLoc® technology (Option 12) to prevent lubricating oil or process fluids from leaking through the cable core. The cable terminates in a gold-plated miniature coaxial ClickLoc™ connector. Additionally, the assembly includes Option 05 hazardous area approvals, certifying it for use in international explosion-proof and intrinsically safe installations.

Features

• 8 mm eddy-current sensor tip calibrated for non-contact displacement and dynamic vibration measurements.
• FluidLoc® cable construction prevents process fluid migration and weeping through the cable interior.
• TipLoc™ molding provides a high-strength bond between the polymer probe tip and the stainless steel body.
• CableLoc™ internal strain relief provides up to 330 N (75 lbf) of cable pull strength.
• Gold-plated ClickLoc™ coaxial connector locks with an audible click and requires no tooling.
• Standard 3/8-24 UNF-2A threaded stainless steel body (unarmored).
• Option 05 agency approval for CSA, ATEX, and IECEx hazardous areas.
• Fully interchangeable with standard 3300 XL Proximitor® sensors (330180 series) and extension cables.

Applications

• Radial shaft vibration and rotor dynamics analysis on steam and gas turbines.
• Thrust and axial displacement monitoring in high-speed compressors, pumps, and fans.
• Shaft motion and runout monitoring on hydroelectric generators.
• High-pressure bearing housings requiring reliable fluid containment along sensor runs.
• API 670 machinery protection systems in power generation, petrochemical, and oil and gas facilities.

Installation Guidelines

Mount the probe at the target system's calibrated gap, typically 1.27 mm (50 mils) for AISI 4140 steel. Ensure mounting threads are clean and free of burrs. Follow standard industrial shielding and grounding practices during cable routing to prevent EMI/RFI noise. Hand-tighten the ClickLoc™ connectors until an audible click is achieved. Maintain the minimum specified cable bend radius to protect the coaxial core from degradation.

Compliance and Certifications

This probe is certified for hazardous locations under Option 05 (CSA, ATEX, IECEx). For intrinsically safe installations, refer to Bently Nevada installation drawings 141092 and 140979 to verify loop wiring and entity parameters: Ui = -28 V, Ii = 140 mA, Pi = 0.91 W, Ci = 1.5 nF, and Li = 610 uH.
