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

Description

Designed for critical industrial turbomachinery protection, the Bently Nevada 330101-00-10-10-12-05 is a high-performance proximity probe that delivers precise, non-contact shaft vibration and displacement measurements. This specific configuration of the 3300 XL 8 mm Proximity Transducer System is optimized for installations with tight spacing constraints, featuring a 0.0-inch unthreaded length and a 1.0-inch fully threaded overall case length with a standard 3/8-24 UNF threaded body. This compact design allows for direct, flush mounting on bearing housings and machinery casings.

A key technical highlight of this configuration is the integration of a 1.0-meter (3.3-foot) lead cable engineered with patented FluidLoc cable technology (Option 12). The FluidLoc design blocks lubricating oil and other process fluids from leaking out of the machine housing through the interior of the probe cable, maintaining environmental containment. The cable is terminated with a gold-plated miniature coaxial ClickLoc connector, which provides a secure mechanical connection with simple finger-tight torque. Additionally, this assembly is certified under Option 05, providing comprehensive CSA, ATEX, and IECEx approvals for use in hazardous areas.

Features

• Eddy-current sensor tip with an 8 mm diameter optimized for high-accuracy non-contact displacement and vibration measurements.
• FluidLoc cable construction (Option 12) blocks oil and other process liquids from weeping or migrating through the interior of the cable.
• Patented TipLoc molding method provides an exceptionally strong bond between the probe tip polymer and the stainless steel threaded casing.
• Rugged CableLoc cable attachment design delivers up to 330 N (75 lbf) of pull strength to protect the cable-to-probe connection.
• Corrosion-resistant, gold-plated ClickLoc coaxial connector locks firmly in place with an audible "click" and requires no specialized tools.
• Standard 3/8-24 UNF-2A threaded stainless steel body, supplied without external armor.
• Certified under Option 05 for robust safety compliance in CSA, ATEX, and IECEx hazardous environments.
• Fully compatible with standard 3300 XL Proximitor sensors (330180 series) and standard extension cables.

Applications

• Steam and gas turbine radial shaft vibration and rotor dynamic analysis.
• Thrust and axial shaft displacement monitoring in high-speed compressors, pumps, and fans.
• Runout and shaft motion monitoring on hydroelectric generator shafts.
• High-pressure bearing housings and oil-sealed machinery casings where fluid migration along sensor cables must be completely contained.
• Machinery protection and condition monitoring chains within power generation, petrochemical, and oil and gas processing plants.

Installation Guidelines

Mount the probe with the appropriate probe gap per system calibration, typically 1.27 mm (50 mils) for a standard AISI 4140 steel target. Ensure the thread mounting holes are free from burrs and contaminants before installation. When routing cables, follow proper industrial shielding and grounding practices to prevent electromagnetic or radio frequency interference. Secure the ClickLoc connectors with finger-tight torque until they lock with an audible click, and ensure the minimum cable bend radius is maintained to protect the coaxial core.

Compliance and Certifications

This proximity probe is qualified for use in hazardous areas with Option 05, certifying it under CSA, ATEX, and IECEx. For intrinsically safe installations, refer to the official Bently Nevada installation drawings 141092 and 140979 to verify entity parameters (including Ui = -28 V, Ii = 140 mA, Pi = 0.91 W, Ci = 1.5 nF, and Li = 610 uH) and wiring instructions for intrinsically safe or non-incendive configurations.
