330104-05-10-10-02-05 3300 XL 8 mm Proximity Probe | Bently Nevada

Product Overview

The Bently Nevada 330104-05-10-10-02-05 operates as a high-precision, non-contacting eddy current sensor within the industry-standard 3300 XL 8 mm Proximity Transducer System. This specialized probe tracks dynamic shaft radial vibration, axial displacement (thrust position), and fluid-film bearing clearances in critical rotating assets. It transmits continuous voltage data directly to machinery protection monitors to safeguard high-speed steam turbines, centrifugal compressors, and large process pumps from catastrophic failure. We supply this premium industrial component in 100% brand new, original factory-sealed condition to guarantee original calibration curves, stable signal output, and immediate deployment for plant safety management.

Part Number Breakdown

Bently Nevada builds this 3300 XL probe configuration utilizing a modular engineering matrix. The model string 330104-05-10-10-02-05 represents the following specific physical and regulatory options:

Technical Specifications

This metric-threaded proximity probe integrates robust cable shielding and global certifications to withstand aggressive field routing and explosive atmospheres.

• Thread Profile: M10 x 1 metric thread

• Cable Protection: Integrated flexible stainless steel armor sleeve

• Unthreaded Case Length: 50 mm

• Overall Case Length: 100 mm (leaves 50 mm of functional threaded casing)

• Total Integrated Cable Length: 1.0 meter (3.3 feet)

• Interconnect Termination: Gold-plated miniature coaxial ClickLoc™ connector

• Regulatory Compliance: ATEX / IECEx / North American hazardous area certifications (Intrinsically Safe)

• Probe Tip Material: Polyphenylene sulfide (PPS)

• Probe Case Material: AISI 303 or 304 Stainless Steel (SST)

• Country of Origin: United States of America (USA)

Engineering Advantages

• Explosion-Proof Certification: The -05 option provides global hazardous area certifications (including ATEX and IECEx). This allows instrumentation engineers to safely deploy the sensor inside classified chemical processing zones, oil refineries, and gas handling facilities.

• Armored Defense Against Severing: The integrated stainless steel mechanical armor prevents crushing, abrasion, and pinching when field technicians route the probe cable past sharp machine corners or through tightly packed conduit runs.

• Adjustable Depth Clearance: The 50 mm unthreaded section combined with a 100 mm overall case enables optimized positioning inside targeted bracket counterbores. This prevents internal case binding while ensuring the sensing tip clears surrounding internal metal structures to eliminate side-view interference.

• Positive-Lock Signal Continuity: The gold-plated ClickLoc™ coaxial connector eliminates signal attenuation and high-impedance drift. The connector mechanism resists high-frequency machinery frame vibration, preventing accidental disconnections that trigger false plant trips.

FAQs

• What specific extension cable must I pair with this 1.0-meter armored probe?

  A standard 3300 XL Proximitor sensor calibrates for a total system length of either 5.0 meters or 9.0 meters. Because this probe integrates a 1.0-meter cable, you must insert either a 4.0-meter or an 8.0-meter armored 3300 XL extension cable to complete the tuned RF circuit and maintain exact factory scaling.

• What is the critical mechanical torque limit for this M10 x 1 probe housing?

  Tighten the probe case to a maximum torque of 4.5 N·m (40 in·lb) using a calibrated torque tool. Exceeding this torque threshold stretches the stainless steel casing, tears the delicate internal coil winding wires, and permanently ruins the eddy current transducer.

• Does the -05 hazardous area option require specific barrier grounding during installation?

  Yes. To maintain the intrinsic safety rating designated by the -05 approval option, you must wire the system through approved intrinsic safety barriers or galvanic isolators within the control panel. This setup limits the electrical energy entering the hazardous process zone to prevent ignition.
