Bently Nevada 330104-10-20-10-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330104-10-20-10-02-00 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 sensor in 100% brand new, original factory-sealed condition, guaranteeing intact factory calibration curves and certified compliance for regional hazardous zone deployment.

Part Number Breakdown

Engineering Advantages

• Regional Hazardous Zone Compliance: The -CN suffix indicates official certification for regional hazardous area mandates. This enables instrumentation engineers to safely deploy the sensor inside classified explosive atmospheres within processing plants, gas fields, and refineries requiring specific localized approvals.

• Armored Defense Against Physical Severing: The integrated flexible stainless steel armor sleeve, shielded by an FEP outer jacket, prevents crushing, abrasion, and pinching. This setup protects the internal core line when field technicians route the probe cable past sharp machine corners or through tightly packed conduit runs.

• Patented TipLoc and CableLoc Robustness: The design utilizes the patented TipLoc molding method to forge an unbreakable bond between the PPS probe tip and the stainless steel body. Combined with the CableLoc design, the assembly provides a massive pull strength of 330 N (75 lbf), preventing the cable from pulling out of the sensor head during aggressive installation maneuvers.

• Clearance via Unthreaded Section: The 100 mm unthreaded sleeve combined with a 200 mm total 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 electrical interference.

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.

• Can I use this probe with a standard non-CN marked 3300 XL Proximitor sensor?

  Yes. Electrically, the probe matches all standard 3300 XL system components. However, to maintain full loop certification within areas strictly enforcing the regional compliance designated by the -CN code, your extension cable and Proximitor sensor should carry matching regional certification marks.
