330104-00-20-10-01-CN | Bently Nevada | 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330104-00-20-10-01-CN acts 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 vibration, axial displacement (thrust), and fluid-film bearing clearances in critical rotating machinery. It feeds real-time voltage signals directly to machinery protection systems to safeguard high-speed steam turbines, centrifugal compressors, and large industrial pumps from catastrophic damage. We supply this premium technical component in 100% brand new, original factory-sealed condition to guarantee original calibration curves and full compliance with hazardous area regulations.

Part Number Breakdown

Bently Nevada configures this specific 3300 XL probe option sequence to meet distinct mechanical reach and regional regulatory mandates. The model number 330104-00-20-10-01-CN breaks down into the following engineered parameters:

Technical Specifications

Engineering Advantages

• Regional Hazardous Area Compliance: The -CN suffix indicates official NEPSI certification. This allows instrumentation engineers to safely install this sensor in classified explosive atmospheres within petrochemical plants, gas handling facilities, and refineries operating inside mainland China.

• Extended Deep-Housing Reach: The 200 mm overall case length targets deep internal bearing blocks or passes effortlessly through thick outer machine insulation jackets. The 0 mm unthreaded specification ensures full-length thread contact, maximizing mounting clamping force and completely eliminating probe housing vibration caused by high-velocity oil mist windage.

• Aggressive Fluid Protection: High-grade polyphenylene sulfide (PPS) completely seals the probe tip. The material resists degradation from high-pressure moisture, steam ingress, and harsh synthetic turbine oils or aggressive hydrocarbon lubricants.

• Positive-Locking Signal Shielding: The gold-plated ClickLoc™ coaxial connector maintains low electrical resistance over time. It prevents signal degradation from micro-fretting corrosion caused by persistent high-frequency asset chassis vibration.

FAQs

• What specific extension cable must I pair with this 1.0-meter 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 3300 XL extension cable to complete the tuned RF circuit and maintain exact factory scaling.

• What mounting torque prevents casing damage during installation?

  Always tighten this M10 x 1 stainless steel case to a maximum torque limit of 4.5 N·m (40 in·lb). Forcing the long 200 mm body beyond this limit stretches the outer steel casing and snaps the delicate micro-wires running to the internal face coil, instantly destroying the 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 intrinsic safety loop certification within areas requiring NEPSI compliance, your extension cable and Proximitor sensor should carry matching regional certification marks.
