330141-08-90-11-05 Bently Nevada 3300 XL 8mm Armored Proximity Probe

Product Introduction

The Bently Nevada 330141-08-90-11-05 is a premium 3300 XL 8mm proximity probe featuring integrated stainless steel armor and FluidLoc technology. Engineered for the most demanding industrial environments, this sensor utilizes patented TipLoc and CableLoc construction to ensure maximum mechanical integrity under high tensile loads. The 8mm diameter provides superior robustness against physical impact compared to smaller alternatives.

Global PLC Spare HUB's Insight

The 330141-08-90-11-05 is our "Industrial Workhorse" for oily and physically demanding environments. The key differentiator here is the FluidLoc option combined with Armor. In many turbine applications, lubricating oil can travel inside the probe cable (wicking) and leak into the Proximitor housing; FluidLoc prevents this entirely. The 9-meter total length is a strategic choice for large machines, as it allows for a direct run to the junction box without intermediate connectors, maximizing signal reliability and simplifying the installation footprint.

Typical Application & Diagnostic Capability

• Target Machinery: Large steam turbines, centrifugal compressors, and heavy-duty water pumps.
• Diagnostic Power: High-resolution radial vibration monitoring and axial thrust position detection.
• Environmental Suitability: Optimized for high-humidity (IEC 68-2-3) and hazardous locations requiring Ex-certification.

Commercial & Logistics

• Condition: New & Original in Factory Packing (Made in U.S.A.)
• Warranty: 12 Months Comprehensive Warranty
• Dispatch Time: Fast fulfillment within 24 to 48 hours
• Express Delivery: Global shipping via FedEx, UPS, or DHL

Technical FAQ (Field Experience)

• Q: Why choose a 9-meter probe over the standard 1-meter or 5-meter versions?
• A: The 330141-08-90-11-05 allows for a "direct-connect" system in larger machinery. This eliminates the signal loss and potential failure points associated with intermediate extension cable connectors.
• Q: How does the FluidLoc technology assist in long-term maintenance?
• A: It acts as an internal cable seal. Without FluidLoc, oil can seep through the cable interior and damage the Proximitor sensor or contaminate the control panel, leading to significant repair costs.
• Q: Is this 9.0-meter probe compatible with standard 3300 XL extension cables?
• A: No. This 9-meter probe must connect directly to a 9-meter Proximitor. Adding an extension cable will change the electrical length, causing a severe Scale Factor (ISF) error in vibration readings.
• Q: What is the benefit of the ClickLoc connector protector included in this model?
• A: The protector (Option 11) prevents the miniature coaxial connection from loosening due to machine vibration and seals the connection against moisture and dust ingress.
• Q: Can I use this armored probe on a target other than AISI 4140 steel?
• A: Yes, but the 200 mV/mil sensitivity is factory-calibrated for 4140 steel. Using other materials will change the output slope, necessitating a correction factor in your monitoring software.
