Bently Nevada 330904-00-15-05-11-05: Hazardous Area & Fluid-Resistant Transducer

Complete Model Suffix Analysis

• Every segment of the code 330904-00-15-05-11-05 defines a critical feature for harsh-duty use.
• Base Model (330904): 3300 NSv Probe with M8X1 thread and stainless steel conduit armor.
• Unthreaded Length (-00): 0 mm. Standard probe tip placement.
• Case Length (-15): 150 mm extended case for secure mounting in thick structures.
• Total Length (-05): 0.5 meter (20 in) total system length.
• Cable & Connector (-11): The key differentiator: Miniature coaxial ClickLoc connector with protector on a specialized FluidLoc cable for superior fluid resistance.
• Agency Approval (-05): Includes major certifications: CSA, ATEX, and IECEx for use in hazardous locations.

Core Technical Specifications

• Brand: Bently Nevada
• Model: 330904-00-15-05-11-05
• Linear Range: 1.5 mm (60 mils), operating from 0.25 to 1.75 mm gap.
• Scale Factor & Accuracy: 7.87 V/mm (200 mV/mil) ±20% tolerance. Linearity better than ±0.06 mm (±2.3 mils).
• Frequency Response: 0 to 10 kHz (-3 dB typical with 305m field wiring).
• Target Size: Minimum 8.9 mm (0.35 in) diameter; 13 mm (0.5 in) recommended.
• Environmental Robustness: Operating/Storage Temp: -52°C to +177°C (-62°F to +351°F). Sealed with a Viton O-ring.

Key Features for Harsh Environments

• FluidLoc Cable System (-11): This is not standard cable. The FluidLoc design provides enhanced sealing and chemical resistance at the critical probe-to-cable junction, offering superior protection against oils, coolants, and process fluids.
• Hazardous Area Certified (-05): The CSA, ATEX, and IECEx approvals mean this system is designed and tested for safe operation in areas with potentially explosive atmospheres (e.g., Zone 1/21, Zone 2/22), a critical requirement for refineries and chemical plants.
• Extended Armored Case (-15): The 150mm armored case provides maximum physical protection for the probe and cable entry in high-vibration or high-risk mechanical impact areas.
• Ruggedized Materials: Features a chemical-resistant PPS probe tip, AISI 304 stainless steel case, and FEP-insulated cable for long-term durability.

Installation & Compliance Notes

• Gap Setting: Always set to the recommended 1.0 mm (40 mils) gap for certified performance.
• Certification Compliance: To maintain the hazardous area ratings, the entire system (probe, cable, and 3300 XL NSv Proximitor Sensor) must be installed per the relevant certification standards (e.g., ATEX) and local codes.
• Connector Use: The -11 suffix includes a connector protector. Always use it to maintain the environmental seal of the ClickLoc connection.
• Bend Radius: Adhere to the 25.4 mm (1.0 in) minimum bend radius to prevent cable damage.

Frequently Asked Questions (FAQ)

• Q: What exactly is FluidLoc cable, and why is it important?
  A: FluidLoc is a Bently Nevada design that significantly improves the seal at the cable-to-probe connection. It offers much better resistance to fluid ingress and chemical attack compared to the standard cable, drastically reducing failure rates in wet environments.
• Q: Can I use this probe in a Zone 1 hazardous area?
  A: Yes, when used with an appropriately certified 3300 XL NSv Proximitor Sensor and installed according to the control drawings for the ATEX/IECEx certification, this system is suitable for Zone 1/21 and Zone 2/22 hazardous areas.
• Q: Is the FluidLoc feature (-11) available with other case lengths?
  A: Yes. The -11 cable/connector suffix can typically be ordered with other standard case lengths (e.g., -10 for 100mm) to meet your mechanical installation needs while providing fluid resistance.
• Q: What is the main difference between this "-11-05" model and a standard "-02-00" model?
  A: The differences are major: This model has (1) FluidLoc cable for fluid resistance, (2) a connector protector, and (3) hazardous area certifications. The standard model has none of these, making it suitable only for general-purpose, non-hazardous areas.
• Q: Do you supply the matching certified Proximitor Sensor?
  A: Yes. To form a complete, certified monitoring loop, you will need a 3300 XL NSv Proximitor Sensor with corresponding hazardous area approvals. We can provide the correctly specified sensor and system documentation.
