Bently Nevada 330101-00-22-05-02-CN 3300 XL 8 mm Proximity Probe

Description

Engineered for highly accurate non-contact dynamic displacement and vibration measurements, the Bently Nevada 330101-00-22-05-02-CN acts as a key transducer component within critical machinery protection systems. This 3300 XL 8 mm series proximity probe is built to operate under demanding conditions, converting physical shaft movement into clean electrical signals when paired with a compatible Proximitor Sensor. It features an unthreaded body design with a 2.2-inch overall case length and is terminated with a 0.5-meter cable and a robust ClickLoc miniature coaxial connector. This configuration is ideal for fluid-film bearing monitoring in high-vibration turbomachinery environments requiring certified compliance under localized agency standards.

Features

• ClickLoc Coaxial Connection: Uses a miniature coaxial ClickLoc connector to prevent accidental disconnection during thermal cycling and high-frequency vibrations.
• Rugged Case Construction: Features a robust stainless steel case with specialized internal potting to resist moisture, oil, and harsh chemical exposure.
• Precision Thermal Stability: Maintains minimal output drift across standard operating temperatures, ensuring reliable gap measurements.
• Interchangeable Design: Fully compatible with standard 3300 XL 8 mm extension cables and proximitor systems.
• CN Approval Certified: Compliance-rated for specific regional hazardous areas and strict environmental protection standards.

Applications

• Steam and gas turbine shaft dynamic vibration and position tracking.
• Hydroelectric generator shaft centerline and rotor position monitoring.
• Centrifugal compressor radial dynamic displacement analysis.
• Heavy industrial gearbox shaft thrust dynamic positioning.
• High-speed pump and blower fluid-film bearing clearance verification.

Connections and Interfaces

Alternative Models & Compatibility

The total physical length of your transducer system must always match the calibration system of the Proximitor Sensor. Because this model features a 0.5-meter probe length, it is strictly designed to pair with either a 4.5-meter extension cable (forming a complete 5.0-meter system) or an 8.5-meter extension cable (forming a complete 9.0-meter system). Mixing incompatible probe/cable lengths shifts the system's electrical resonance, leading to severe linear scale-factor errors (deviating from the nominal 7.87 V/mm scale factor).

Application Pitfalls & Engineering Notes

Care must be exercised when handling proximity probe cables to prevent kinking. The minimum bend radius of the coaxial cable is 25.4 mm (1.0 inch). Exceeding this limit can crush the dielectric core, altering the cable impedance and introducing measurement errors. Ensure that the total run length of extension cabling is properly secured within protective conduits to avoid physical wear and electrical noise pick-up in high EMI/RFI machinery spaces.

Commissioning & Wiring Tips

When making connections with the ClickLoc coaxial system, ensure the physical terminations are completely dry and free from contaminants like oil or coolant. Once mated, wrap the connector interface with a specialized silicone connector protector sleeve. This sleeve acts as a moisture barrier and isolates the outer metallic shield from machine ground, preventing ground loop interference that degrades dynamic vibration readings.
