Bently Nevada 330104-00-08-10-02-CN 3300 XL 8 mm Proximity Probe

Description

Engineered for high-performance machinery protection, the 330104-00-08-10-02-CN proximity probe is a critical sensing element within the Bently Nevada 3300 XL series. This 8 mm eddy current transducer system delivers precise, continuous measurements of static and dynamic shaft alignment, thermal expansion, radial vibration, and axial position in demanding rotary machinery environments. By transforming physical proximity variations into high-frequency electrical signals, it enables real-time diagnostics of critical assets.

This specific configuration is designed without unthreaded length, utilizing an 80 mm fully threaded case and a 1.0-meter integrated coaxial cable. Equipped with a reliable ClickLoc connector, the probe maintains consistent electrical contact while resisting physical disconnection caused by vibration. The robust Viton O-ring construction provides high-integrity sealing, shielding the internal probe electronics from process fluids and differential pressure changes.

Features

• Resilient Probe Tip: Manufactured with polyphenylene sulfide (PPS) for chemical inertness and mechanical stability across extreme thermal shifts.
• Durable Case Construction: High-grade AISI 303 or 304 stainless steel housing prevents chemical deterioration and physical wear.
• Secure Coaxial Interface: Miniature ClickLoc connector ensures a stable, low-noise connection with standard extension cables.
• Viton O-Ring Seal: Designed to seal pressure differences between the probe tip and case to prevent oil or moisture ingress.
• Broad Compatibility: Seamlessly integrates with Bently Nevada 3300 XL Series Proximitor Sensors and standard mounting hardware.

Applications

• Heavy industrial steam turbines and gas turbines
• Centrifugal, axial, and reciprocating compressors
• High-pressure water pumps and cooling fans
• Hydroelectric generator bearings
• General turbomachinery vibration monitoring (TSI systems)

Technical Specifications

Installation Guidelines

• Cable Handling: Avoid sharp bends when routing the coaxial cable. Observe the minimum physical bend radius to preserve internal shielding integrity.
• Torque Limits: Follow nominal torque specifications when installing the threaded case into the machinery housing to prevent damage to the stainless steel threads and PPS tip.
• Connector Cleanliness: Ensure the miniature ClickLoc connector surfaces remain dry and free of oil, dust, or contaminants prior to connection.
• Electrical Isolation: Insulate connection terminals and use protective conduit where mechanical wear or electromagnetic interference (EMI) is present.
