Description

Engineered for high-reliability non-contact shaft displacement and vibration measurements, the Bently Nevada 330103-00-03-90-02-00 is an essential transducer element for machinery protection systems. This eddy-current-based proximity probe features an 8 mm tip diameter, providing continuous monitoring of critical mechanical parameters such as radial vibration, axial position, and speed in high-speed rotating machinery.

As part of the rugged 3300 XL series, this model is configured with a 30 mm overall threaded case length, featuring 0 mm of unthreaded length (fully threaded casing). The integrated standard coaxial cable extends to a total length of 9.0 meters (29.5 feet) and is terminated with a miniature coaxial ClickLoc connector, ensuring robust signal integrity and resistance to extreme machinery environments.

Features

• Engineered Durability: The probe tip is molded from high-performance Polyphenylene sulfide (PPS) to withstand harsh process temperatures and chemicals.
• Corrosion Resistant Casing: Constructed with AISI 303 or 304 stainless steel (SST) thread housing.
• Viton O-Ring Sealing: Incorporates a reliable Viton O-ring seal to prevent differential pressure leakage between the probe tip and case.
• ClickLoc Coaxial Connection: Equipped with a miniature coaxial ClickLoc connector for quick, secure, and vibration-proof coupling to extension cables.
• Direct System Compatibility: Fully compatible with Bently Nevada 3300 XL series Proximitor sensors and standard monitoring rack systems.

Applications

• Steam, gas, and hydro turbines
• Centrifugal, axial, and reciprocating compressors
• High-capacity process pumps and electric motors
• Industrial gearboxes and power transmission systems
• Machinery diagnostics and predictive maintenance platforms

Installation Guidelines

• Thread Protection: Hand-tighten the probe case into the mounting port before applying final torque to avoid cross-threading the stainless steel casing.
• Cable Bend Radius: Ensure a minimum static bend radius of 25.4 mm (1.0 inch) is maintained when routing the coaxial cable to prevent internal conductor damage.
• Connector Protection: Verify that the miniature coaxial ClickLoc connector is clean and dry prior to connection. Use connector silicone sleeve kits or conduit housing if the connection is exposed to moisture or oil.
• Calibration Gap: Use a mechanical micrometer or proximity probe calibrator to set the nominal gap (typically 1.27 mm or 50 mils) corresponding to the system's electrical center point.
