Description

Designed for demanding industrial machinery monitoring environments where mechanical clearances are highly restricted, the 330901-00-15-05-02-CN proximity probe belongs to the reliable Bently Nevada 3300 NSv transducer family. This high-precision eddy current sensor is engineered to measure static and dynamic shaft movement, making it highly effective for radial vibration, axial position, and speed measurements on small-diameter shafts or targets with tight mounting space constraints.

The sensor features a specialized miniature coaxial ClickLoc connector and standard cable configuration, ensuring robust signal integrity and easy installation in tight instrument enclosures. With an unthreaded length of 0.0 inches and an overall case length of 1.5 inches, this configuration is optimized for direct-thread mounting where flush housing alignments are required. The probe delivers high sensitivity and precise displacement data directly to compatible 3300 NSv Proximitor Sensors, assisting maintenance teams in preventing catastrophic rotating machinery failures.

Features

• Optimized for machinery with tight physical installation limits and small target areas.
• Equipped with a secure ClickLoc miniature coaxial connector to minimize signal attenuation and simplify field connection.
• Robust construction designed to withstand exposure to harsh industrial fluids, oils, and physical vibrations.
• Country-specific agency approvals (CN option) for verified hazardous area compliance.
• Highly reliable eddy current measurement principle with low susceptibility to electrical noise.

Applications

• Centrifugal and axial air compressors
• Small-scale steam turbines and high-speed gas turbines
• Boiler feed pumps and industrial gearboxes
• Petrochemical processing plants and oil & gas refining facilities
• Power generation and water treatment facilities

Installation Guidelines

• Calibration Check: Verify calibration of the probe with the corresponding 3300 NSv Proximitor Sensor prior to final installation.
• Clearance Requirements: Maintain sufficient side clearance around the probe tip to prevent cross-talk or side-loading interference from surrounding structural metal.
• Cable Protection: Route the extension cable through dedicated conduit or cable trays to protect against mechanical wear and chemical exposure. Do not bend the cable past its minimum rated bend radius.
• Connector Protection: Ensure the ClickLoc connectors are clean, dry, and free of grease during mating. Use self-coalescing silicone tape to seal the connection from environmental moisture.
