Bently Nevada 330104-00-06-05-01-05 3300 XL 8 mm Proximity Probe

Product Overview

In the evolution of industrial rotating machinery monitoring, the need for precise, non-contact measurement has become paramount. The Bently Nevada 330104-00-06-05-01-05 3300 XL 8 mm Proximity Probe addresses this demand with proven reliability. As part of the 3300 XL series, this probe delivers accurate shaft vibration and position data essential for protecting critical assets like steam turbines, compressors, and pumps. Engineered for harsh environments, it features a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, ensuring long-term durability.

Technical Specifications Breakdown

The 330104-00-06-05-01-05 is configured with a 0.5 meter (1.6 feet) total length and a 60 mm overall case length. It uses an M10 x 1 thread with armor for robust mounting. The connector and cable option is a miniature coaxial ClickLoc connector with connector protector and standard cable, providing secure signal transmission. Agency approvals include CSA, ATEX, and IECEx, confirming its suitability for hazardous area installations. The probe tip material is polyphenylene sulfide (PPS), and the case material is AISI 303 or 304 stainless steel. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Electrical specifications show a nominal probe DC resistance of 7.45 ± 0.50 Ω for the 0.5 meter length. The system requires a -17.5 Vdc to -26 Vdc power supply and delivers an output resistance of 50 Ω.

Industry Applications

This proximity probe is widely deployed in oil and gas, power generation, and petrochemical facilities for radial vibration and axial position monitoring. In a typical steam turbine application, the 330104-00-06-05-01-05 provides real-time data to the protection system, enabling early detection of shaft misalignment or bearing wear. Its ATEX and IECEx approvals allow installation in explosive atmospheres, such as those found in gas compressor trains. The probe's robust stainless steel construction and sealed design resist contamination from process fluids and debris, reducing unplanned downtime.

Installation & Setup Guidance

Proper mounting is critical for accurate measurements. The M10 x 1 threaded design requires a compatible mounting bracket or adapter. Ensure the probe tip is clean and free from debris before installation. Gap the probe at 1.27 mm (50 mils) to the target surface for optimal performance. Use the miniature coaxial ClickLoc connector for a secure, quick connection to the extension cable. Verify that the system power supply meets the -17.5 Vdc to -26 Vdc requirement. For hazardous area installations, follow the installation drawing 140979 for non-incendive circuit connections.

Maintenance & Reliability

Routine inspection of the probe tip and cable is recommended to ensure reliable operation. Check the Viton O-ring seal integrity if the probe is exposed to aggressive chemicals or high differential pressure. The stainless steel case and PPS tip resist corrosion and wear, extending service life. Periodic verification of the system calibration against an AISI 4140 steel target helps maintain measurement accuracy. For long-term reliability, store spare probes in a clean, dry environment.

Compatibility & Integration

The 330104-00-06-05-01-05 is designed to work with 3300 XL 8 mm Proximitor Sensors and extension cables. It accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm probe and extension cable. The system provides a 50 Ω output resistance, compatible with most monitoring systems. For replacement or upgrade projects, verify that the existing cabling and connectors match the miniature coaxial ClickLoc option. plcmatrix.com offers this probe along with compatible sensors and accessories to simplify procurement.
