Bently Nevada 330104-10-16-10-12-05 3300 XL 8 mm Proximity Probe

Product Overview

When unplanned downtime threatens rotating machinery, the Bently Nevada 330104-10-16-10-12-05 3300 XL 8 mm Proximity Probe delivers precise shaft vibration and position measurements. This probe forms part of the trusted 3300 XL series, engineered for reliability in harsh industrial environments. With its M10 x 1 thread and armored construction, it withstands demanding conditions while maintaining accuracy.

Technical Specifications

The 330104-10-16-10-12-05 offers a 100 mm unthreaded length and 160 mm overall case length. Total length reaches 1.0 meter (3.3 feet). A miniature coaxial ClickLoc connector with FluidLoc cable ensures secure signal transmission. The probe tip uses polyphenylene sulfide (PPS) material, while the case is AISI 303 or 304 stainless steel. Nominal probe DC resistance measures 7.59 ± 0.50 Ω at 1.0 meter length. The probe seals differential pressure between tip and case using a Viton O-ring.

Industry Applications

This probe excels in turbomachinery, compressors, pumps, and fans where early fault detection prevents catastrophic failures. In oil and gas facilities, the CSA, ATEX, and IECEx approvals allow installation in hazardous areas. Compared to standard proximity probes, the 3300 XL series offers improved linearity and temperature stability, reducing false alarms and maintenance costs.

Installation & Setup Guidance

Mount the probe with proper gap setting per manufacturer guidelines. Use the M10 x 1 thread for secure installation. Ensure the target surface is clean and made of AISI 4140 steel for optimal performance. Connect the miniature coaxial ClickLoc connector to the extension cable, then route the FluidLoc cable away from high-interference sources. Verify power supply between -17.5 Vdc and -26 Vdc for non-incendive circuits.

Maintenance & Reliability

Regularly inspect the probe tip and cable for damage or contamination. The PPS tip resists many chemicals, but avoid abrasive cleaning. Check O-ring integrity during maintenance intervals to maintain pressure sealing. The stainless steel case provides corrosion resistance in humid or corrosive atmospheres. Following these steps extends service life and reduces total cost of ownership.

Compatibility & Integration

The 330104-10-16-10-12-05 works with 3300 XL Proximitor Sensors and extension cables. It accepts 3300-series 5 mm and 8 mm probes. The system requires a -24 Vdc power supply and 10 kΩ load for standard calibration. For hazardous locations, use intrinsically safe zener barriers per drawing 141092 or galvanic isolators. Non-incendive installations follow drawing 140979.

Selection Guide & Purchasing Advice

Before ordering, verify your required cable length, thread size, and agency approvals. The 330104-10-16-10-12-05 includes CSA, ATEX, and IECEx certifications. For replacement or new installations, confirm compatibility with your existing Proximitor and extension cable. plcmatrix.com stocks this probe and can advise on lifecycle status and alternatives.
