Bently Nevada 330104-14-19-10-11-05 3300 XL 8 mm Proximity Probe

Product Overview

As industrial machinery evolves toward higher speeds and tighter tolerances, the need for precise vibration monitoring has never been greater. The Bently Nevada 330104-14-19-10-11-05 3300 XL 8 mm Proximity Probe addresses this demand with proven reliability. This probe is part of the 3300 XL series, designed for non-contact displacement measurements in rotating equipment like turbines, compressors, and pumps. With its armored construction and agency approvals, it suits demanding applications where accuracy and durability are paramount.

Technical Specifications

The 330104-14-19-10-11-05 features an M10 x 1 thread and an unthreaded length of 140 mm. The overall case length is 190 mm, and the total probe length is 1.0 meter (3.3 feet). It uses a miniature coaxial ClickLoc connector with FluidLoc cable and includes a connector protector. The probe tip is made of polyphenylene sulfide (PPS), while the case is AISI 303 or 304 stainless steel. Nominal DC resistance from center to outer conductor is 7.59 ± 0.50 ohms. Agency approvals include CSA, ATEX, and IECEx, ensuring compliance with international safety standards.

Industry Applications

This proximity probe excels in monitoring shaft vibration and position in critical rotating machinery. In the oil and gas sector, it helps detect early signs of bearing wear or imbalance in compressors. In power generation, it provides real-time data for turbine protection systems. The probe's PPS tip and stainless steel case resist harsh chemicals and high temperatures, making it suitable for refinery and chemical plant environments.

Installation & Setup Guidance

Proper installation is key to accurate measurements. Mount the probe using the M10 x 1 thread into a drilled and tapped hole, ensuring the tip is perpendicular to the target surface. Gap the probe at 1.27 mm (50 mils) for optimal linear range. Use the miniature coaxial ClickLoc connector for secure cable attachment. Verify that the extension cable and Proximitor sensor are 3300 XL 8 mm compatible to maintain system accuracy. Always follow the installation drawing 140979 for non-incendive circuit connections.

Maintenance & Reliability

Regular inspection of the probe tip and cable for physical damage is recommended. The Viton O-ring seals differential pressure between tip and case, so check for leakage during routine maintenance. Clean the probe tip with a soft cloth if debris accumulates, but avoid solvents that may damage the PPS material. The 330104-14-19-10-11-05 is designed for long service life, reducing downtime and replacement costs.

Compatible Systems & Integration

This probe works exclusively with 3300 XL 8 mm Proximitor sensors and extension cables. It accepts a -17.5 Vdc to -26 Vdc power supply and delivers a linear output with less than 2 mV change per volt change in input voltage. The output resistance is 50 ohms. For best performance, use an AISI 4140 steel target and calibrate the system as a matched set. Ensure your monitoring system supports the 3300 XL series for seamless integration.

Buying Guide & Purchasing Advice

Before ordering, confirm that the 330104-14-19-10-11-05 matches your required thread size, cable length, and agency approvals. Verify compatibility with your existing Proximitor and extension cable.
