Bently Nevada 330104-10-16-05-01-00 3300 XL 8 mm Proximity Probe

Product Overview

When machinery vibration threatens uptime and safety, the Bently Nevada 330104-10-16-05-01-00 delivers precise, reliable measurements. This 3300 XL 8 mm proximity probe, metric, is designed for continuous monitoring of shaft vibration and position in critical rotating equipment. Part of the trusted 3300 XL series, it offers a robust solution for industrial applications requiring high accuracy and durability.

Technical Specifications

The 330104-10-16-05-01-00 features a 2 mm (80 mils) linear range, starting at approximately 0.25 mm (10 mils) from the target and extending to 2.3 mm (90 mils), corresponding to approximately -1 to -17 Vdc. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel (SST). It operates over a standard temperature range of -52°C to +177°C (-62°F to +350°F). The nominal probe DC resistance (RPROBE) is 7.45 ± 0.50 ohms for the 0.5 meter length.

Industry Applications

This probe excels in monitoring steam turbines, compressors, pumps, and other rotating machinery where precise shaft displacement measurement is critical. Its 2 mm linear range and -9 Vdc recommended gap make it ideal for radial vibration monitoring in high-speed equipment. The stainless steel case and PPS tip ensure reliable performance in harsh environments, including those with high humidity (less than 3% change in ASF after 56 days at 93% humidity per IEC 68-2-3).

Installation & Setup Guidance

For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned wiring. The maximum cable length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). The probe case thread is M10x1, with a maximum thread engagement of 15 mm. Ensure the probe is not exposed to temperatures below -34°C (-30°F) to avoid premature pressure seal failure. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Maintenance & Reliability

Regular inspection of the probe and cable for physical damage is recommended. The probe's stainless steel construction and PPS tip resist corrosion and wear, extending service life. For applications requiring intrinsic safety, the probe can be installed with zener barriers per drawing 141092 or galvanic isolators for Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga; Class 1, Groups A, B, C, D; Class II, Groups E, F, G; Class III. For non-incendive installations, use drawing 140979 for Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc; Class 1, Division 2, Groups A, B, C, D.

Selection Guide & Purchasing Advice

Before ordering, verify the probe length (0.5 meter), connector type (miniature coaxial ClickLoc with connector protector and standard cable), and agency approval (not required). The 330104-10-16-05-01-00 is a metric version with M10x1 thread and 100 mm unthreaded length.
