Bently Nevada 330104-00-14-10-02-00 3300 XL 8 mm Proximity Probe

Description

Executing reliable non-contact dynamic displacement and static distance measurements, the Bently Nevada 330104-00-14-10-02-00 is an industrial-grade sensor optimized for critical rotating machinery. As part of the 3300 XL 8 mm Proximity Transducer System, this unthreaded smooth-case probe is engineered to operate in harsh processing environments, providing highly linear feedback of shaft vibration, axial position, and speed. The physical configuration comprises a 140 mm overall case length, a 1.0-meter integrated coaxial cable terminated with a miniature coaxial ClickLoc connector, and a durable polyphenylene sulfide (PPS) tip design to withstand chemical and thermal exposure.

Features

• Unthreaded Smooth Case: Features a 0 mm unthreaded length option, designed specifically for insertion-style mounting brackets or specialized industrial housing assemblies.
• Robust Tip Construction: Molded from polyphenylene sulfide (PPS), offering high resistance to corrosive chemicals, steam, and mechanical wear.
• ClickLoc Coaxial Connection: Equipped with a gold-plated miniature coaxial ClickLoc connector providing secure, vibration-resistant cable mating without requiring specialty tooling.
• Corrosion-Resistant Housing: Standard case manufactured from AISI 303 or AISI 304 stainless steel to ensure longevity in demanding industrial field environments.
• System Interchangeability: Fully compatible with standard 3300 XL Proximitor Sensors and extension cables, maintaining a linear scale factor of 7.87 V/mm (200 mV/mil).

Applications

• Radial shaft vibration and dynamic motion analysis in high-speed industrial turbomachinery.
• Thrust position and axial shaft displacement monitoring within steam and gas turbines.
• Phase reference and shaft speed sensing (Keyphasor) on heavy-duty compressors and generators.
• Vibration monitoring programs in petrochemical plants, refineries, marine propulsion units, and power generation facilities.

Alternative Models & Compatibility

The 330104 series represents the smooth-case version of the standard threaded 330101 (fractional thread) and 330103 (metric thread) probes. When replacing older 3300 series non-XL 8 mm probes with the 330104-00-14-10-02-00, verify that the connected extension cable and Proximitor sensor are also upgraded to 3300 XL variants. Mixing XL and non-XL system components can cause non-linear scale factor errors, typically violating the required 200 mV/mil output specification.

Application Pitfalls & Engineering Notes

Because this is an unthreaded probe with a smooth 140 mm case, it relies entirely on external clamping blocks or mounting sleeves for axial positioning. Ensure that the mounting bracket does not over-tighten on the thin SST case, which can pinch the internal coaxial core and lead to signal attenuation or an open circuit. These probes are factory-calibrated for high-grade AISI 4140 steel targets. Executing measurements on target surfaces made of alternative metals (e.g., stainless steel, aluminum) requires custom calibration adjustments in the Proximitor sensor.

Commissioning & Wiring Tips

Prior to mating, visually inspect the male ClickLoc connector for moisture, dust, or grease. Clean exclusively with isopropyl alcohol and dry thoroughly before connection. Do not use pliers or heavy wrenches to tighten the ClickLoc connection; a finger-tight turn followed by a positive click is sufficient. Wrap the mated connection in self-amalgamating silicone tape to prevent oil ingress in machinery sumps.
