Industry Applications: Protecting Critical Assets
This probe is engineered for continuous vibration monitoring on turbines, compressors, pumps, and fans. Its 2 mm linear range and high sensitivity (7.87 V/mm) enable early detection of shaft displacement, imbalance, and misalignment. The patented TipLoc and CableLoc designs provide 330 N (75 lbf) pull strength, reducing the risk of cable failure in high-vibration environments. Maintenance teams benefit from fewer false trips and longer service intervals.
Installation & Setup Guidance
When installing the 330101-00-84-20-02-05, ensure the probe tip is clean and the mounting surface is free of debris. Use the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration measurements. The 3/8-24 UNF thread allows secure mounting in standard ports. For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable, keeping runs under 305 meters (1,000 feet) to avoid signal roll-off at high frequencies.
Maintenance & Reliability
Inspect the probe cable and connector periodically for signs of wear or damage. The stainless steel case and PPS tip resist corrosion and physical abuse. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The FluidLoc cable option can be ordered to prevent oil leakage through the cable interior in lubricated machinery.
Compatibility & Integration
The 330101-00-84-20-02-05 is designed for use with Bently Nevada 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector ensures a reliable, quick connection. The probe carries CSA, ATEX, and IECEx approvals, making it suitable for hazardous area installations. Verify system compatibility before ordering.
Selection Guide & Purchasing Advice
When selecting a replacement probe, confirm the thread size (3/8-24 UNF), overall case length (8.4 in), and total cable length (2.0 m). The 330101-00-84-20-02-05 is a non-armored version; if additional mechanical protection is needed, consider an armored variant.
