Product Introduction
When rotating machinery experiences vibration probe failures due to cable pull or oil leakage, downtime becomes inevitable. The Bently Nevada 330141-08-90-12-05 3300 XL 8 mm Probe with armor addresses these challenges with patented CableLoc and FluidLoc technologies. This industrial automation probe delivers robust performance in harsh environments, providing reliable vibration monitoring for critical assets like turbines, compressors, and pumps.

Real-World Applications
The 330141-08-90-12-05 excels in environments where cable integrity and fluid resistance are paramount. Typical applications include:
- Steam and gas turbine vibration monitoring in power generation
- Compressor condition monitoring in oil & gas processing
- Pump health monitoring in chemical and petrochemical plants
Installation & Setup Guidance
When installing the Bently Nevada 330141-08-90-12-05, ensure the probe tip is properly engaged using the patented TipLoc molding method. For installations exposed to liquids, select the FluidLoc cable option to prevent oil leakage. Avoid exposing the probe to temperatures below –34°C (–30°F) as this may cause premature failure of the pressure seal. The probe is designed to seal differential pressure between tip and case via a Viton O-ring; however, probes are not pressure tested prior to shipment.
Maintenance & Reliability
Regularly inspect the miniature coaxial ClickLoc connector for signs of wear or corrosion. The 3300 XL probe's CableLoc design provides 330 N (75 lbf) pull strength, reducing the risk of cable disconnection. In high-humidity environments, the probe maintains less than 3% change in average scale factor, ensuring consistent performance. For extended temperature applications, use the ETR-rated probe to withstand tip temperatures up to 218°C.
Selection Guide & Purchasing Advice
Before ordering, verify the total length option (9.0 meters) and connector type (ClickLoc with FluidLoc) match your installation requirements. The 05 agency approval option includes CSA, ATEX, and IECEx certifications. This probe is intended for use with Bently Nevada 3300 XL monitoring systems.
