Product Introduction
When vibration monitoring probes fail due to cable pull-out or oil ingress, the Bently Nevada 330141-08-90-01-00 delivers robust reliability. This 3300 XL 8 mm Probe with armor features patented TipLoc and CableLoc designs that provide 330 N (75 lbf) pull strength, ensuring a more secure attachment between probe cable and tip. Manufactured in the U.S.A., the probe is part of the 3300 XL series, known for enhanced ruggedness through thicker encapsulation of the probe coil in molded PPS plastic and a larger diameter stainless steel case.
Technical Specifications Breakdown

Industry Applications
The Bently Nevada 330141-08-90-01-00 is designed for critical rotating machinery vibration monitoring, such as turbines, compressors, and pumps in power generation, oil and gas, and petrochemical industries. Its robust construction minimizes failures from physical abuse and environmental exposure. For example, the FluidLoc cable option (available separately) prevents oil leakage through the cable interior, addressing a common failure mode in lubricated systems.
Installation and Setup Guidance
For optimal performance, mount the probe with the specified overall case length of 0.8 inches (08 option) and total cable length of 9.0 meters (29.5 feet) using the miniature coaxial ClickLoc connector with connector protector (option 01). Avoid exposing the probe to temperatures below –34°C (–30°F) to prevent premature failure of the pressure seal. When routing cables, ensure a minimum bend radius to avoid kinking. The probe is not pressure tested prior to shipment, so handle with care during installation.
Maintenance and Reliability
Regular inspection of the probe tip and cable for wear or damage is recommended. The Viton® O-ring provides a differential pressure seal between the tip and case, but periodic verification of seal integrity is advised, especially in high-humidity environments. The Bently Nevada 330141-08-90-01-00 is designed to withstand high vibration and shock, but environmental factors like extreme temperatures (below -52°C or above +177°C for standard probes) may require the extended temperature range option. The patented TipLoc and CableLoc features significantly reduce common failure points, improving long-term reliability.
Selection Guide and Purchasing Advice
When ordering the Bently Nevada 330141-08-90-01-00, verify the required overall case length (08 = 0.8 in), total cable length (90 = 9.0 m), connector type (01 = miniature coaxial ClickLoc), and agency approval (00 = not required). For applications with oil or liquid exposure, consider the optional FluidLoc cable. PLC Source PRO offers genuine Bently Nevada parts with fast shipping. Ensure compatibility with your monitoring system by checking the scale factor and linear range.
