The probe provides a nominal DC resistance of 9.87 ±0.50 Ω for the 9.0-meter length. Its relative humidity performance shows less than a 3% change in Average Scale Factor when tested at 93% humidity per IEC 68-2-3 for up to 56 days.
Industry Applications
The Bently Nevada 330141-08-90-02-05 is widely used in steam turbines, gas compressors, centrifugal pumps, and large electric motors. Its robust construction and high incremental scale factor (7.87 V/mm) deliver accurate shaft displacement measurements essential for predictive maintenance. The optional FluidLoc cable prevents oil leakage in lubricated machinery, reducing contamination risks.
Installation & Setup Guidance
When installing the Bently Nevada 330141-08-90-02-05, ensure the probe tip is properly positioned within the specified linear range (0.25 mm to 2.0 mm gap). Use mounting brackets suited for 8 mm probes and avoid sharp bends in the cable. The patented CableLoc design provides 330 N pull strength, allowing secure cable routing. Always verify the system extension cable length matches the probe total length option (9.0 meters) to maintain calibration.
Maintenance & Reliability
Routine inspection of the Bently Nevada 330141-08-90-02-05 includes checking the probe tip for wear or contamination, verifying cable integrity, and ensuring connectors are clean and tight. The PPS probe tip resists chemical attack, while the stainless steel case withstands corrosion. Avoid exposing the probe to temperatures below −34°C to protect the pressure seal. With proper care, this probe delivers consistent performance over extended service intervals, reducing total cost of ownership.
Selection Guide & Purchasing Advice
Before purchasing the Bently Nevada 330141-08-90-02-05, verify that your system requires an 8 mm probe with a 9.0-meter cable and the specified approvals (CSA, ATEX, IECEx). Confirm compatibility with your Bently Nevada 3300 XL monitor or third-party vibration monitoring system.
