Industry Applications
The Bently Nevada 330708-00-10-90-11-05 is ideal for upgrading vibration monitoring systems on steam turbines, centrifugal compressors, pumps, and fans. Its 11 mm tip and 9-meter cable suit installations with limited access. The wide temperature range ensures reliable operation in harsh environments. Replacing older probes with this model improves measurement accuracy and reduces maintenance frequency.
Installation & Setup Guidance
Install the Bently Nevada 330708-00-10-90-11-05 by threading into a 5/8-18 UNF mounting hole. Apply the recommended torque of 15.2 N·m to avoid damaging the probe case. Use finger tight for the ClickLoc connector, with a maximum of 0.565 N·m. Ensure the cable bend radius remains above 25.4 mm to prevent damage. Verify the probe gap per system requirements for optimal linearity.
Maintenance & Reliability
Periodically inspect the cable and connector for wear or damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to preserve the pressure seal. The PPS tip and SST case resist corrosion and wear, extending service life. Regular calibration checks help maintain measurement integrity. Following these steps maximizes uptime and reduces total cost of ownership.
Selection Guide & Purchasing Advice
Before purchasing the Bently Nevada 330708-00-10-90-11-05, confirm the thread size matches your mounting (5/8-18 UNF). Also verify the cable length (9 m) and agency approval requirements.
