Industry Applications
This Bently Nevada 330191-00-40-05-CN probe excels in vibration monitoring for steam turbines, centrifugal compressors, and large electric motors. Its robust design withstands harsh industrial environments, providing accurate displacement measurements. The upgrade from older probes reduces maintenance intervals and improves reliability. In oil and gas facilities, the optional FluidLoc cable prevents oil leaks, making it a safer choice.
Installation & Setup Guidance
Mount the probe with the 3/8-24 UNF thread, ensuring the maximum thread engagement length of 0.563 in is not exceeded. Apply a maximum connector torque of 0.565 N·m (5 in·lbf). The probe features a Viton O-ring seal for differential pressure. Use only BN extension cables to maintain entity parameters. For optimal performance, avoid operating at voltages more positive than -23.5 Vdc, as this may reduce linear range.
Selection Guide & Purchasing Advice
When selecting this probe, confirm the total length option: 05 indicates 0.5 meter. The CN country-specific version includes agency approvals. For armored or extended temperature cable options, refer to the ordering code. PLC Source PRO offers new and original factory-packed units with a 12-month warranty, ensuring genuine parts for your critical systems.
