Industry Applications
The Bently Nevada 330709-000-080-10-11-05 excels in turbomachinery, compressors, and large motor vibration monitoring. In a typical steam turbine retrofit, this proximity probe directly upgrades older 3300 XL systems, providing improved resistance to temperature extremes and connector reliability. The 1.0-meter cable length suits compact installations, while the multiple agency approvals simplify compliance in hazardous areas.
Installation and Setup Guidance
When mounting the Bently Nevada 330709-000-080-10-11-05, ensure the M16x1.5 thread engages at least 24 mm into the mounting boss. Tighten the probe case to the recommended torque of 21.1 N·m to avoid damage. The ClickLoc connector should be finger-tightened only. For optimum cross-talk performance, maintain the minimum target and shaft diameters specified. Route the FluidLoc cable with a bend radius no less than 25.4 mm. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.
Selection Guide and Purchasing Advice
Before purchasing the Bently Nevada 330709-000-080-10-11-05, verify the thread type (M16x1.5) and cable length (1.0 m) match your probe holder requirements. This model is a direct replacement for 3300 XL probes with similar connector options. For additional configurations, contact UBEST Automation for expert guidance.
