Industry Applications
The Bently Nevada 330708-00-10-10-11-05 is engineered for continuous vibration monitoring in steam turbines, centrifugal compressors, and large pumps. Its PPS tip and stainless steel case withstand harsh environments, while the ClickLoc connector simplifies field replacement. For example, in a turbine train upgrade, this probe directly replaces older models without requiring additional hardware, reducing downtime.
Installation & Setup Guidance
Proper installation of the 330708-00-10-10-11-05 ensures accurate readings. Use the recommended torque of 15.2 N·m for the 5/8-18 probe case. Do not exceed the maximum rated torque of 45.2 N·m. For connector-to-connector joints, hand-tighten only; maximum torque is 0.565 N·m. Observe a minimum bend radius of 25.4 mm to prevent cable damage. Install in a location where operating temperature stays within -51°C to +177°C, and avoid exposure below -34°C to protect the pressure seal.
