Applications and Failure Mode Prevention
The Bently Nevada 330708-00-10-90-12-05 is designed to prevent common failure modes in vibration monitoring. In turbines, where shaft vibration can cause catastrophic bearing damage, this probe's rugged construction and wide temperature range (-51°C to +177°C) ensure reliable readings even near hot steam paths. Its PPS tip resists chemical attack, while the 304 SST case withstands mechanical stress. The FluidLoc cable eliminates moisture ingress, a frequent cause of signal drift.
Installation and Setup Guidance
Proper installation of the Bently Nevada 330708-00-10-90-12-05 is critical for accurate data. Use a 5/8-18 UNF thread with a maximum engagement of 0.938 inches. Apply recommended torque of 15.2 N·m (133 in·lb); do not exceed 45.2 N·m (400 in·lb). For the connector, tighten finger tight only (maximum 0.565 N·m or 5 in·lb). Minimum cable bend radius is 25.4 mm (1.0 in). Ensure the probe tip is not exposed to temperatures below -34°C (-30°F) to avoid premature pressure seal failure.
Selection and Purchasing Advice
When selecting the Bently Nevada 330708-00-10-90-12-05, verify your thread type (5/8-18 UNF) and total length requirement (9.0 m). This probe is ideal for installations requiring a 11 mm proximity sensor with a robust cable and connector. For alternative lengths or armor options, consult the product catalog.
