Industrial Applications
The Bently Nevada 330707-00-62-90-02-00 excels in environments where temperature extremes and mechanical stress threaten sensor reliability. Common applications include:
-
Power Generation: Turbine shaft vibration monitoring in gas and steam turbines.
-
Oil & Gas: Compressor and pump condition monitoring in refineries.
-
Petrochemical: Critical rotating equipment surveillance in processing plants.
Its PPS tip and 304 SST case resist corrosion and thermal cycling, ensuring long service life. The 330707-00-62-90-02-00 integrates seamlessly with Bently Nevada monitoring systems.
Installation Guidelines
Proper installation of the 330707-00-62-90-02-00 ensures accurate readings. Use a 5/8-18 UNF threaded mounting hole. Engage the thread to a maximum depth of 0.938 in. Apply recommended torque of 15.2 N•m (133 in•lb) to avoid damaging the probe case or thread. For the connector, finger-tighten to a maximum of 0.565 N•m (5 in•lb). Ensure the cable has a minimum bend radius of 25.4 mm (1.0 in) to prevent internal damage. The probe seals the differential pressure between tip and case using a Viton O-ring; avoid exposing the seal to temperatures below -34°C (30°F) which may cause premature failure.
Maintenance and Reliability
Regularly inspect the cable and connector of the 330707-00-62-90-02-00 for signs of wear or damage. Check the probe resistance at the connector: for a 9-meter probe, the center conductor to outer conductor resistance should be 8.5 ± 1.1 ohms. Monitor operating temperature: prolonged exposure beyond -51°C to +177°C can degrade the PPS tip or cable insulation. The Viton O-ring maintains pressure integrity, but if the probe is subjected to severe thermal cycling, consider periodic replacement. UBEST Automation recommends storing the probe in a clean, dry environment when not in use.
