Installation & Setup Guidance
Proper mounting of the Bently Nevada 330708-00-10-90-12-00 is critical for accurate readings. Ensure the probe case thread (5/8-18 UNF) engages at least 0.938 inches. Apply the recommended torque of 15.2 N·m (133 in·lb) to avoid damaging the O-ring seal. For connector-to-connector connections, tighten only finger tight (max 0.565 N·m). Maintain a minimum bend radius of 25.4 mm on the cable to prevent internal conductor damage. Use the 75 Ω triaxial FEP cable in lengths of 1, 5, or 9 meters; this model provides 9 meters.
Maintenance & Reliability
The PPS probe tip and 304 SST case offer corrosion resistance in demanding environments. The Viton O-ring seals differential pressure between tip and case. While the probe is not pressure-tested before shipment, regular inspection of the cable and connector for wear is recommended. Operating temperature range from -52°C to +177°C accommodates most industrial conditions. Note: Prolonged exposure below -34°C (-30°F) may degrade the pressure seal. Periodic verification of DC resistance (8.5 ± 1.1 ohms for 9m) helps detect cable degradation early.
Selection Guide & Purchasing Advice
When ordering the Bently Nevada 330708-00-10-90-12-00, verify that the total length option (90 = 9.0 m) matches your installation distance. The unthreaded length is 0 inches and overall case length is 1.0 inch. Agency approval option is 00 (not required). For bulk or custom orders, consult UBEST Automation (ubest101) for availability and pricing. This probe is a direct replacement for legacy 3300 XL series installations.
