These specifications ensure the 330709-000-230-50-02-00 performs reliably under mechanical stress and temperature extremes.
Industry Applications
In critical rotating equipment such as turbines, compressors, and pumps, the Bently Nevada 330709-000-230-50-02-00 delivers accurate vibration and position sensing. Its temperature schedule supports ambient conditions from -55°C to +232°C depending on temperature classification (T1–T5), making it suitable for gas and dust hazardous areas (EPL Ga, Gc, Dc). For example, in a steam turbine installation, the probe's 5.0 m cable length matches standard Proximitor sensor distances, while the high-temperature rating handles near-bearing environments.
Installation & Setup Guidance
Proper installation of the Bently Nevada 330709-000-230-50-02-00 ensures optimal performance. Tighten the M16x1.5 probe case to the recommended torque of 21.1 N·m (187 in·lb) — never exceed 63.3 N·m. Use only finger tight for the connector-to-connector joint to avoid damage. Observe a minimum bend radius of 25.4 mm for the cable. For cross-talk avoidance, maintain a minimum target flat surface diameter of 30.5 mm and a shaft diameter of at least 152 mm. The probe cable is 75 Ω triaxial with fluorocarbon (FEP) insulation.
Maintenance & Reliability
Routine inspection of the Bently Nevada 330709-000-230-50-02-00 should focus on cable integrity and connector cleanliness. The PPS tip and stainless steel case resist corrosion and wear. Avoid exposing the probe to temperatures below -34°C (-30°F) for extended periods, as this may cause pressure seal failure. The temperature schedule provides clear operational limits for various ambient conditions. Regular calibration checks against known gap voltages ensure continued accuracy.
Selection Guide & Purchasing Advice
When selecting the Bently Nevada 330709-000-230-50-02-00, verify your system's cable length requirement — this probe is designed for 5.0 m Proximitor sensors only. The unthreaded length is 0 mm, overall case length 230 mm, and total length 5.0 m (16.4 ft). Ensure your connector type matches the miniature coaxial ClickLoc.
