Industry Applications
The Bently Nevada 330709-000-030-50-11-05 3300 XL 11 mm Proximity Probe is ideal for vibration monitoring on turbines, compressors, pumps, and motors. When replacing older probe types, ensure the 5.0-meter length matches the corresponding Proximitor sensor. This upgrade provides improved accuracy and reliability in harsh environments.
Installation & Setup Guidance
Apply the recommended torque of 21.1 N·m (187 in·lb) for the M16x1.5 probe case. For the connector, finger tight is recommended; do not exceed 0.565 N·m (5 in·lb). Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. Avoid temperatures below -34°C (-30°F) to prevent premature pressure seal failure. Thread engagement must not exceed 24 mm.
Maintenance & Reliability
Regularly inspect the probe cable and connector for damage. Operate within the temperature range of -52°C to +177°C. The robust AISI 304 stainless steel case and PPS tip ensure long service life. Following these practices minimizes downtime and extends probe lifespan.
Selection Guide & Purchasing Advice
Before purchasing, verify that your system uses a five meter Proximitor sensor, as this probe is designed solely for that configuration. Confirm the thread type (M16x1.5) and required approvals. For reliable supply and fast delivery, choose UBEST Automation at ubest101.
