Industry Applications
The Bently Nevada 330904-00-15-50-02-00 excels in applications requiring reliable proximity sensing. Typical uses include:
-
Process Compressors: Its enhanced chemical resistance allows operation in harsh media environments.
-
Turbomachinery: Monitoring shaft vibration and axial position in turbines and compressors.
-
Rotating Equipment: Providing critical data for predictive maintenance and protection systems.
Its superior side-view characteristics make gapping easier at the same distance from the target, ensuring accurate installation.
Installation & Setup Guidance
Proper installation of the 330904-00-15-50-02-00 ensures optimal performance. Follow these guidelines:
-
Mounting: Use the M8X1 thread with a maximum engagement length of 12 mm. Recommended torque is finger tight; maximum torque is 0.56 N•m (5 in•lb).
-
Connector: The miniature coaxial ClickLoc connector provides secure and quick connection. Ensure it is fully seated.
-
Field Wiring: Use a three-conductor shielded triad cable with 0.2 to 1.5 mm² (16 to 24 AWG) conductors. Maximum length between the Proximitor Sensor and monitor is 305 meters (1000 feet).
-
Gap Setting: Set the gap to 1.0 mm (40 mils) for optimal linearity.
Maintenance & Reliability
Routine maintenance of the 330904-00-15-50-02-00 is straightforward. The stainless steel case and PPS tip resist corrosion and wear. Periodically inspect the cable for damage and ensure connectors remain clean. The probe is designed to seal differential pressure between the tip and case, using a Viton O-ring; however, probes are not pressure tested prior to shipment. For applications requiring a pressure seal test, specify this when ordering.
Compatibility & Integration
The Bently Nevada 330904-00-15-50-02-00 is mechanically and electrically compatible with previous 3300 RAM proximity probes and extension cables. It works seamlessly with Bently Nevada Proximitor sensors and monitoring systems, ensuring easy integration into existing setups. The miniature coaxial ClickLoc connector is standard, and the probe is available in various lengths to suit different installations.
Selection Guide & Purchasing Advice
When ordering the 330904-00-15-50-02-00, verify the unthreaded length (00 mm), overall case length (150 mm), and total length (5.0 m) to match your application. Confirm the connector and cable type (02: miniature coaxial ClickLoc, standard cable) and agency approval options.
