Industry Applications
The Bently Nevada 107770-03-02 excels in continuous vibration monitoring for rotating machinery in hazardous areas. Typical applications include compressors, pumps, turbines, and fans in oil refineries, chemical plants, and gas processing facilities. Its CENELEC certification ensures safe operation in Zone 1 explosive atmospheres. By replacing older separate sensor and housing setups with this complete assembly, you reduce installation complexity and potential points of failure.
Installation & Setup Guidance
Mount the Bently Nevada 107770-03-02 using the 1/2-14 NPT mounting thread. The cable exit fitting is also 1/2-14 NPT explosion-proof, requiring a suitable conduit or cable gland. Ensure that the connection equipment meets the entity parameters listed in the safe use conditions for Zone 0/1/2. For zone 0/1, use cable types A or B per EN 60079-25. All terminations must comply with local hazardous area installation standards. Prewiring the sensor at the factory reduces on-site wiring errors.
Compatibility & Integration
The Bently Nevada 107770-03-02 is designed to work seamlessly with Bently Nevada monitoring systems that accept velocity transducer inputs. The 330500 Velomitor core provides a reliable velocity signal for machinery protection and condition monitoring. The assembly mounts directly on equipment using standard 1/2-14 NPT ports, making it a drop-in replacement for many existing installations.
Selection Guide
Before purchasing the Bently Nevada 107770-03-02, verify your mounting thread and cable exit requirements. This model uses a 1/2-14 NPT thread with an explosion-proof cable fitting. Confirm that your system is compatible with the factory-installed sensor and housing configuration. For assistance selecting the correct variant, contact UBEST Automation.
