Product Overview
When upgrading vibration monitoring systems in hazardous environments, the Bently Nevada 107770-02-01 Velocity Transducer Housing offers a reliable, pre-integrated solution. This model combines the 330500 Velomitor Sensor with a 21128 Housing, factory-assembled for immediate installation. Rated for CENELEC Zone 1, Group IIC, the 107770-02-01 ensures safe operation in explosive gas atmospheres while reducing field assembly errors.
Industry Applications
The Bently Nevada 107770-02-01 is ideal for continuous vibration monitoring on rotating machinery in oil & gas, chemical processing, and power generation. Its CENELEC approval makes it suitable for use in Zone 1 hazardous areas where flammable gases may be present. Typical applications include monitoring compressors, turbines, and pumps where accurate velocity sensing is critical for predictive maintenance. The factory-integrated design simplifies replacement of older, non-integrated sensor-housing combinations.
Installation & Setup Guidance
Mounting the Bently Nevada 107770-02-01 requires care: the model includes a 3/4-14 NPT mounting thread option (designated as '02') and a 1/2-14 NPT plug for cable exit (option '01'). Ensure the mating surface is clean and free of debris. For hazardous area compliance in Zone 0/1, the equipment must be connected to apparatus meeting entity parameters, and cables of type A or B (per EN 60079-25) must respect listed cable parameters. In Zone 2, supply parameters must not exceed the values in the tables. Always follow local electrical codes.
Compatibility & Integration
The 107770-02-01 integrates directly with Bently Nevada monitoring systems that accept Velomitor sensor signals. The pre-installed 330500 sensor provides a high-level output compatible with standard vibration monitors. The housing itself is designed for direct replacement of older 21128-based assemblies, reducing downtime. For new installations, consult the system manual to verify sensor compatibility.
Selection Guide & Purchasing Advice
Before ordering the Bently Nevada 107770-02-01, verify your hazardous area classification (CENELEC Zone 1, Group IIC) and mounting thread requirements. This specific variant uses a 3/4-14 NPT thread and 1/2-14 NPT cable plug. If you need different thread options, contact PLC Source PRO for guidance.
