Product Overview
When monitoring critical rotating machinery in hazardous environments, selecting the right transducer housing is essential for both safety and reliability. The Bently Nevada 107770-04-02 Velocity Transducer Housing addresses this challenge directly. This CENELEC approved unit combines a 330500 Velomitor Sensor with a 21128 Housing, preinstalled at the factory, ensuring consistent performance in demanding industrial settings.
Technical Specifications
The 107770-04-02 features a 1/2-14 BSP mounting thread option and a 1/2-14 NPT explosion-proof cable exit fitting. It is rated for CENELEC Zone 1, Group IIC hazardous area applications. The unit complies with RoHS Directive 2011/65/EU and meets ATEX/IECEx requirements for safe use in Zone 0/1 and Zone 2 areas. For Zone 0/1, equipment must connect to devices meeting the listed entity parameters, and cables type A or B (in compliance with EN 60079-25) must respect the specified cable parameters. In Zone 2, supply electrical parameters must not exceed the values in the provided tables.
Industry Applications
In petrochemical plants, refineries, and gas processing facilities, the 107770-04-02 provides reliable vibration monitoring on pumps, compressors, and turbines. Its CENELEC Zone 1, Group IIC rating makes it suitable for environments with explosive gases. The factory-preinstalled 330500 Velomitor Sensor simplifies installation and reduces on-site assembly errors, saving valuable commissioning time.
Installation & Setup Guidance
Mount the housing using the 1/2-14 BSP thread option. Ensure the cable exit fitting uses the 1/2-14 NPT explosion-proof connection. For Zone 0/1 installations, verify that all connected equipment meets the entity parameters listed in the product documentation. Use cables type A or B as defined in EN 60079-25, respecting the specified cable parameters. For Zone 2, confirm that supply parameters do not exceed the values in the provided tables. Always follow the manufacturer's safety manual for hazardous area installations.
Maintenance & Reliability
Periodically inspect the housing and cable connections for signs of wear or damage. Verify that the explosion-proof fitting remains properly sealed. The factory-installed 330500 Velomitor Sensor and 21128 Housing reduce the need for field adjustments, enhancing long-term reliability. Regular testing according to the manufacturer's guidelines helps maintain consistent performance in critical applications.
Compatibility & Integration
The 107770-04-02 integrates with Bently Nevada monitoring systems and other compatible vibration monitoring equipment. The 1/2-14 NPT explosion-proof cable exit fitting allows connection to standard industrial cabling. Ensure that any connected equipment meets the entity parameters for Zone 0/1 or the supply limits for Zone 2 as specified in the product documentation.
Selection Guide & Purchasing Advice
Before ordering, verify that the mounting thread (1/2-14 BSP) and cable exit fitting (1/2-14 NPT explosion-proof) match your installation requirements. Confirm that the CENELEC Zone 1, Group IIC rating suits your hazardous area classification.
