Product Introduction
In hazardous industrial environments, reliable vibration monitoring is critical for asset protection. The Bently Nevada 107770-03-03 Velocity Transducer Housing provides a robust solution, combining the proven 330500 Velomitor sensor with a 21128 housing, pre-installed and rated for CENELEC Zone 1, Group IIC applications. This factory-assembled unit ensures seamless integration and compliance with strict safety standards. The 107770-03-03 is designed for use with cable type A or B in compliance with EN 60079-25, making it versatile for various installations.
Real-World Applications
The Bently Nevada 107770-03-03 is ideal for vibration monitoring on rotating machinery such as compressors, turbines, and pumps in oil & gas, petrochemical, and power generation facilities. Its CENELEC approval allows deployment in Zone 1 and Zone 2 hazardous areas where explosive atmospheres may occur. The pre-assembled design reduces on-site installation time and ensures consistent performance across critical assets.
Installation Guide
The Bently Nevada 107770-03-03 features a 1/2-14 NPT mounting thread option (code 03) and a 1/2-14 NPT explosion-proof cable exit fitting with cable gland seal (code 03). For Zone 0/1 installations, ensure the connected equipment meets the listed entity parameters and that cables comply with EN 60079-25 (type A or B). For Zone 2, verify that supply electrical parameters do not exceed the values specified in the product documentation. Always follow local hazardous area regulations during installation.
Safety and Compliance Information
- RoHS Directive 2011/65/EU compliant
- ATEX/IECEx certified for Zone 0/1: Equipment must be connected to equipment meeting the above entity parameters; cables type A or B per EN 60079-25 must respect cable parameters.
- Zone 2: Supply electrical parameters shall not exceed the values mentioned in the applicable tables.
Maintenance and Reliability
Routine inspection of the Bently Nevada 107770-03-03 should focus on the integrity of the housing seal, the cable gland, and the mounting threads. In harsh environments, periodic checks for corrosion or damage to the explosion-proof fittings are recommended. The unit’s robust construction minimizes unplanned downtime, and factory pre-assembly ensures consistent sensor alignment for accurate vibration readings.
Selection Guide and Purchasing Advice
When ordering the 107770-03-03, confirm that the mounting thread and cable exit options match your application requirements (both are 03 = 1/2-14 NPT). Ensure your system is compatible with the included 330500 Velomitor sensor and 21128 housing. For further technical details or volume pricing, contact UBEST Automation at ubest101.
