What Is the Bently Nevada 107770-01-02?
When you need reliable vibration monitoring in hazardous environments, the Bently Nevada 107770-01-02 delivers a factory-assembled solution. This velocity transducer housing combines a 330500 Velomitor Sensor with a 21128 Housing, preinstalled and tested at the factory. It is rated for CENELEC Zone 1, Group IIC hazardous area applications, making it suitable for demanding industrial settings like oil refineries and chemical plants.
Technical Specifications Breakdown
The 107770-01-02 model includes specific configuration options that define its use. The mounting thread option "01" indicates an unthreaded design, simplifying installation in certain brackets or fixtures. The cable exit fitting option "02" specifies a 1/2-14 NPT explosion-proof fitting, ensuring a secure and safe connection in explosive atmospheres. This version complies with ATEX/IECEx standards for Zone 0/1 and Zone 2 areas, with entity parameters that must be respected during connection.
Industry Applications
This velocity transducer housing is ideal for continuous vibration monitoring on rotating machinery such as pumps, compressors, and turbines in hazardous locations. In a refinery, for example, the CENELEC Zone 1 rating allows installation directly on equipment handling flammable gases. The factory-assembled design reduces field wiring errors and speeds up deployment, minimizing downtime during installation.
Installation & Setup Guidance
When installing the 107770-01-02, ensure the equipment meets the listed entity parameters for safe use. For Zone 0/1 areas, use cable type A or B in compliance with EN 60079-25, respecting the specified cable parameters. For Zone 2, the supply electrical parameters must not exceed the values in the provided tables. Mount the housing securely using the unthreaded option, and connect the explosion-proof cable fitting to maintain the integrity of the hazardous area seal.
Maintenance & Reliability
Routine inspection of the cable connections and housing integrity is recommended to maintain long-term reliability. The factory-sealed assembly reduces the risk of contamination or moisture ingress, extending service life in harsh environments. Periodic verification of the entity parameters against the connected equipment ensures continued safe operation.
Compatibility & Integration
The 107770-01-02 integrates seamlessly with Bently Nevada monitoring systems that accept velocity transducer inputs. It is designed for use with the 330500 Velomitor Sensor, providing consistent performance across the measurement chain. The CENELEC approval ensures compatibility with European hazardous area regulations, simplifying compliance for international projects.
Buying Guide & Purchasing Advice
Before ordering, verify that your application requires a CENELEC Zone 1, Group IIC rated housing with an unthreaded mount and 1/2-14 NPT explosion-proof cable exit.
