Product Overview
When monitoring vibration in hazardous industrial environments, the Bently Nevada 107770-04-01 Velocity Transducer Housing delivers reliable performance. This factory-assembled unit combines the 330500 Velomitor Sensor with a 21128 Housing, preconfigured for CENELEC Zone 1, Group IIC hazardous area applications. The 107770-04-01 provides a robust solution for continuous vibration monitoring in explosive atmospheres.
Key Specifications
The 107770-04-01 features a mounting thread option of 1/2-14 BSP and a cable exit fitting option of 1/2-14 NPT plug. It complies with ATEX/IECEx standards for Zone 0/1 and Zone 2 hazardous areas. The equipment must connect to systems meeting the listed entity parameters, and cables type A or B per EN 60079-25 must respect those parameters. For Zone 2, supply electrical parameters must not exceed the values in the tables. The unit is RoHS compliant per Directive 2011/65/EU.
Industry Applications
In petrochemical plants, the 107770-04-01 monitors rotating machinery such as pumps and compressors in Zone 1 areas. Its CENELEC approval ensures safe operation in explosive gas environments. For refineries, this housing provides reliable vibration data for predictive maintenance, helping prevent unplanned downtime. The factory preassembly reduces installation complexity and ensures consistent performance.
Installation & Setup Guidance
Mount the 107770-04-01 using the 1/2-14 BSP thread option. Ensure the cable exit fitting uses the 1/2-14 NPT plug. For Zone 0/1 installations, connect the equipment to systems that meet the entity parameters. Use cables type A or B in compliance with EN 60079-25. Verify that supply electrical parameters do not exceed the values in the hazardous area tables for Zone 2.
Maintenance & Reliability
Regularly inspect the housing for signs of corrosion or damage. Verify cable connections and ensure the cable exit fitting remains secure. The factory-assembled design minimizes potential failure points. Following the manufacturer's guidelines for periodic testing helps maintain reliable operation in hazardous environments.
Compatibility & Integration
The 107770-04-01 integrates with Bently Nevada monitoring systems that accept velocity transducer inputs. It works with vibration monitoring platforms used in industrial automation. Ensure the monitoring system supports the entity parameters required for hazardous area compliance.
