The cable exit fitting (also option 02) uses a 1/2-14 NPT explosion-proof design, which helps maintain safety in hazardous zones. This unit is rated for CENELEC Zone 1, Group IIC areas, meaning it can operate where explosive gases may be present.

Industry Applications

In petrochemical plants, refineries, and gas processing facilities, the 107770-02-02 delivers continuous velocity measurement for rotating equipment like pumps, compressors, and turbines. Its CENELEC approval allows installation in Zone 1 classified areas without additional enclosure modifications. For example, a refinery upgrading its vibration monitoring system can directly mount this transducer housing on critical pumps, reducing installation time and ensuring compliance with ATEX/IECEx requirements.

Installation & Setup Guidance

Mount the 107770-02-02 using the 3/4-14 NPT thread into a compatible mounting boss on the machine casing. Ensure the cable exit fitting (1/2-14 NPT) is properly sealed with approved explosion-proof conduit or cable glands. Follow the manufacturer's guidelines for cable type A or B per EN 60079-25 to maintain entity parameters. For Zone 0/1 installations, verify that the connected equipment meets the listed entity parameters. For Zone 2, ensure supply electrical parameters do not exceed the values in the provided tables.

Maintenance & Reliability

Routine inspection of the transducer housing and cable connections helps maintain reliable operation. Check for signs of corrosion or damage to the explosion-proof fitting. Since the unit is factory-sealed, no internal maintenance is required. Periodic verification of the mounting thread integrity and cable gland tightness is recommended. The 12-month factory warranty provides initial coverage, and Bently Nevada's support network can assist with long-term reliability.

Selection Guide & Purchasing Advice

Before ordering the 107770-02-02, confirm that your application requires a CENELEC-approved velocity transducer housing with 3/4-14 NPT mounting and 1/2-14 NPT cable exit. Verify that the hazardous area classification matches Zone 1, Group IIC. For complete technical specifications, please contact BluePLC Industrial.
