FQ4401 Stainless Steel Pressure Transducer for Selected Hazardous-Environment Projects
Stainless steel pressure transducer for gas compression, wellhead equipment, industrial OEM, and selected hazardous-environment projects requiring document review.
The FQ4401 is a media-isolated stainless steel pressure transducer for demanding gas, wellhead, pipeline, and industrial OEM applications. Its sensing structure is oil-free, weld-free, and O-ring-free. Manufacturer documentation states an Ex ia IIC T6 marking, but the certificate package, entity parameters, safety barrier, project jurisdiction, and installation approval must be verified before hazardous-location use. Wetted-material compatibility must also be confirmed for each medium and operating condition.
- ▶Gas compression and storage systems
- ▶Wellhead and pipeline pressure monitoring
- ▶Oil & gas platform equipment
- ▶Demanding industrial measurement requirements
- ▶Selected hazardous-environment projects requiring certification and installation review
For general industrial OEM, water systems, or refrigeration applications, review FQ3100 General-Purpose Pressure Transducer.
