FQ4401 Hazardous-Area Stainless Steel Pressure Transducer
High-accuracy stainless steel pressure transducer designed for gas compression, wellhead equipment, industrial OEM, and other demanding applications.
The FQ4401 is a media-isolated stainless steel pressure transducer designed for demanding and potentially hazardous environments. In addition to rugged all-stainless construction and excellent value, the FQ4401 delivers higher accuracy (±0.25% BFSL) than general-purpose models, making it the preferred choice for gas compression, wellhead monitoring, pipeline equipment, and hydrogen-service applications. Oil-free, weld-free, O-ring-free design. Supplied with Ex ia IIC T6 marking per manufacturer documentation; North American hazardous-location certification is application-dependent.
- ▶Gas compression and storage systems
- ▶Wellhead and pipeline pressure monitoring
- ▶Oil & gas platform equipment
- ▶Higher-accuracy measurement requirements
- ▶Projects requiring hazardous-area design review
For general industrial OEM, water systems, or HVAC applications, review FQ3100 General-Purpose Pressure Transducer.
Hazardous-Area Certification Note
