EXD Series Explosion Proof Transmitter

0-5 inwc through 0-5K psid

Certified for Hazardous Locations

EX approved for hazardous locations

Dylix’s EXD Series Differential Pressure Transmitter is designed and approved for use in hazardous locations. The EXD’s entirely welded 316L SST construction is hermetically sealed, making it ideal for the worst of pressure applications. CSA/CUS Explosion Proof certified for Class I Div 1 and Class I Div 2 Groups A, B, C, D.

Manufactured for extended life cycles

The EXD is built using advanced manufacturing techniques to ensure symmetry between the Hi and Lo ports. Symmetry, along with automated welding procedures and extreme environmental burn-in, give Dylix’s differential pressure products excellent performance and reliability over time and at high elevated line pressure.

Entirely welded 316L SST pressure cavities

The EXD’s pressure ports all welded 316L SST ‘O’-Ring free design makes it ideal for high cyclical applications, capillary filled systems, or applications where a guaranteed leak free system is needed.
