Product Description:

0-5” H2O through 0-5K psdi,
Low Cost Explosion Proof Process TransmitterEx 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
differrential 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 wsere a guaranteed lieak freee system is needed.
Alternate materials for service in corrosive environments
For corrosive environments where 316L is not the material of choice, the
EXD is available in Hasteloy C276, C22 or Inconel 718.
