D series is a diaphragm seal product combining APT8000 / ADP9000 / ADP9000L transmitter, which designed for the high-viscosity/ granular/ high-temp./ high-corrosivity situation.
D series diaphragm seal assembles Alia pressure/DP transmitter to form direct-mount / capillary-connections style.

 The maximum temperature comes up to 280 oC
 Multiple connection modes - Flange style / Tri-Clamp style
 Multiple diaphragms/alternative connection material
 Vegetable oil can be used for fill fluid for food industry
 Extreme hot and cold temperature
 Stainless Steel with PPC coating capillary
 IDF Tri-Clamp or union screw connection for food industry
 Oil-free treatment & water-free treatment
 Fast and dynamic response
 Improved performance, increased accuracy and great stability
