Description
The DIF-C Cell (Pancake) Diaphragm Seal is designed for pressure transmitters and DP transmitters, using a side capillary connection for reliable signal transmission. It is installed between an open process flange and an optional cover flange, making it ideal for contaminated, solidifying, hot, or highly viscous media. With a wide range of materials available for both the body and diaphragm, the DIF-C provides excellent corrosion resistance and process durability.
It also serves as a highly compatible alternative to the WIKA 990.28, offering equivalent specifications for demanding industrial applications such as chemical processing, petrochemical systems, sludge tanks, and heavy-duty pipelines.
