Diaphragm seal systems are used to protect the pressure measuring instrument from aggressive, adhesive, crystallising, corrosive, highly viscous, environmentally hazardous or toxic media. The diaphragm made of stainless steel provides for the separation from the medium. The pressure is transmitted to the measuring instrument via the system fill fluid which is inside the diaphragm seal system. The DSS27M with flange connection and flush diaphragm is available following currently used, international flange standards.

Mounting of the diaphragm seal to the measuring instrument is made via direct mounting as standard. The DSS27M is particularly well suited for aggressive, highly viscous, crystallising or hot media. The measuring system is successfully used worldwide in the chemical process and petrochemical industries with high measuring requirements.
