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. Due to its design, the DSS10M can be used universally. A replacement of the lower body is possible (e.g. when changing the process connection) without having to carry out modifications on the diaphragm seal system.
