  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
