Model DSS27M Pressure Gauge per EN 837-1 with Mounted Diaphragm Seal

Brand: WIKA Alexander Wiegand SE & Co. KG
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.
Features
  • Flange with a flush welded diaphragm
  • Robust, all welded design
  • Universal application
