Model DSS18F Pressure Gauge per EN 837-1 with Mounted Diaphragm Seal

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
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
  • Quick cleaning, without residue.
  • Milk thread fitting per DIN 11851.
  • Suitable for cleaning out of place (COP).
