Description

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 DSS18F complies with all requirements of the food industry. The milk thread fitting enables a hygienic process connection. The requirements of COP (Cleaning out of Place) are fulfilled.

Special features

  • Quick cleaning, without residue
  • Milk thread fitting per DIN 11851
  • Suitable for cleaning out of place (COP)
