Brand: WIKA Alexander Wiegand SE & Co. KG
Diaphragm seals are used to protect the pressure measuring instrument from aggressive, adhesive, crystallising, corrosive, highly viscous, environmentally hazardous or toxic media. 

A diaphragm made of the appropriate material provides for the separation from the medium to be measured. Thus even the most difficult measuring requirements can be met by combining measuring instruments with diaphragm seals.
Features
  • For cleaning easy to remove.
  • Quick cleaning of measuring point, without residue.
  • Suitable for cleaning out of place (COP).
