HygienicMaster – Material load for process connections 
 
The limits of the permissible measuring medium temperature 
(T
medium
) and permissible pressure (P
medium
) are calculated on 
the basis of the liner and flange material used in the device (see 
device name plate). 
 
 
Minimum permissible operating pressure 
 
The following tables show the permissible minimum operating 
pressure (P
medium
) as a function of the measuring medium 
temperature (T
medium
) and the liner material.
