permitted medium temperature for diaphragms
The indicated medium temperatures apply only to media
which do not corrode or swell the diaphragm materials.
The behaviour of the medium with respect to the dia-
phragm may be changed by the medium temperature.
The function properties, in particular the service life of the
diaphragm, may deteriorate if the medium temperature
increases.
