By using diaphragm seals, the measuring instruments can be used at extreme temperatures from -90 to +400 °C and with aggressive, corrosive, heterogeneous, abrasive, highly viscous or toxic media.

FAQ

When are threaded connections used with diaphragm seals?

The combinations of diaphragm seals with threaded connection can be used for processes with extreme temperatures and with aggressive, adhesive, corrosive, environmentally hazardous or toxic media.

What influence does the diameter of the diaphragm have on the display?

Diaphragms with small diameters can only measure small volume changes. The larger the diameter of a diaphragm, the better the deviations that occur can be compensated for.
