• For saturated steam applications, use a device with a metal process isolating diaphragm, or
provide a siphon for temperature isolation when installing.
• Pay attention to the process temperature range of the seal. See also the following table.

Applications with changes in temperature
Frequent extreme changes in temperatures can temporarily cause measuring errors. Temperature
compensation takes place after a few minutes. Internal temperature compensation is faster the
smaller the change in temperature and the longer the time interval.
