1) OPL: overpressure limit
2) The MWP (maximum working pressure) for the measuring device depends on the element of the selected components which has the lowest pressure
rating, i.e. the process connection (
→ see Page 31 ff) has to be taken into consideration in addition to the measuring cell (→ see Table above). Please also
observe the pressure-temperature dependencies. For the appropriate standards and further information, see Page 30, "Pressure specifications" section.
