1) Recommended Turn down: Max 100:1.
Factory calibration Turn down: Max 20:1, higher on request.
2) The MWP (maximum working pressure) for the measuring device depends on the lowest-rated element, with regard to pressure, of the selected components,
i.e. the process connection (→ ä 30 ff) has to be taken into consideration in addition to the measuring cell (→ see Table above). Pay attention to the pressure-
temperature dependence also. For the appropriate standards and other information, see → ä 29, Pressure specifications section.
3) OPL: over pressure limit; depends on the lowest-rated element, with regard to pressure, of the selected components
4) The vacuum resistance applies to the measuring cell at reference conditions.
5) → ä 53 ff, "Ordering information" section, feature 70 "Sensor range"
6) By default, the device is set to a lower range limit of 0 bar. Please specify in the order if the lower range limit is to be set to a different default value.
