1) Recommended Turn down: Max 100:1.
Factory calibration Turn down: Max 20:1, higher on request.
2) The MWP (maximum working pressure; MWP = PN) for the measuring device depends on the weakest element of the components selected with regard to
pressure, i.e. the process connection has to be taken into consideration in addition to the measuring cell. Also observe the pressure-temperature dependency.
For the appropriate standards and further information ä 26.
3) OPL: over pressure limit; depends on the lowest-rated element, with regard to pressure, of the selected components ( ä 26).
4) The minimum operating pressure indicated in the table applies to silicone oil under reference operating conditions.
Minimum operating pressure at 85°C (185°F) for silicone oil: 10 mbar (0,15 psi) (abs)
