Air pressure
860 … 1060 mbar/86 … 106 kPa (12.5 … 15.4 psi)
Determination of characteristics
Limit point adjustment according to IEC 61298-2
Characteristic curve
Linear
Reference installation position
upright, diaphragm points downward
Influence of the installation position

-
ing cell
depending on the process fitting and the chemical seal
Ʋ
Ceramic/metallic measuring cell
< 5 mbar/0.5 kPa (0.07 psig)
Deviation in the current output due to
strong, high-frequency electromagnetic
fields acc. to EN 61326-1
< ±150 µA
Deviation (according to IEC 60770-1)
Applies to the
digital
signal output (HART, Profibus PA, Foundation Fieldbus) as well as to the
ana-
logue
current output 4 … 20 mA and refers to the set span. Turn down (TD) is the ratio "nominal
measuring range/set span".
