Influence of the installation position < 5 mbar/0.5 kPa (0.07 psig)
Deviation determined according to the limit point method according to IEC 60770 12)
Applies to the digital signal output (HART, Profibus PA, Foundation Fieldbus) as well as to ana-
logue current output 4 … 20 mA and refers to the set span. Turn down (TD) is the ratio nominal
measuring range/set span.
Deviation
