Determination of characteristics Limit point adjustment according to IEC 61298-2
Characterstic curve Linear
Reference installation position upright, diaphragm points downward
Influence of the installation position < 0.2 mbar/20 Pa (0.003 psig)
Deviation (according to IEC 60770)
Applies to the digital signal output (HART, Profibus PA, Foundation Fieldbus) as well as to the
analogue current output 4 … 20 mA and refers to the set span. Turn down (TD) is the ratio nominal
measuring range/set span.
The specified values correspond to the value F

in chapter "Calculation of the total deviation".
Accuracy class Non-linearity, hysteresis and re-
peatability with TD 1 : 1 up to 5 : 1
Non-linearity, hysteresis and re-
peatability with 5 : 1
0.05 % < 0.05 % < 0.01 % x TD
0.1 % < 0.1 % < 0.02 % x TD
0.2 % < 0.2 % < 0.04 % x TD
Influence of the product or ambient temperature
Thermal change zero signal and output span
Applies to the digital signal output (HART, Profibus PA, Foundation Fieldbus) as well as to the
analogue current output 4 … 20 mA and refers to the set span. Turn down (TD) is the ratio nominal
measuring range/set span.
The thermal change of zero signal and output span corresponds to the value F
T
in chapter "Calcu-
lation of the total deviation (according to DIN 16086)".
