Influence of the product or ambient temperature
Average temperature coefficient of the zero signal and the output span
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.
Nominal measuring range in
bar/kPa
Nominal
measuring
range in psig
Average temperature co-
efficient of the zero signal
and the output span, in
the compensated temper-
ature range 0 … +100 °C
(+32 … +212 °F), reference
temperature 20 °C (68 °F)
Average temperature coeffi-
cient of the zero signal and
the output span, outside
