WIKA IPT-11 - Manual (Page 46)

Influence of the product or ambient temperature
Applies to instruments with digital signal output (HART, Profibus PA, Foundation Fieldbus) as well
as to instruments with analogue current output 4 … 20 mA. Specifications refer to the set span.
Turn down (TD) = nominal measuring range/set span.
Thermal change zero zignal, reference temperature 20 °C (68 °F):
-
In the compensated temperature range
0 … +100 °C (+32 … +212 °F) < 0.05 %/10 K x TD
-
Outside the compensated temperature
range typ. < 0.05 %/10 K x TD
Applies also to instruments with analogue 4 … 20 mA current output and refers to the set span.
Thermal change, current output < 0.15 % at -40 … +80 °C (-40 … +176 °F)
Long-term stability (similar to DIN 16086, DINV 19259-1 and IEC 60770-1)
Applies to digital interfaces (HART, Profibus PA, Foundation Fieldbus) as well as to analogue
current output 4 … 20 mA. Specifications refer to the set span. Turn down (TD) = nominal
measuring range/set span.
Long-term drift of the zero signal < (0.1 % x TD)/year
