Influence of the product or ambient temperature
A pplies 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.
T
urn down (TD) = nominal measuring range/set span.
T hermal change zero signal and output span, reference temperature 20 °C (68 °F):
-
I n the compensated temperature range
0 … +100 °C (+32 … +212 °F)
< (0.05 % + 0.1 % x TD)
-
O utside the compensated temperature
range
< (0.05 % + 0.15 % x TD)
A
pplies also to instruments with analogue 4 … 20 mA current output and refers to the set span.
T hermal 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)
A
pplies 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.
