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 zignal, reference temperature 20 °C (68 °F):
