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
