VEGA VEGABAR 63 Profibus PA - Manual (Page 54)

Deviation with absolute pressure measuring range 0.1 bar
-
Turn down 1 : 1 up to 5 : 1 < 0.25 %
-
Turn down > 5 : 1 < 0.05 % x TD
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
