Influence of the installation position < 0.2 mbar/20 Pa (0.003 psig)
Deviation determined according to the limit point method according to IEC 60770
10)
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) is the relation
nominal measuring range/set span.
Deviation
- Turn down 1 : 1 up to 5 : 1 < 0.075 %
- Turn down > 5 : 1 < 0.015 % x TD
Deviation with absolute pressure measuring range 0.1 bar
- Turn down 1 : 1 up to 5 : 1 < 0.25 % x TD
- Turn down > 5 : 1 < 0.05 % x TD
Influence of the product or ambient temperature
Applies also to instruments with analogue 4 … 20 mA current output and refers to the set span.
Thermal change zero signal and output span, reference temperature 20 °C (68 °F):
- In the compensated temperature range
0 … +100 °C (+32 … +212 °F)
< (0.05 % + 0.1 % x TD)
- Outside the compensated temperature
range
< (0.05 % + 0.15 % x TD)
Thermal change zero signal and output span with absolute pressure measuring range 0.1 bar,
reference temperature 20 °C (68 °F ):
- In the compensated temperature range
0 … +100 °C (+32 … +212 °F)
< (0.1 % + 0.1 % x TD)
- Outside the compensated temperature
range
< (0.15 % + 0.15 % 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
Ambient conditions
Ambient, storage and transport temperature -40 … +80 °C (-40 … +176 °F)
