- Turn down > 5 : 1 < 0.05 % x TD
Influence of the product or ambient temperature
Thermal change zero signal and output span
Applies to the digital signal output (HART, Profibus PA, Foundation Fieldbus) as well as to the
analogue current output 4 … 20 mA and refers to the set span. Turn down (TD) is the ratio nominal
measuring range/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)
Thermal change, current output
Applies also to the 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)
Process conditions
The speci fications to the pressure stage and the product temperature are used as an overview.
The speci fications of the type label are applicable.
Pressure stage, process fitting
- Thread 316L, Hastelloy PN 160
- Small flange DN 10 316L PN 1.5
Product temperature depending on the measuring cell seal
- FKM (A+P 70, 16.06) -40 … +120 °C (-40 … +248 °F)
- FFKM (Kalrez 6375) -20 … +120 °C (-4 … +248 °F)
