Long-term stability (according to DIN 16086 and IEC 60770-1)
Applies to digital HART interface as well as to analogue current output 4 … 20 mA under refer-
ence conditions. Specifications refer to the set span. Turn down (TD) is the relation nominal meas-
uring range/set span.
Long-term drift of the zero signal:
Ʋ For one year < 0.05 % x TD
Ʋ For five years < 0.1 % x TD
Ʋ For ten years < 0.2 % x TD
Ambient conditions
Ambient, storage and transport temperature
Ʋ Version with connection tube -40 … +80 °C (-40 … +176 °F)
Ʋ Version with suspension cable FEP,
PUR
-20 … +80 °C (-4 … +176 °F)
Ʋ Version with suspension cable PE -20 … +60 °C (-4 … +140 °F)
Process conditions
The specifications of the pressure stage and product temperature are used as an overview. The
specifications on the type label are applicable.
Process pressure
Ʋ with measuring ranges 0.1 bar
(1.45 psig) or 0.2 bar (2.9 psig)
max. 15 bar (217.6 psig) or max. 20 bar (290 psig) 13)
13) Limited by the overpressure resistance of the measuring cell.
