Ʋ In the compensated temperature

range 0 … +100 °C (+32 … +212 °F)

< (0.1 % + 0.1 % x TD)

Ʋ Outside the compensated tempera-

ture 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.

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 Standard version
