Temperature coefficient of a cooling ele-
ment, depending on the diaphragm-ø
0.1 … 1.5 mbar/10 K
Temperature coefficient of a 1 m
long capillary line, depending on the
diaphragm-ø
0.1 … 15 mbar/10 K
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 ratio nominal measuring
range/set span.
Long-term drift of the zero signal
