Reproducibility ≤ ± 1 mm
Deviation with bulk solids The values depend to a great extent on the
application. Binding specifications are thus not
possible.
Variables influencing measurement accuracy
Specifications apply to the HART signal and the current output
Temperature drift - Digital output ± 3 mm/10 K relating to the max. measuring range
or max. 10 mm
Additional deviation through strong, high
frequency electromagnetic fields acc. to EN
61326 <± 50 mm
