VEGAPULS 67 • Probus PA
36533-EN-170405
Repeatability ≤ ±1 mm
Deviation with bulk solids The values depend to a great extent on the application.
Binding specications are thus not possible.
Deviation under EMC inuence
≤ ±30 mm
Variablesinuencingmeasurementaccuracy
Temperature drift - Digital output ±3 mm/10 K, max. 10 mm
Additional deviation through electromag-
netic interference acc. to EN 61326
< ±50 mm
