Abstract

Linvention concerne lautoétalonnage dun système de capteur décartement à canaux multiples (110), comprenant, dans un mode de réalisation, au moins un capteur (40) destiné à mesurer au moins un signal de paramètre décartement entre un objet stationnaire et un objet en rotation dune machine rotative. La sortie de capteur est traitée en tant que paramètre décartement par une section de correction de décalage (137) configurée pour déterminer une erreur de décalage dans le signal de paramètre décartement, qui est utilisée par un convertisseur de niveau (120). Le convertisseur de niveau est également couplé avec faculté de commutation au signal de paramètre décartement, la sortie du convertisseur de niveau, qui peut être amplifiée et convertie numériquement, étant traitée par un analyseur de niveau de signal (154) pour déterminer un signal de gain de canal.
