La structure tridimensionnelle de ce capteur MEMS est basée sur la mesure de capacité permettant une très grande sensibilité et une excellente stabilité d’offset. L’amortissement interne à gaz inerte fournit un filtre passe-bas mécanique qui coupe au-dessus de 115 Hz et délivre une sortie à amplitude stable et un filtrage des bruits.
\nComme il utilise une sortie analogique, ce circuit peut être placé à bonne distance de l’unité de commande sans créer de parasites en sortie de capteur. Cette flexibilité de montage est bien adaptée pour les suspensions à commande électrique puisqu’elle permet de positionner les capteurs là où on le souhaite, sans avoir à se préoccuper de la longueur des connexions.
\nLa mesure du déplacement selon l’axe Z est rendue possible grâce au capteur spécial propriétaire. En effet, il suffit de monter l’élément à plat sur une carte orientée parallèlement au véhicule. La gravité terrestre est compensée par un décalage de +1 g, où la tension Vout est égale à +2.5 VCC. La plage de mesure est de 2,11g dans les deux sens, ce qui donne une Vout de 0 à +5 VCC.
\nPour faciliter la fabrication et les tests, toutes les données de process et de test de l’ASIC et du capteur MEMS sont traçables au moyen du code-barres 2D apposé sur le dessus du module. Le capteur a été validé conforme à la très stricte norme de qualification des pièces automobiles AEC-Q100. <\/p>\n<\/p>\n
