Abstract

L'INVENTION CONCERNE UN DISPOSITIF TRANSDUCTEUR ELECTRIQUE, NOTAMMENT UN CAPTEUR. LE TRANSDUCTEUR PROPREMENT DIT POSSEDE UNE LOI DE TRANSFORMATION ENTRE UNE GRANDEUR PHYSIQUE ET UNE GRANDEUR ELECTRIQUE, LOI CONNUE MAIS AFFECTEE PAR UN PARAMETRE IMPREVISIBLE LORS DE LA CONSTRUCTION DU TRANSDUCTEUR ET CEPENDANT MESURABLE. UN COMPOSANT ELECTRIQUE TEL QU'UNE RESISTANCE EST FIXE SUR LE TRANSDUCTEUR POUR REPRESENTER UNE MESURE DE CE PARAMETRE IMPREVISIBLE. LE TRANSDUCTEUR EST COUPLE A UN CIRCUIT DE TRAITEMENT ELECTRIQUE QUI EST EGALEMENT CONNECTE AU COMPOSANT ELECTRONIQUE EN VUE DE CORRIGER LA LOI DE TRANSFORMATION DU TRANSDUCTEUR EN RAMENANT CELLE-CI A UNE LOI NOMINALE. APPLICATION: CAPTEURS DE NIVEAU DE CARBURANT D'UN VEHICULE.THE INVENTION RELATES TO AN ELECTRICAL TRANSDUCER DEVICE, IN PARTICULAR A SENSOR. THE TRANSDUCER PROPERLY SAYS HAS A LAW OF TRANSFORMATION BETWEEN A PHYSICAL SIZE AND AN ELECTRICAL SIZE, A LAW KNOWN BUT AFFECTED BY AN UNPREDICTABLE PARAMETER DURING THE CONSTRUCTION OF THE TRANSDUCER AND HOWEVER MEASURABLE. AN ELECTRICAL COMPONENT SUCH AS A RESISTOR IS FIXED ON THE TRANSDUCER TO REPRESENT A MEASUREMENT OF THIS UNPREDICTABLE PARAMETER. THE TRANSDUCER IS COUPLED TO AN ELECTRICAL PROCESSING CIRCUIT WHICH IS ALSO CONNECTED TO THE ELECTRONIC COMPONENT IN ORDER TO CORRECT THE TRANSFORMATION LAW OF THE TRANSDUCER BY RETURNING THIS TO A NOMINAL LAW. APPLICATION: VEHICLE FUEL LEVEL SENSORS.
