A variable reluctance transducer system incorporating digital control of parallel resonant circuits (L1C1, L2C1) including two inductive sensors (L1, L2) on each side of a flat diaphragm. The two parallel resonant circuits provide dual frequency signals for digital calculation to obtain a quotient of the frequencies, thereby substantially eliminating the resonant frequencies as a variable in the accuracy of the device. Manipulation of the produced quotient by a microcontroller (10) employing digital calibration tables stored in a programmable read only memory (14) allows calibration responsive to a temperature sensor (16), thereby substantially eliminating temperature induced error in the system.

Système transducteur à reluctance variable, comportant une commande numérique de circuits résonants parallèles (L1C1, L2C1) comprenant deux capteurs inductifs (L1, L2) de part et d'autre d'un diaphragme plat. Les deux circuits résonants parallèles fournissent des signaux de fréquence double pour le calcul numérique nécessaire à l'obtention d'un quotient des fréquences, permettant ainsi essentiellement d'éliminer les fréquences résonantes en tant que variables pour la précision du dispositif. Le traitement du quotient produit par un micro-contrôleur (10) employant des tables d'étalonnage numériques stockées dans une mémoire programmable à lecture seule (14) assure une réaction d'étalonnage à un capteur de température (16), permettant ainsi essentiellement de supprimer l'erreur induite par la température dans le système.
