Abstract

On décrit un système de mesure de la pression plus précis que le capteur ou transducteur de pression incorporé dans le système. Le système inclut un manostat et un capteur ou transducteur de pression, chacun desdits éléments pouvant être mis en oeuvre pour détecter la pression dans un récipient, une ligne fluidique, ou analogue. Le manostat comprend un point de réglage présélectionné, si bien que le passage de la pression en cours de détection au point de réglage déclenche le manostat. Un circuit surveille le capteur et le manostat de sorte que le déclenchement de ce dernier permet au circuit de déterminer une erreur éventuelle de lecture depuis le capteur, et corrige les lectures ultérieures depuis le capteur, sur la base de la valeur de l'erreur calculée.
