Title

(FR) APPAREIL ET PROCÉDÉS D'AUTO-COMPENSATION AUTOMATISÉE DESTINÉS À FOURNIR DES CAPTEURS ÉLECTROCHIMIQUES
Abstract
(EN)
Systems and methods for automated self-compensation are described herein. Accordingly, some embodiments of a method may include measuring a signal from an electrochemical sensor device, where the signal relates to the presence of a predetermined gas, and where the electrochemical sensor device includes a potentiostat, measuring an internal property of the electrochemical sensor device by electronically pinging the potentiostat, and receiving a response from the potentiostat. In some embodiments, the method may include interpreting the response through an associative relationship between the electrochemical sensor device and a data acquisition and calculation module, determining an effect of an environmental factor from the response, compensating for effects of the environmental factor by adjusting the signal from the electrochemical sensor device and outputting the adjusted signal.

L'invention concerne des systèmes et des procédés destinés à une auto-compensation automatisée. Ainsi, certains modes de réalisation d'un procédé peuvent comprendre la mesure d'un signal en provenance d'un dispositif de capteur électrochimique, le signal concernant la présence d'un gaz prédéterminé, et le dispositif de capteur électrochimique comprenant un potentiostat, la mesure d'une propriété interne du dispositif de capteur électrochimique par envoi électronique de ping au potentiostat, et la réception d'une réponse en provenance du potentiostat. Dans certains modes de réalisation, le procédé peut consister à interpréter la réponse à travers une relation associative entre le dispositif de capteur électrochimique et un module d'acquisition de données et de calcul, à déterminer un effet d'un facteur environnemental à partir de la réponse, à compenser les effets du facteur environnemental par ajustement du signal à partir du dispositif de capteur électrochimique et à délivrer en sortie le signal ajusté.
