(EN) SYSTEM AND METHODS FOR CHARACTERIZING A LIQUID
(FR) SYSTEME ET PROCEDE DE CARACTERISATION D'UN LIQUIDE
Abstract
(EN) A system for characterizing a liquid comprises a sensor for providing an electrical output signal depending on a characteristic of the liquid, and a processing unit for processing the output signal of the sensor to obtain characterizing data of the liquid. The sensor is made as a single sensor/actuator device and can be connected in a plurality of manners to the processing unit. In at least some of these connecting manners the processing unit is adapted to actuate the sensor/actuator device and to process the output signal of the sensor/actuator device to obtain different characterizing data of the liquid.
(FR) L'invention concerne un système de caractérisation d'un liquide comprenant un capteur fournissant un signal de sortie électrique en fonction d'une caractéristique du liquide et une unité de traitement permettant de traiter le signal de sortie du capteur pour obtenir les données de caractérisation du liquide. Le capteur, servant de dispositif de détection/actionnement, est formé en une seul pièce et peut être connecté de diverses façons à l'unité de traitement. Selon au moins certaines variantes, cette unité de traitement est adaptée pour actionner le dispositif de détection/actionnement et pour traiter le signal de sortie du dispositif de détection/actionnement de manière à obtenir différentes données de caractérisation du liquide.
