Title
(EN) GAS SENSORS
(FR) CAPTEURS DE GAZ
Abstract
(EN)
Gas sensor comprising a catalyst material; a temperature detector configured to measure a change in temperature of the catalyst material; and a plurality of electrodes configured to measure the current and/or resistance of the catalytic material wherein the gas sensor is configured such that the temperature detector provides the calorimetric output and the plurality of electrodes provide the resistive or capacitive output..
(FR)
L'invention concerne un capteur de gaz comprenant un matériau catalyseur; un détecteur de température conçu pour mesurer un changement de température du matériau catalyseur; et une pluralité d'électrodes conçues pour mesurer le courant et/ou la résistance du matériau catalyseur, le capteur de gaz étant conçu de telle sorte que le détecteur de température fournisse la sortie calorimétrique et que la pluralité d'électrodes fournissent la sortie résistive ou capacitive.
