(FR) ENSEMBLE CAPTEUR COMPRENANT UN CAPTEUR DE PRESSION ET UN CAPTEUR DE GAZ THERMIQUE
Abstract
(DE)
Die Erfindung bezieht sich auf eine Sensoranordnung (100), mit einem barometrischen Drucksensor (10) und einem thermischen Gassensor (20), wobei der thermische Gassensor (20) derart auf dem barometrischen Drucksensor (10) oder neben dem barometrischen Drucksensor (1-0) angeordnet ist, dass eine für Gase durchlässige Messstruktur (22) des thermischen Gassensors (20) vor einer Gas-Einlassöffnung des barometrischen Drucksensors (10) oder vor einer druckempfindlichen Oberfläche des barometrischen Drucksensors (10) angeordnet ist.
(EN)
The invention relates to a sensor assembly (100) comprising a barometric pressure sensor (10) and a thermal gas sensor (20), the thermal gas sensor (20) being situated on the barometric pressure sensor (10) or next to the barometric pressure sensor (10), such that a gas-permeable measuring structure (22) of the thermal gas sensor (20) is situated in front of a gas inlet opening of the barometric pressure sensor (10), or in front of a pressure-sensitive surface of the barometric pressure sensor (10).
(FR)
L'invention concerne un ensemble capteur (100) comprenant un capteur de pression barométrique (10) et un capteur de gaz thermique (20), le capteur de gaz thermique (20) étant disposé sur le capteur de pression barométrique (10) ou à côté du capteur de pression barométrique (10) de sorte qu’une structure de mesure (22), perméable aux gaz, du détecteur de gaz thermique (20) est disposée en amont d'une ouverture d'entrée de gaz du capteur de pression barométrique (10) ou en amont d'une surface sensible à la pression du capteur de pression barométrique (10).
