Title
(EN) GAS SAMPLING AND MANAGEMENT SYSTEM
(FR) SYSTÈME D'ÉCHANTILLONNAGE ET DE GESTION DE GAZ
Abstract
(EN)
A gas monitoring and control system including a gas sampling chamber, sampling inlet and outlet valves, a pump and a controller. Sensors are disposed within the interior chamber that sense characteristics of a gas from a gas source and generate representative signals. The sampling inlet and outlet valves i) allow the gas into the gas sampling chamber while operating in a gas sampling state, and ii) allow ambient air into the gas sampling chamber while operating in a purge state. The pump i) causes the gas to flow through the gas sampling chamber while operating in the gas sampling state or ii) causes ambient air to flow through the gas sampling chamber while operating in the purge state. The controller causes the sampling inlet and outlet valves, and the pump to alternate operating in the gas sampling or purge state to selectively expose the sensors to the gas.

La présente invention concerne un système de surveillance et de commande de gaz comprenant une chambre d'échantillonnage de gaz, des soupapes d'entrée et de sortie d'échantillonnage, une pompe et un dispositif de commande. Des capteurs sont disposés à l'intérieur de la chambre intérieure, lesquels détectent des caractéristiques d'un gaz provenant d'une source de gaz et génèrent des signaux représentatifs. Les soupapes d'entrée et de sortie d'échantillonnage i) permettent l'entrée du gaz dans la chambre d'échantillonnage de gaz lors d'un fonctionnement dans un état d'échantillonnage de gaz, et ii) permettent l'entrée d'air ambiant dans la chambre d'échantillonnage de gaz lors d'un fonctionnant dans un état de purge. La pompe i) amène le gaz à s'écouler à travers la chambre d'échantillonnage de gaz lors d'un fonctionnement dans l'état d'échantillonnage de gaz ou ii) amène l'air ambiant à s'écouler à travers la chambre d'échantillonnage de gaz lors d'un fonctionnement dans l'état de purge. Le dispositif de commande amène les soupapes d'entrée et de sortie d'échantillonnage et la pompe à alterner le fonctionnement dans l'état d'échantillonnage de gaz ou de purge pour exposer sélectivement les capteurs au gaz.
