Title
(EN) GAS SENSOR
(FR) CAPTEUR DE GAZ
(JA) ガスセンサ
Abstract
(EN)
A gas sensor (1) according to the present invention is provided with: a sensor element (2) that has a detection part (21) which is exposed to a gas (G) to be detected and an atmosphere introduction part (361) into which the atmosphere (A) is introduced; and an atmosphere cover (46) in which the atmosphere (A) to be introduced into the sensor element (2) is taken via a vent hole (461). An atmosphere path (460) within the atmosphere cover (46), said atmosphere path (460) being positioned between the vent hole (461) and the atmosphere introduction part (361), is provided with a two-layer atmosphere filter (5) which is composed of a first filter part that has a function of repelling the water in the atmosphere (A) and a second filter part that has a function of adsorbing a poisoning substance in the atmosphere (A).
(FR)
La présente invention concerne un capteur de gaz (1) qui est pourvu : d'un élément de capteur (2) qui comporte une partie de détection (21) qui est exposée à un gaz (G) à détecter et une partie d'introduction d'atmosphère (361) dans laquelle est introduite l'atmosphère (A) ; et d'un couvercle d'atmosphère (46) dans lequel l'atmosphère (A) à introduire dans l'élément de capteur (2) est prise par le biais d'un trou d'évent (461). Un trajet d'atmosphère (460) à l'intérieur du couvercle d'atmosphère (46), ledit trajet d'atmosphère (460) étant positionné entre le trou d'évent (461) et la partie d'introduction d'atmosphère (361), est pourvu d'un filtre d'atmosphère à deux couches (5) qui est composé d'une première partie de filtre qui a une fonction de répulsion de l'eau dans l'atmosphère (A), et d'une seconde partie de filtre qui a une fonction d'adsorption d'une substance d'empoisonnement dans l'atmosphère (A).
(JA)
ガスセンサ(1)は、検出対象ガス(G)に晒される検知部(21)及び大気(A)が導入される大気導入部(361)を有するセンサ素子(2)と、センサ素子(2)に導入される大気(A)が通気口(461)を介して取り込まれる大気カバー(46)とを備える。大気カバー(46)内における、通気口(461)と大気導入部(361)との間の大気経路(460)には、大気(A)中の水を撥水する機能を有する第1フィルタ部と、大気(A)中の被毒物質を吸着する機能を有する第2フィルタ部とによる二層大気フィルタ(5)が設けられている。
