Title (EN) PHYSICAL QUANTITY DETECTION DEVICE
(FR) DISPOSITIF DE DÉTECTION DE QUANTITÉ PHYSIQUE
(JA) 物理量検出装置
Abstract:
(EN) The present invention addresses the problem of obtaining a physical quantity detection device wherein thermal effects to sensors due to miniaturization can be suppressed. A physical quantity detection device 20 according to the present invention has a measuring unit 213 that protrudes toward the path center of a main path 22 from an inner wall of the main path. The physical quantity detection device is provided with: a flow rate sensor 205 that detects the flow rate of a gas 2 to be measured; an intake air temperature sensor 203 that detects temperature; and a pressure sensor 204 that detects pressure and/or a humidity sensor 206 that detects humidity. Respective kinds of sensors are disposed in the protruding direction of the measuring unit 213.
(FR) La présente invention aborde le problème de l’obtention d’un dispositif de détection de quantité physique dans lequel les effets thermiques subis par les capteurs, en raison de la miniaturisation, peuvent être éliminés. Un dispositif de détection de quantité physique 20 selon la présente invention comprend une unité de mesure 213 faisant saillie vers le centre de trajet d’un trajet principal 22 à partir d’une paroi interne du trajet principal. Le dispositif de détection de quantité physique comprend : un capteur de débit 205 qui détecte le débit d’un gaz 2 à mesurer ; un capteur de température d’air d’admission 203 qui détecte la température ; et un capteur de pression 204 qui détecte la pression et/ou un capteur d’humidité 206 qui détecte l’humidité. Des types respectifs de capteurs sont disposés dans la direction de la saillie de l’unité de mesure 213.
(JA) 小型化に起因するセンサへの熱影響を抑制することができる物理量検出装置を得ること。 本発明の物理量検出装置20は、主通路22の内壁から主通路の通路中心に向かって突出する計測部213を有している。そして、被計測気体2の流量を検出する流量センサ205と、温度を検出する吸気温度センサ203と、圧力を検出する圧力センサ204または湿度を検出する湿度センサ206のすくなくともいずれかを備え、各種センサは計測部213の突出方向に沿って配置される。
