Title (EN) LIQUID-SURFACE DETECTION DEVICE
(FR) DISPOSITIF DE DÉTECTION DE SURFACE DE LIQUIDE
(JA) 液面検出装置
Abstract:
(EN) A float (40) floats in a liquid inside a container (11), and thereby moves up and down in accordance with a liquid surface level (LV). A cover (30) is disposed inside the container (11), and accommodates the float in the inside thereof. A detection unit (50) detects the position of the float. The cover (30) has a support part (70) and a wall part (301). The support part (70) allows up-and-down displacement of the float, and restricts displacement of the cover to the outside. The wall part (301) is disposed on the periphery of the support part. An opening (30a) for communicating the outside and the inside of the cover (30) is formed in the wall part (301). The opening area of the opening (30a) is larger than the surface area of the wall part excluding the opening (30a).
(FR) L'invention concerne un flotteur (40) qui flotte dans un liquide à l'intérieur d'un contenant (11) et, de ce fait, monte et descend en fonction d'un niveau de surface de liquide (LV). Un couvercle (30) est disposé à l'intérieur du contenant (11) et loge le flotteur à l'intérieur de ce dernier. Une unité de détection (50) détecte la position du flotteur. Le couvercle (30) a une partie de support (70) et une partie de paroi (301). La partie de support (70) permet un déplacement ascendant et descendant du flotteur, et restreint un déplacement du couvercle vers l'extérieur. La partie de paroi (301) est disposée sur la périphérie de la partie de support. Une ouverture (30a) pour faire communiquer l'extérieur et l'intérieur du couvercle (30) est formée dans la partie de paroi (301). L'aire de l'ouverture (30a) est plus grande que l'aire de la partie de paroi excluant l'ouverture (30a).
(JA) フロート(40)は、容器(11)の内部において液体に浮遊することにより液面レベル(LV)に応じて上下に移動する。カバー(30)は、容器(11)の内部に配置され、フロートを内部に収容する。検出部(50)は、フロートの位置を検出する。カバー(30)は、支持部(70)と壁部(301)とを有する。支持部(70)は、フロートの上下の変位を許容し、カバーの外部への変位を規制する。壁部(301)は、支持部の周囲に配置される。壁部(301)には、カバー(30)の内部と外部とを連通する開口(30a)が形成される。 開口(30a)の開口面積は、開口(30a)を除いた壁部の表面積よりも大きい。
