Abstract:
(EN) A liquid level detection device that detects the liquid level of a liquid that is in a container. The liquid level detection device comprises a heater that heats the container, a plurality of temperature sensors that are provided at different heights on the container and detect the surface temperature of the container, and a control device that, on the basis of the surface temperature of the container as detected by the plurality of temperature sensors when the heater has been made to heat, detects the liquid level of the liquid that is in the container.
(FR) L'invention concerne un dispositif de détection de niveau de liquide qui détecte le niveau de liquide d'un liquide qui se trouve dans un récipient. Le dispositif de détection de niveau de liquide comprend un dispositif de chauffage qui chauffe le récipient, une pluralité de capteurs de température situés à différentes hauteurs sur le récipient et qui détectent la température de surface du récipient, et un dispositif de commande qui, en fonction de la température de surface du récipient telle que détectée par la pluralité de capteurs de température lorsque le dispositif de chauffage a été amené à chauffer, détecte le niveau de liquide du liquide qui se trouve dans le récipient.
(JA) 容器内の液体の液面を検知する液面検知装置であって、容器を加熱するヒータと、容器の異なる高さに設けられ、容器の表面温度を検知する複数の温度センサと、ヒータを加熱させた際に複数の温度センサで検知された容器の表面温度に基づき、容器内の液体の液面を検知する制御装置とを備える。
