Title (EN) CAPACITIVE CONTINUOUS FLUID LEVEL SENSOR
(FR) CAPTEUR DE NIVEAU CAPACITIF DE FLUIDE CONTINU
Abstract: front page image
(EN)A fluid level sensor includes fluid sensing electrodes, reference electrodes, and a controller. The reference electrodes compensate for temperature fluctuations about the fluid electrodes. The controller determines fluid level based on the response of the fluid electrodes to the presence of the fluid in proximity thereto.
(FR)Un capteur de niveau de fluide comprend des électrodes de détection de fluide, des électrodes de référence et un contrôleur. Les électrodes de référence compensent les fluctuations de température autour des électrodes de fluide. Le contrôleur détermine le niveau de fluide sur la base de la réponse des électrodes de fluide à la présence du fluide à proximité de celle-ci.
