Title (EN) FLUID RESERVOIR WITH FLUID PROPERTY AND LEVEL DETECTION
(FR) RÉSERVOIR DE FLUIDE AYANT UNE PROPRIÉTÉ DE FLUIDE ET UNE FONCTION DE DÉTECTION DE NIVEAU
Abstract:
(EN) A fluid reservoir (101) includes a number of electrode pairs disposed within the fluid reservoir. Each of the electrode pairs includes a number of sensing electrodes (103), and a number of electrical traces (105) wherein the sensing electrodes are coupled to a respective one of the electrical traces. The fluid reservoir also includes a common electrode (104) electrically coupled to a voltage source (106). A number of properties of a fluid (110) within the fluid reservoir are detected by applying a voltage between the sensing electrodes in an electrode pair, and a level of the fluid within the fluid reservoir is detected by applying a voltage between the electrodes and the common electrode. A multiplexer (102) may be used to selectively couple the sensing electrodes (103) to a processing device (108). The fluid reservoir may be a printing fluid container.
(FR) L'invention concerne un réservoir de fluide (101) comprenant un certain nombre de paires d'électrodes disposées à l'intérieur du réservoir de fluide. Chacune des paires d'électrodes comprend un certain nombre d'électrodes de détection (103) et un certain nombre de traces électriques (105), les électrodes de détection étant couplées à une trace électrique respective parmi les traces électriques. Le réservoir de fluide comprend également une électrode commune (104) couplée électriquement à une source de tension (106). Un certain nombre de propriétés d'un fluide (110) à l'intérieur du réservoir de fluide sont détectées par application d'une tension entre les électrodes de détection dans une paire d'électrodes et un niveau du fluide à l'intérieur du réservoir de fluide est détecté par application d'une tension entre les électrodes et l'électrode commune. Un multiplexeur (102) peut être utilisé pour coupler sélectivement les électrodes de détection (103) à un dispositif de traitement (108). Le réservoir de fluide peut être un récipient de fluide d'impression.
