Title (EN) PRINTHEADS WITH SENSOR PLATE IMPEDANCE MEASUREMENT
(FR) TÊTES D'IMPRESSION PRÉSENTANT UNE MESURE DE L'IMPÉDANCE DE PLAQUE DE DÉTECTION
Abstract:
(EN) In an implementation, a printhead includes a nozzle and a fluid channel. A sensor plate is located within the fluid channel. An impedance measurement circuit is coupled to the sensor plate to measure impedance of fluid within the channel during a fluid movement event that moves fluid past the sensor plate.
(FR) Selon un mode de réalisation, une tête d'impression comprend une buse et un canal de liquide. Une plaque de détection est située dans le canal de liquide. Un circuit de mesure d'impédance est couplé à la plaque de détection pour mesurer l'impédance du liquide à l'intérieur du canal au cours d'un événement de déplacement de liquide qui déplace un liquide au-delà de la plaque de détection.
