Title (EN) INK LEVEL CONTROL
(FR) COMMANDE DE NIVEAU D"ENCRE
Abstract:
(EN) An ink level control for a printing press is disclosed having an ultrasonic ink level sensor (30) to receive an echo signal representative of the level of the ink in the ink fountain. A control is provided whereby the ink level is maintained at a desired operating level and conditions of excessively low and high ink levels are also detected by the sensor. An echo loss detection network (110) is provided to warn the operator and inhibit ink feeds. The control is designed to prevent overflow of the ink fountain (12).
(FR) Commande de niveau d"encre d"une presse d"imprimerie ayant un detecteur de niveau d"encre ultrasonique (30) pour recevoir un signal d"echo d"indication du niveau de l"encre dans le distributeur d"encre. Une commande est prevue pour maintenir le niveau d"encre a un niveau de fonctionnement ideal et les niveaux excessivement bas ou eleves de l"encre sont aussi detectes par le detecteur. Un reseau de detection de perte de l"echo (110) avertit l"operateur et ferme les conduits d"alimentation d"encre. La commande est concue pour empecher le debordement du distributeur d"encre (12).
