Abstract
DISPOSITIVO DE CONTROL PARA EL CONTROL TEMPORAL DE LA PRESION DE LLENADO AL LLENAR UN UTIL DE PRENSAR CON UNA MASA PASTOSA Y BARROSA, ESPECIALMENTE PARA LA FABRICACION DE IMANES DE OXIDO. A TAL FIN, ESTA PREVISTO UN SENSOR MANOMETRICO (14) QUE REGISTRA LA PRESION EN EL UTIL DE PRENSAR (11) Y QUE CONDUCE UNA SEÑALA DE PRESION CORRESPONDIENTE A UN PRIMER NIVEL DE VALOR UMBRAL (19) Y, A TRAVES DE UN MIEMBRO DIFERENCIAL, A UN SEGUNDO NIVEL DE VALOR UMBRAL (21). LAS SALIDAS DE LOS DOS NIVELES DE VALOR UMBRAL (19, 21) ESTAN CONECTADAS CON UNA PUERTA LOGICA (22) QUE, SI SIMULTANEAMENTE SE EXCEDE UN PRIMER VALOR UMBRAL DEL PRIMER NIVEL DE VALOR UMBRAL (19) Y NO SE ALCANZA UN SEGUNDO VALOR UMBRAL DEL SEGUNDO NIVEL DE VALOR UMBRAL (21), GENERA UNA SEÑAL DE DISPARO PARA UN MIEMBRO TEMPORIZADOR (23) CONECTADO DETRAS.
