Abstract
UN DISPOSITIVO DOSIFICADOR PARA SUBSTANCIAS QUE FLUYEN LENTAMENTE, COMO GRANULADO, POLVO Y LIQUIDOS CONSTA DE UN DEPOSITO DE MATERIAL PROVISTO CON UNA INSTALACION DE DESCARGA REGULABLE, Y UNA INSTALACION DE PASAJE (MZ) PARA EL DEPOSITO DE MATERIAL O PARA UN RECORRIDO DE TRANSPORTE DISPUESTO A CONTINUACION DE LA INSTALACION DE DESCARGA. ESTA ADJUDICADO UN CIRCUITO ELECTRONICO PROVISTO CON UN TOTALIZADOR (MP) PARA LA REGULACION Y CONTROL DE LA INSTALACION DE DESCARGA, QUE CUENTA LOS IMPULSOS DE MEDICION DIGITAL DE LA INSTALACION DE PESAJE FORMADOS EN UN INTERVALO DE TIEMPO, LOS COMPARA CON UN VALOR TEORICO (SW) Y, EN CASO DE UNA DESVIACION, FORMA UNA MAGNITUD DE AJUSTE PARA LA INSTALACION DE DESCARGA. PARA PODER MANTENER UNA DOSIFICACION GRAVIMETRICA EN CASO DE PERTURBACIONES EXTERNAS Y/O AL RELLENAR EL DEPOSITO, DEL QUE SE EXTRAE EL MATERIAL, EL CIRCUITO PRESENTA UNA INSTALACION PARA LA FORMACION Y ELABORACION DE UN VALOR DE SOPORTE (SS), LA CUAL ANTES DE UNA UTILIZACION FUNCIONAL DE LA INSTALACION DOSIFICADORA EN UNA OPERACION DE AJUSTE LIBRE DE PERTURBACIONES AMBIENTALES, A UNA O VARIAS VELOCIDADES DE TRANSPORTE DE LA INSTALACION DE DESCARGA, ALMACENA LOS IMPULSOS DE MEDICION DE LA INSTALACION DE PESAJE, LOS CONVIERTE CON LA AYUDA DEL VALOR TEORICO A LA ZONA DE REGULACION, AÑADE LOS VALORES DE APOYO A LOS IMPULSOS DE MEDICION FORMADOS EN LA UTILIZACION FUNCIONAL DURANTE LA APARICION DE IMPULSOS DE MEDICION SOBREELEVADOS O DE VEZ EN CUANDO A TRAVES DE UN GENERADOR DE IMPULSOS DE RELOJ (T). ADEMAS, EL CIRCUITO COMPARA LOS VALORES MIXTOS CON EL VALOR TEORICO Y, EN CASO DE UNA DESVIACION, FORMA LAS MAGNITUDES DE AJUSTE PARA LA INSTALACION DE DESCARGA.
