Abstract

DISPOSICIONES PARA EL CONTROL DE LA TEMPERATURA Y VELOCIDAD DE ENFRIAMIENTO Y CALENTAMIENTO DE UN ELECTRODO DE SOLERA. LOS ELECTRODOS DE SOLERA (5) CONTIENEN EN DIVERSOS PUNTOS ESPACIADOS TERMOSONDAS CONECTADAS EN (11) CUYAS SEÑALES SON PASADAS A UN ELEMENTO CONTROLADOR (13) QUE ACTUA SOBRE UN APARATO REGULADOR (23) QUE MANDA AL VENTILADOR (15) Y LA APERTURA DE LA VALVULA (17) SEGUN LOS VALORES SUMINISTRADOS POR EL PROGRAMADOR (25). EL CONTROL PUEDE SER TAMBIEN EFECTUADO MANUALMENTE.
