Abstract
REGULADOR DE LA VELOCIDAD DEL AIRE EN DOSIMETROS. CONSISTE EN HACER PASAR POR EL FILTRO (2) UNA CORRIENTE DE AIRE A VELOCIDAD CONTROLADA PARA EVITAR ERRORES EN LA MEDICION DE LAS PARTICULAS RETENIDAS. ESTE CONTROL SE REALIZA MEDIANTE DOS DEPOSITOS AMORTIGUADORES (3, 5) DE LAS PULSACIONES PRODUCIDAS POR LA ASPIRACION Y LA IMPULSION DE UNA BOMBA (4) MOVIDA POR UN MOTOR ELECTRICO (18), QUE ES CONTROLADO POR UN CIRCUITO ELECTRONICO (17,20), QUE RECIBE ORDENES DEL CONMUTADOR DE PRESION (14). AL VARIAR LA PRESION EN LOS FILTROS (13), EL CONMUTADOR (14) LO COMUNICA AL MOTOR (18), MODIFICANDO EL BOMBEO CONVENIENTEMENTE. EXISTEN VARIANTES DE CONSTRUCCION.
