Abstract
ES UN CONTADOR DE PARTICULAS QUE TRABAJA SEGUN EL PROCEDIMIENTO DE OSCURECIMIENTO Y QUE ESTA PROVISTO DE UNA BARRERA DE LUZ CUYO RAYO LUMINOSO TRASPASA UN CANAL DE MEDICION PARA UN FLUIDO TRANSVERSALMENTE A LA DIRECCION LONGITUDINAL DEL MISMO. CONSTA TAMBIEN DE UN EVALUADOR ELECTRONICO CONECTADO DETRAS DEL RECEPTOR DE LA BARRERA DE LUZ. LA SUPERFICIE DE SALIDA DE LA BARRERA DE LUZ ESTA FORMADA POR LA SUPERFICIE TERMINAL DE UN HILO DE ALUMBRADO (17) Y LA SUPERFICIE DE ENTRADA DE LUZ ESTA FORMADA POR LA SUPERFICIE TERMINAL DE UN HILO RECEPTOR (19). LA SUPERFICIE TERMINAL DEL HILO DE ALUMBRADO (17) SE ENCUENTRA EN UNA PRIMERA SUPERFICIE LIMITADORA DEL CANAL DE MEDICION (12) Y LA SUPERFICIE TERMINAL DEL HILO RECEPTOR (19) ES CONCENTRICA A ESTA Y SE ENCUENTRA EN UNA SEGUNDA SUPERFICIE LIMITADORA DEL CANAL (12), PARALELA A LA PRIMERA.
