Abstract

EN UN METODO PARA DETECTAR PARTICULAS EN UN FLUJO DE GAS, UNA SONDA (8) ESTA CARGADA TRIBOELECTRICAMENTE POR PARTICULAS (10) EN EL FLUJO Y LAS CANTIDADES DE CARGAS ELECTRICAS TRANSFERIDAS A LA SONDA SON EVALUADAS PARA PROPORCIONAR UNA INDICACION DEL FLUJO DE LA PARTICULA EN EL FLUJO DE GAS. PARA REDUCIR EL EFECTO DE VARIACIONES EN " VARIABLES RELACIONADAS CON EL FLUJO DE GAS" DISTINTAS A AQUELLAS RELATIVAS AL FLUJO DE LA PARTICULA, UN COMPONENTE DE ALTERNANCIA EN LA SEÑAL OCASIONADA POR LA CARGA TRIBOELECTRICA DE LA SONDA ES SUPERVISADO.
