Abstract

"SENSOR DE FLUXO VOLUMéRICO EM TEMPO REAL". Trata-se de um sensor para medir não intrusivamente a taxa de fluxo volumérico de materiais, tal como algodão, em uma corrente de ar confinado é descrito, O sensor é montado em um conduíte através do qual o material carreado pelo ar, tal como algodão, flui. O sensor tem uma unidade emissora tendo um série de fontes de luz, tal como um LED, que emite feixes de luz normais ao eixo longitudinal do conduíte. O sensor de fluxo também tem uma unidade detectora que detecta os feixes de luz provenientes das fontes de luz. Os feixes de luz são detectados por circuitos de luz para freq³ência que geram um sinal indicativo da luz sentida. Os feixes de luz são detectados por circuitos de luz para freq³ência que geram um sinal indicativo da luz sentida. Os feixes de luz são atenuados dependendo da quantidade de material que passa através do conduíte. O sinal gerado é enviado para um circuito contador. As saídas do contador são acoplados em um circuito processador que calcula a quantidade de material que flui através do feixe de luz como uma função do sinal de freq³ência e um sinal de freq³ência de linha base indicativo do nível de luz detectado quando nenhum meterial está fluindo através do feixe de luz.
