Abstract

Se describe un sensor de detecci?n ?ptico que detecta la presencia o ausencia de un producto dentro de un medio de suministro de fluidos. Un emisor dirige radiaci?n dentro del medio de suministro de fluidos. Cada uno de una pluralidad de detectores detecta luz dentro de una pluralidad de escalas de longitudes de onda asociada transmitida a trav?s del medio de suministro de fluidos. La salida de cada detector se asocia adem?s con por lo menos un umbral de salida de producto. Un controlador puede combinar adem?s las salidas de detector, tal como mediante multiplicaci?n, suma u otra operaci?n matem?tica, para producir medidas adicionales de presencia o ausencia de producto. Cada salida en combinaci?n tambi?n es asociada con por lo menos un umbral de salida de producto. El controlador compara la salida de cada detector con los umbrales de salida de producto asociados y compara cada salida en combinaci?n con los umbrales de salida de producto asociados para determinar presencia o ausencia de producto dentro del medio de suministro de fluidos. El sensor es capaz de determinar la presencia o ausencia de una variedad de productos que tengan diferente color, transparencia o turbidez.
