Abstract

“indicador de detecção de nível nuclear e método para medir o nível de produto em silo” resumo a presente invenção refere-se a um indicador de detecção de nível nuclear para medição do nível de produto em um silo que usa uma pluralidade de cintiladores (14/16) dispostos em série. uma fonte de radiação nuclear (s) é posicionada adjacente ao silo, e os cintiladores, que podem ser feixes de uma ou mais fibras cintilantes ou cristais cintilantes, são posicionados em série adjacentes ao silo em oposição à fonte de radiação nuclear, de modo que a radiação nuclear que passa pelo silo colide com os feixes. guias de luz (18) transportam fótons emitidos pelos cintiladores - os quais são indicativos de radiação que passa através do silo - para um tubo fotomultiplicador comum (12). o tubo é conectado a componentes eletrônicos (10) que convertem a contagem de fótons do pmt em uma medida do nível de produto de absorção de radiações no silo. 1/1
