Abstract

um medidor de detecção de nível nuclear (30) para medir o nível de produto em um compartimento (32). o medidor inclui uma fonte de radiação nuclear (36) posicionada adjacente ao produto no compartimento e uma câmara (34). um cintilador primário (40) é fornecido na câmara (34), adjacente ao produto no compartimento (32) e de frente para a fonte de radiação nuclear (36). a radiação nuclear proveniente da fonte (36) passa ao longo do compartimento (32) e colide sobre o cintilador primário (40), gerando luz cintilante. uma guia de luz (44) transmite a luz cintilante do cintilador primário (40) para o sistema de circuitos detectores de luz (12). a guia de luz (44) é acoplada ao cintilador primário (40) através de um espaço de ar. a guia de luz (44) produz sinais luminosos de cintilação em resposta à absorção da luz cintilante do cintilador primário (40). o sistema de circuitos detectores de luz (12) coleta os sinais luminosos da guia de luz (44) para fornecer uma representação do nível de produto que absorve radiação no compartimento.
