Abstract
DETECTOR DE FUMAçA DE LUZ DISPERSA. A presente invenção refere-se a um detector de fumaça de luz dispersa contendo uma disposição opto-eletrónica para a medição de sinais de dispersão (SB, SF) com, pelo menos, um ângulo de dispersão para frente e um ângulo de dispersão para trás, e com um sistema eletrónico de avaliação, para a definição de um valor de alarme em função da diferença dos sinais de dispersão (SB, SF). Dos sinais de dispersão (SB, SF), por meio de um processamento prévio (14) são formados os chamados sinais de fumaça (BW, FW), e desses sinais é obtido um valor de medição (S). O valor de medição (S) é formado por uma ligação linear da soma dos sinais de fumaça (BW, FW) com a diferença dos sinais de fumaça (BW, FW), ou pela formação do valor da diferença dos sinais de fumaça (BW, FW). A ligação linear é calculada de acordo com a fórmula ¢k~ 1~ (BW+FW) + k~ 2~ (BW-FW)!, na qual k~ 1~ e k~ 2~ representam duas constantes influenciadas, entre outras, por um fator de aplicação dependente das condições do ambiente no local de instalação previsto do detector.
