Abstract

SENSOR DE IV, ESPECIALMENTE SENSOR DE CO~ 2~. A presente invenção refere-se a um sensor de IV (1), especialmente um sensor de CO~ 2~, com uma disposição de filtro (6), atrás da qual acha-se disposta uma disposição de detector (7), e um dispositivo de avaliação (8) que se acha conectado com a disposição de detector (7), sendo que a disposição de filtro (6) apresenta um primeiro filtro (9) e um segundo filtro (10) que são configurados como filtros de banda passante e que apresentam respectivamente uma passagem e dos quais o primeiro filtro (9) deixa passar uma banda de IV predeterminada e o segundo filtro (10) não deixa, e a disposição de detector apresenta dois detectores (14,15), dos quais cada um está combinado a um filtro (9, 10). Pretende-se simplificar a aplicação de um sensor de IV desse tipo. Para tanto, é previsto que a banda passante de um filtro (10) esteja disposta dentro da banda passante do outro filtro (9) e o dispositivo de avaliação (8) tira uma diferença dos sinais (S1, S2) dos detectores (14,15) e a adapta ao sinal (S1) de um detector (14). - Novo quadro reivindicatório (total 10 reivindicações) para processamento na Fase Nacional Brasileira.
