Abstract

"SENSOR DE UMIDADE E PROCESSO PARA DETECTAçãODE UMIDADE SOBRE SUPERFìCIE DE UM MATERIALTRANSPARENTE E CIRCUITO DE BALANCEAMENTOAUTOMáTICO PARA UM SENSOR DE UMIDADE". Trata-se deum circuito de controle de balanceamento automático (80) parautilização num sensor de umidade que detecta umidade sobre asuperfície de um material transparente. O sensor de umidade incluidetetores (44, 54) para recepção de sinais de emissor (42) que sãoinfluenciados por umidade sobre o material transparente. O sensorde umidade inclui adicionalmente um circuito de pré-desmodulação(60) para atenuação de componentes de sinal indesejáveis no sinalde saída do detetor simultaneamente amplificando oscomponentes de sinal úteis para processamento adicional por ummicrocomputador (65). Um circuito de balanceamento automático(80) é provido para receber o sinal de circuito depré-desmodulação (64) e, fornecer um sinal de balanceamentoautomático (98) para a entrada do circuito de pré-desmodulação. Osinal de balanceamento automático cancela pelo menosparcialmente o sinal de saída do detetor para impedir a ocorrênciade saturação do amplificador de pré-desmodulação quando sãoencontradas amplitudes indesejáveis do sinal de saída do detetor.Ao impedir a saturação dos circuitos do sensor de umidade, ocircuito de balanceamento automático permite ao sensor continuara operar na presença de grandes gotas de umidadesimultaneamente tendo ganho suficiente para detectar pequenasgotículas de umidade.
