Abstract

"APARELHO DE MEDIçãO DE VELOCIDADE PARA UTILIZAçãO NA MEDIçãO DE VELOCIDADE DE UM OBJETO QUE SE MOVE". Um transdutor de ultra-som é acoplado a um transmissor que tem uma fonte de sinal ultra-som. Um transdutor de ultra-som receptor é acoplado a um pré-amplificador e misturador. O misturador é ainda acoplado a um demodulador e filtro que por sua vez é acoplado a um amplificador e um comparador. A saída do comparador é acoplada a um controlador que realiza detecção de borda do sinal de saída do comparador. O transmissor produz energia de ultra-som que é refletida a partir de um objeto para o transdutor receptor. O deslocamento em freq³ência entre a energia de ultra-som transmitida e a energia de ultra-som refletida é utilizado para determinar a velocidade do objeto empregando efeito Doppler. Detecção de freq³ência é aprimorada misturando os sinais de ultra-som transmitidos e refletidos para fomecer um sinal de freq³ência de batimento.
