Abstract
"SISTEMA DE SENSORIAMENTO INDUTIVO PARA IDENTIFICAR OU DETECTAR UM OBJETO CONDUTIVO OU UM OBJETO CODIFICADO DE MANEIRA CONDUTIVA". Um sistema de sensoriamento indutivo compreende genericamente um indutor sensor, um indutor sensor de referência, um oscilador, uma malha de controle de realimentação e um comparador. O oscilador pode ser conectado a ambos, ao indutor sensor e ao indutor sensor de referência. Quando o oscilador está conectado ao indutor sensor de referência a malha de controle de realimentação estabelece um nível de referência fixo. Quando o indutor sensor está conectado ao oscilador o comparador compara o estado do indutor sensor contra um limiar que é derivado do nível de referência fixo para determinar a mudança em indutância do indutor sensor.
