Abstract

SENSOR DE PROXIMIDADE SEM FIO PARA DETECTAR A POSIçãO DE UM OBJETO, SISTEMA DE DETECçãO DE PROXIMIDADE SEM FIO E MéTODO PARA DETECTAR SEM FIO A POSIçãO DE UM OBJETO. A presente invenção refere-se a um sensor de proximidade sem f ia e a um sistema de detecção para detectar a posição de um objeto. O sistema inclui um transceptor para prover uma comunicação sem f ia com um sensor passivo de proximidade de onda acústica de superfície (OAS) sem f ia. O sensor de proximidade sem f ia recebe um sinal sem f ia do transceptor, que aciona o dispositivo de OAS e transmite por sua vez um sinal de volta ao transceptor que inclui a informação sobre a posição de um objeto. O sensor de proximidade sem f ia utiliza um ou mais dispositivos de OAS com um elemento de detecção feito de um material magnetostritivo, conjuntamente com um ou mais ímãs e um ou mais alvos que são posicionados em relação a um objeto. O movimento do(s) alvo(s) com relação ao sensor de proximidade produz operativamente uma resposta mecânica devido à mudança no campo magnético do elemento de detecção. O elemento de detecção, por sua vez, intensifica o campo magnético do dispositivo de OAS ao qual é unido, e esta informação é transmitida ao transceptor como informação sobre a posição de um objeto.
