Abstract

"MéTODO DE MONITORAMENTO DE PRESSãO EM UM PNEUMáTICO". Um método (650) de calibração de um transponder (200, 604) capaz de medir dados de temperatura (N~ T~) e dados de pressão (N~ P~) num objeto (por exemplo, num pneumático (104)) e transmitir um fluxo de dados (figura 3C) a um leitor/interrogador externo (106, 400). O transponder dispõe de memória (238) para armazenar os dados de medição, calibração (662), número de ID do transponder e outros mais. Uma vez que o transponder combina informações de temperatura e pressão nos dados de "pressão", a relação N~ T~/N~ P~ é um indicador direto somente de pressão, e é também relativamente insensível a variações na potência do transponder. O método de calibração emprega uma câmara de calibração (602) que tem sensores de pressão (614) e de temperatura (612) de referência. O transdutor a ser calibrado é colocado na câmara e exposto (652) a um certo número de temperaturas e pressões predeterminadas (medidas pelos sensores de referência) num certo número de pontos de calibração. Em cada ponto de calibração, uma leitura de temperatura (N~ T~) e uma leitura de pressão (N~ P~), detectadas pelo transponder, são registradas, juntamente com a temperatura e pressão de referência. A partir dessas leituras e das medições de referência, as constantes de calibração (N~ T25~, m~ T~, N~ T~/N~ P700,25~, m~ P~) são calculadas (658).
