Abstract

Il trasduttore RAD comprende un sensore delle grandezze di misura, una sezione d'alimentazione, una sezione di clock e di temporizzazione e una circuiteria di acquisizione della misura e della sua conversione in frequenza per la trasmissione. Tale circuiteria di acquisizione comprende un microcontrollore, una memoria per i parametri di compensazione in fase di taratura, un convertitore A/D per convertire la misura analogica, fornita dal sensore principale, in forma digitale idonea ad essere elaborata dal microcontrollore, un sensore di temperatura che converte il valore di temperatura in un valore di tensione, un convertitore A/D per convertire la misura analogica data dal sensore di temperatura in forma digitale atta ad essere elaborata dal microcontrollore, e mezzi generatori di frequenza per generare il segnale da trasmettere sulla linea attraverso la sezione d'alimentazione.
