Abstract

Il trasduttore remoto indirizzabile comprende un sensore di grandezze da misurare, un circuito di clock, un circuito di indirizzamento/temporizzazione, un alimentatore, un circuito per l'acquisizione delle misure e la loro conversione in frequenza per la trasmissione e una linea per l'alimentazione e l'invio di tale segnale in frequenza. Il sistema d'indirizzamento elettronico prevede l'utilizzo di un programmatore elettronico d'indirizzo da collegare ai due fili di linea del trasduttore da programmare. Il circuito corrispondente presente sul trasduttore stesso consiste in un rivelatore di polarità, un microcontrollore incorporante le funzioni dei circuiti di clock, di indirizzamento e di temporizzazione del trasduttore per provvedere al conteggio del tempo trascorso dall'accensione, alla sua comparazione con l'indirizzo programmato e alla generazione di un segnale per l'attivazione del circuito di acquisizione delle misure e una memoria non volatile per memorizzare l'indirizzo.The addressable remote transducer includes a sensor of quantities to be measured, a clock circuit, an addressing / timing circuit, a power supply, a circuit for the acquisition of the measures and their conversion into frequency for the transmission and a line for the power supply and sending this signal in frequency. The electronic addressing system involves the use of an electronic address programmer to be connected to the two line wires of the transducer to be programmed. The corresponding circuit present on the transducer itself consists of a polarity detector, a microcontroller incorporating the functions of the clock, addressing and timing circuits of the transducer to count the time elapsed since the power is turned on, comparing it with the programmed address. and to the generation of a signal for activating the measurement acquisition circuit and a non-volatile memory to store the address.
