Abstract

Unità di misura e conversione in cui un convertitore analogico/digitale (9) riceve in ingresso il segnale V(t) generato da un sensore (5) e produce in uscita una parola (D) di otto bit. La parola (D) viene impegnata per indirizzare una memoria EPROM (M) formata da 256 moduli di memoria in modo tale che ad ogni valore della parola (D) viene associato un rispettivo modulo di memoria (MO, M1, M2 .... M255). Ciascun modulo di memoria (MO, M1, M2 .... M255) contiene le informazioni digitali codificate per attivare un dispositivo visualizzatore (17) che visualizza un numero che esprime il valore, espresso in una unità di misura prefissata, della grandezza (T) misurato dal sensore (5).Unit of measurement and conversion in which an analog / digital converter (9) receives as input the signal V (t) generated by a sensor (5) and outputs an eight-bit word (D). The word (D) is used to address an EPROM memory (M) formed by 256 memory modules in such a way that each value of the word (D) is associated with a respective memory module (MO, M1, M2 .... M255). Each memory module (MO, M1, M2 .... M255) contains the digital information encoded to activate a display device (17) which displays a number that expresses the value, expressed in a predetermined unit of measurement, of the quantity (T ) measured by the sensor (5).
