Abstract

Un transmisor (22) en un circuito de control de proceso (34) incluye un sensor (40) para detectar una variable del proceso. Un convertidor analogico a digital (42, 44) acoplado con el sensor (40) proporciona una variable del proceso digitizada durante los distintos tiempos de muestreo. Una interfaz (54) acopla el transmisor con el circuito de control (34) y si se usa para comunicar la informacion y recibir la energía a través del circuito de control (34). El transmisor (22) incluye un reloj (52) y una memoria (50). Un microprocesador (48) acoplado con el reloj (52) y la memoria (50) almacena las variables del proceso digitizadas y la informacion de reloj en la memoria (50). El almacenamiento es de manera tal que puede determinarse el tiempo de muestreo de una variable de proceso digital almacenada.
