¿Por qué la señal de 4-20 miliamperios en las señales de los instrumentos no es de 0-20 miliamperios?
Reply #22017-05-28
Mientras el conductor permita que la corriente sea cero, es algo difícil de comprender

La señal es demasiado débil y no es estable; si es cero, ¿cómo puede haber conducción de electricidad?

Para separar el punto cero de la señal del punto cero eléctrico.
