Abstract

Un transmisor (10) montado en el campo, para su uso en un circuito de control (15a/16b) del proceso, de dos alambres, incluye un sensor (12), un sistema de circuitos (18) de evaluacion y un suministro de potencia (20). El sensor (12) detecta una variable del proceso de un proceso el cual se transmite sobre el circuito (16a/16b) de control, por el sistema de circuitos (18) de evaluacion. El suministro de potencia (20) es impulsado por una corriente que fluye a través del circuito (16a/16b) de control e impulsa este sistema de circuitos (18) de evaluacion. El suministro de potencia (29) incluye un elemento inductivo (70) acoplado al sistema de circuitos (18) de evaluacion y un interruptor (64), el cual acopla selectivamente el elemento inductivo (70) al circuito (16a/16b) de control.
