Abstract

Perfeccionamientos en instalaciones de medida analógica de una magnitud, comprendiendo un circuito eléctrico de medición situado a distancia de una fuente de energía eléctrica que lo alimenta y de un aparato indicador que permite exponer el resultado de la medición, caracterizados porque el indicador se constituye por un aparato de medición de corriente que se acopla en serie en un primer conductor que conecta un primer borne de la fuente al circuito de medición alejado, disponiéndose un segundo conductor de retorno, que conecta el circuito al otro borne de la fuente, siendo el primer y el segundo conductores los dos únicos conductores que unen el circuito a la fuente y al indicador de medición, realizándose la alimentación de energía eléctrica del circuito por dichos conductores y a través del indicador, y comprendiendo el circuito de medición, conectado a una de sus entradas unida a uno de dichos conductores, una fuente de corriente gobernada que produce una corriente variable en funciónde la magnitud medida.
