Abstract

Un circuito y un método para utilizar multiples sensores resistivos y en particular sensores de temperatura resistivos mientras se minimiza la cantidadde conductores necesarios para medir los multiples sensores. Los multiples sensores están conectados en serie y la tension es medida en cada nodo en lacondicion serie de sensores. Un dispositivo de conmutacion después abre para desconectar uno de los sensores del suministro de tension permitiendo efectuaruna medicion de la resistencia del conductor entre los sensores de temperatura y un transmisor remoto. Las resistencias medidas son después compensadas con laresistencia de conductor medida para obtener una resistencia compensada con la longitud del conductor para cada uno de losmultiples sensores resistivos.
