Abstract

Circuito de puente de medición en técnica de conductor trifilar con al menos una banda extensométrica (1,20) en circuito de puente, que está en conexión, a través de una primera línea de conexión (4,22), con una resistencia complementaria (RE, RE1, RE2, RE3) y con una segunda línea de conexión (16,19) con una fuente de tensión de alimentación (12), donde está prevista una tercera línea de conexión (6,21), que está conectada con un primer circuito amplificador (8) de alta impedancia en la diagonal de medición, caracterizado porque entre la primera línea de conexión (4) y la tercera línea de conexión (6) está previsto un segundo circuito amplificador (9) de alta impedancia con un factor de amplificación v=2, que sirve para la regulación posterior de la tensión de alimentación (UB).
