Abstract

La presente invención se refiere a brazo cilíndrico mejorado para un transductor de fuerza, del tipo que genera una señal de salida variable en proporción a los cambios en la magnitud de una fuerza aplicada al mismo, y del tipo que comprende una carcasa con un conjunto de brazo montado en voladizo en la carcasa, el cual incluye una parte de brazo codificada, y por lo menos, un extensimetro unido a la parte de brazo codificada, que funciona para generar una señal de salida, proporcional al esfuerzo producido en el brazo, por una fuerza aplicada al conjunto de brazo, caracterizado porque comprende: una pieza simple prácticamente cilíndrica, con un extremo anclado a la carcasa y el otro extremo libre; una ranura prácticamente en forma de L, formada en el extremo cilíndrico para definir una parte de palanca y la parte de brazo; un primer transmisor de fuerza unido a la parte de palanca; y un segundo transmisor de fuerza unido a la parte de brazo.
