Abstract

Distanciómetro con un sistema electrónico de evaluación y un dispositivo de sensor, detectándose dos vástagos de émbolo que se mueven uno dentro de otro al mismo tiempo y de forma independiente el uno del otro, y que presenta al menos dos sondas de acoplamiento para la aportación de señales de emisión a la respectiva estructura de líneas con respectivamente un cuerpo de reflexión, siendo los cuerpos de reflexión la cara frontal del vástago de embolo de los respectivos cilindros y guiándose el vástago de émbolo interior en un tubo de guía y configurándose, para la detección del vástago de émbolo exterior, un sistema coaxial en el que el tubo de guía del vástago de émbolo interior sirve de conductor interior del sistema coaxial para la detección del vástago de émbolo exterior.
