Abstract

Aparato de alta precisión para medir las variaciones de distancia entre dos puntos de una obra, tales como dos índices fijos anclados respectivamente en dos paredes de una excavación subterránea, constituído por una caña que incluye un tubo y una varilla que pueden deslizarse la una en el otro, arrastrando cada uno de estos elementos uno de los dos índices de comparación, dispuestos el uno frente al otro, caracterizado porque el índice (22) arrastrado por la varilla (20) está montado en ella por medio de un manguito intermedio (21) de compensación de dilatación térmica sujeto a la varilla (20) en un punto alejado de dicho índice (22).
