APPARATUS FOR MEASURING VIBRATION IN CABLE PIPELINE

摘要

PURPOSE:To exclude the obstruction due to the existence of an output cord, by inserting the output cord and a fluid transmitting hose through the piercing hole in a case. CONSTITUTION:When the displacement wave accompanied by the passage of a vehicle through a cable pipeline is measured by using a plurality of apparatuses each for measuring vibration in the cable pipeline, the output cords 11 of the apparatuses and the fluid transmitting hoses connected to cylinders are collectively inserted into plastic tubes and inserted through the piercing holes 3a of rear apparatuses to connect the apparatuses through a wire. By this method, when a plurality of apparatuses are drawn into the cable pipeline to be measured and used, the obstruction due to the existence of output cords can be excluded.
