The paper introduces the principle, method and related test for detecting the advancing ram' s movement in hydraulic supports. The results show that it is totally feasible to detect the advancing ram's movement by ultra sonic with the accuracy of 0.1% ～0.9%. It is easy to install with high reliability, compared with the difference transformer sensors. It provides technical condition for developing industrial ultra sonic sensor used for defecting advancing ram's movement in the condition of underground. They will be widely used in future.
