The leak detection sensor and leak detection system using it

摘要

A first member and a second member; A sensing line having a projection shape formed on the first member; An outlet-type sensing wire configured in the second member so as to correspond to the sensing wire of the protrusion shape; Comprising the water-expandable material or the spring space configured to accommodate the water-expandable material or the spring in the first member and the second member, The pipe joint defect detection sensor and the leak detection using the same, characterized in that for inserting the water-expandable rubber material or the spring portion in the spring space before inserting the projection-type sensing wire into the outlet-type detection wire It''s about the system.
