PURPOSE: An acoustic-emission signal sensor and a wireless drawback diagnosing system using the same are provided to wirelessly diagnose the presence/absence, level, and position of drawbacks of a high-pressure pipe and effectively give said drawbacks to a user. CONSTITUTION: An acoustic-emission signal sensor comprises an AE(Acoustic Emission) sensor, a housing(12), an elastic member, and a signal processing module. For the AE sensor, a first connector is installed on one side and bottom making tight contact with a curved magnetic high-pressure pipe is substantially level. For the housing, an elongated part is formed from bottom, to which at least one magnet is attached, and the AE sensor is held so that the bottom is exposed. A second connector coupled to the first connector is installed on one side of the elongated part. The elastic member is inserted into the elongated part and shows elasticity so that the AE sensor becomes apart from the housing. |
