Since the leakage signals have some characteristics such as low amplitude and wide dynamic range,it is difficult to catch these signals in the real industrial applications.In this paper, a leakage signal acquisition system,which has some unique characteristics such as low noise, low power consumption and easy to be adjusted according to the practical settings,is analyzed and designed.Based on the SCM,this system is capable for signal acquisition and data commu-nication with DSP.It could satisfy the requirements of leak detection and data acquisition in out-door long-distance operation mode.
