| Abstract: | Hitting damage to oil and gas transmission pipelines has already been the major damage factor to pipe leaking. In this paper, the design of amplifier based on AD620 is described. And a design method of the two-order passband filter is provided in detail. The circuit is simulated by Muhisim and is proved to acquire good effect by the experiment of detecting the weak signal from hitting to pipeline. |
