A device for inner defectoscopy of main pipelines comprises a transport module and a measuring module installed in it, this consists of acoustic receiving-emitting system that has piezoelectric transducers and is fixed on transport module. The device has as well connected in series synchronizer, generator of excitation pulses, multi-channel receiving-amplification block, block for primary information processing, block for control, information storage and energy saving. As block for determination of location a GPS module is installed for determination of coordinates of the defect, and for on-line transfer of data obtained. |
