FIELD: construction. ^ SUBSTANCE: method comprises using the pipeline to be tested as a wave guide and mounting emitter in the balk of the electric insulation of the pipeline. The aerial of the emitter is connected with the aerial of the writer through the pipeline. The address emitter comprises rectifier, memory, threshold element, and decoder. The aerial is connected to the input of the rectifier whose output is connected with the bus for power supply to the emitter through the carrier and threshold element. The power supply bus of the decoder is connected with the input of the threshold element. The signal input is connected with the aerial, and signal output is connected with the input of the emitter. ^ EFFECT: enhanced reliability of testing. ^ 3 cl, 3 dwg |
