Description

ни  На объекте в местах установки датчиков 1 трещин фольгова  пластина 3 рветс , а излучаемые генератором 10 колебани  навод т электродвижущую си- лу в контуре датчика 1. В паузах работы генератора 10 работает приемный блок 6, по частоте прин тых затухающих колебаний приемный блок определ ет тот датчик, который находитс  в месте возникновени  трещины. Блок 7 регистрации фиксирует тот цикл нагружени , в котором произошло возникновение трещины и разрушение датчика. At the object, in the places where the sensors 1 of the cracks are installed, there is a foil plate 3 rvet, and the oscillations emitted by the generator 10 induce electromotive force in the circuit of the sensor 1. In the pauses of the generator 10, the receiving unit 6 operates the sensor that is in place of the crack. The registration unit 7 fixes the loading cycle in which the occurrence of the crack and the destruction of the sensor occurred.
