Claims (1)

Способ контроля герметичности емкости заключается в создании разности давлений между внутренним давлением емкости и давлением в окружающем ее пространстве с использованием источника для подвода или отсасывания сжатой среды, сообщающегося с внутренним объемом камеры, в которой заключена контролируемая емкость. Выходной сигнал датчика относительного давления запоминается в течение определенного времени в накопителе, выходной сигнал которого в качестве опорного значения давления подается на компаратор. На другой вход компаратора непосредственно подается выходной сигнал датчика относительного давления. Анализ выходных сигналов компаратора позволяет судить о наличии и величине утечки. 4 с., 17 з. п. ф-лы, 6 ил.The method of controlling the tightness of a vessel consists in creating a pressure difference between the internal pressure of the vessel and the pressure in the surrounding space using a source for supplying or suctioning a compressed medium connected to the internal volume of the chamber containing the controlled vessel. The output signal of the relative pressure sensor is stored for a certain time in the accumulator, the output of which is fed to the comparator as a reference pressure value. The output of the relative pressure sensor is fed directly to the other input of the comparator. Analysis of the output signals of the comparator allows you to judge the presence and magnitude of the leak. 4 p., 17 h. item f-ly, 6 ill.
