METHOD TESTING CLOSED VESSELS FOR TIGHTNESS, TESTING CHAMBER, TESTING FACILITY AND TESTING PLANT FOR REALIZATION OF METHOD Russian patent published in 2003 - IPC

FIELD: means testing closed vessels for tightness. SUBSTANCE: invention is meant for increase of quality of tightness test of closed vessels, especially vessels partially filled with fluid filling agent, specifically, low-viscous filling agent and is tailored for production lines. Under effect of applied pressure difference on walls of closed vessel fluid filling agents bleeds outside through leak in wall of vessel which is established by measurement of impedance. Impedance between at least one pair of impedance measuring electrodes changes due to bleeding of fluid filling agent through wall of vessel. Measurement of impedance makes it feasible to detect change of this impedance caused by bleeding of fluid filling agent. EFFECT: increased quality of tightness test. 26 cl, 6 dwg
