Abstract

PURPOSE: To detect the areas of leak even though the conductive material leaks out at several areas, by securing a parallel connection between each leak detector and leak detection impedance.
CONSTITUTION: In case a leak is detected at Xi of the leak detector 2, the potential based on the Zi of the leak detection impedance 6 is produced at the input terminal of the signal processor 4. This potential is compared with the value which is stored previously in the processor 4. The area of leak is decided when a coincidence is obtained through the above comparison to be displayed by the display device 5. In case the leak occurs at several areas, the potential obtained by the parallel sum of several leak detection impedance 6 of the areas of leak is produced at the input terminal of the processor 4. This potential is turned into the numerical value proper to the area of leak. Thus this value is compared with the stored value to decide and then display the areas of leak.
