Abstract

PURPOSE: To detect the leakage immediately by a device wherein a pair of conductive paths are formed along a conduit and change in resistance is detected upon the leakage of liquid into the space between the conductive paths.
CONSTITUTION: Voltage is always applied between conductive wires 6 and 7 from a leakage detector 10. When liquid within a conduit 2 is permeated into a heat insulator 3 upon leakage from the conduit 2, a part of the leaked liquid transudes beneath the conduit 2 by its weight or permeating force and enters into a space between the conductive wires 6 and 7. Therefore, electrical resistance between the conductive wires 6 and 7 is reduced due to the presence of the leaked liquid and there is produced current passing between the conductive wires 6 and 7. The leakage detector 10 detects the produced current and displays its value on a recorder 11. Also, an alarm 12 is operated to notice the leakage from the conduit 2.
