Liquid leakage detector, liquid transport device and liquid leakage detection method

摘要

PROBLEM TO BE SOLVED: To accurately detect liquid leakage by preventing generation of erroneous detection of the liquid leakage.;SOLUTION: A liquid leakage detector includes: a first liquid detection part 1A fixed on a liquid leakage anxiety position 5 of a liquid pipeline to detect liquid leaked from the liquid leakage anxiety position 5; a liquid impervious member 3 for covering the liquid leakage anxiety position 5 and the first liquid detection part 1A so as to intercept the liquid leakage anxiety position 5 and the first liquid detection part 1A from the outside air; and a control part for determining whether liquid leakage is generated on the liquid leakage anxiety position 5 or not based on a signal from the first liquid detection part 1A.;COPYRIGHT: (C)2012,JPO&INPIT
