Title:
液体検出システムおよび液体検出方法
Document Type and Number:
Japanese Patent JP6828704
Kind Code:
B2
Abstract:
This liquid detection system comprises: a magnetic member provided in a detection-target space; a magnetic flux density sensor that measures a magnetic flux density generated by the magnetic member; and a detector that detects the infiltration of a liquid into the detection-target space on the basis of the change amount of the magnetic flux density. The magnetic member comprises: a liquid absorption member that transforms by absorbing a liquid; and magnetic particles that undergo displacement in conjunction with the transformation of the liquid absorption member. The provided liquid detection system thus has a high degree of freedom with respect to the detection-target space.
