Title:
CONDUCTIVE LIQUID LEAK DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/143176
Kind Code:
A1
Abstract:
The present invention provides a conductive liquid detection device wherein: multiple pairs of primary and secondary electrodes are formed on the front surface and the rear surface of a base layer in the longitudinal direction; the front surface and the rear surface of the base layer are coated with an insulating material, and then sensing holes are formed through the center regions of the primary and secondary electrodes to manufacture a sensor film; a pair of double-sided adhesive tape strips having a predetermined length and thickness are bonded to the bottom surface of the sensor film while the sensing holes formed along the centerline in the longitudinal direction are interposed between the tape strips and the tape strips are spaced a predetermined distance apart from each other in the longitudinal direction of the sensor film; a PET film having a shape corresponding to the sensor film is bonded to the other surface of each of the double-sided adhesive tape strips, and a bottom adhesive tape is bonded to the bottom surface of the PET film, whereby a discharge port through which a liquid to be detected, having introduced through the sensing holes, flows out is formed through the space between the double-sided adhesive tape strips bonded to the bottom surface of the sensor film while being spaced the predetermined distance apart from each other.
