| titleOfInvention | A leak detection sensor and a composite detection leak detection apparatus including the same |
| abstract | A leak detection sensor and a composite detection type leak detection device including the same are disclosed. Among them, one embodiment of the leak detection sensor is composed of a flexible base pad made of any one selected from PVC, PE, and PP, and the first to fourth conductive wires buried in parallel in the width direction of the base pad, of which the second The 1st and 2nd conductive wires are sensing conductive wires that detect chemical leakage as they come into contact with the leaking chemical. and sensing a change in resistance, wherein sensing grooves in which the first and second conductive lines are partially exposed are provided on one surface and the other surface of the base pad in a direction perpendicular to the longitudinal direction of the base pad or in a diagonal direction, Leak detection sensor further comprising the detection groove and the detection groove of the other surface are alternately arranged with each other; And decomposition voltage detection for detecting the leakage of chemicals by detecting the change in the decomposition voltage (Decomposition Voltage) in the first and second conductive lines of the leak detection sensor when a chemical substance is leaked while being connected to the leak detection sensor wealth; a resistance sensing unit connected to the leak detection sensor and sensing a change in resistance in the first and second conductive lines when a chemical substance is leaked to detect whether a chemical substance is leaked; A leak detection module comprising; a detection switching unit for selectively controlling either one of the decomposition voltage sensing unit and the resistance sensing unit to operate, or for selectively controlling both the decomposition voltage sensing unit and the resistance sensing unit to operate; including, the leak detection module further includes a first connection terminal and a second connection terminal, and when detecting whether a chemical substance is leaked by the decomposition voltage detection unit of the leak detection module, among the four conductive wires of the leak detection sensor, the first and second conductive The line is connected to the first connection terminal, and the third and fourth conductive wires are respectively connected to the second connection terminal, and when detecting whether a chemical is leaked by the resistance sensing unit of the leak detection module, it is connected to the second connection terminal. Connecting the first to fourth conductive wires of the leak detection sensor, and among the first to fourth conductive wires, the third and fourth conductive wires are connected to the second connection terminal through a bar resistance to compare resistance changes. characterized in that |
