FIRE EXTINGUISHING GAS LEAKAGE DETECTION SENSOR, MANUFACTURING METHOD THEREOF, AND LEAKAGE GAS DETECTION METHOD USING DETECTION SENSOR

摘要

The present invention relates to a fire extinguishing gas leakage detection sensor and a manufacturing method thereof. According to the present invention, the fire extinguishing gas leakage detection sensor comprises: a substrate; an electrode pair formed on the substrate, to which power is applied; a conductive film which is applied to an upper surface of the substrate and the electrode pair, and performs a catalytic action to promote a sensing reaction to gas to be sensed; and a gas sensing film which is coated on an upper portion of the conductive film, and receives power from the electrode pair. The gas sensing film comprises any one selected from a semiconductor metal oxide group including tin oxide (SnO_2) and a zirconium compound (ZrOCl_2) or an alloy thereof. According to the present invention, a gas leakage is sensed in advance by a gas sensor for detecting a fluorine ion (F-) or hydrogen fluoride (HF) to prevent malfunction of a fire extinguishing facility and a fatal accident to maintain a complete fire protection system in an emergency.;COPYRIGHT KIPO 2017
