发明名称 Liquid leakage detection apparatus including wheatstone bridge
摘要 Liquid leakage detection apparatus is provided comprising: (a) a long detecting component wherein there are the following components bundled together: (i) a first conductor having a leading end and a trailing end, the first conductor covered by insulation, (ii) a second bare conductor having a leading end and a trailing end, the second conductor positioned parallel to the first conductor, the trailing end of the second conductor being connected with the trailing end of the first conductor, and (iii) a third conductor covered by a porous insulation and positioned parallel to the second conductor, (b) the leading end of the first conductor and the leading end of the second conductor being connected by the detecting means which detects and indicates a potential difference between the first and second conductors; (c) the leading ends of the first and second conductors also being connected, respectively, to one of the electrodes of a power supply, each through respective, known resistances; and (d) the third conductor being connected to the other electrode of the power supply such that a Wheatstone Bridge circuit is formed when the second conductor and third conductor are short circuited by a leaking liquid.
