专利汇可以提供Moisture leak detector专利检索，专利查询，专利分析的服务。并且A portable moisture leak detector comprising a galvanic cell disposed in an elongated tubular member through which the air to be sampled is drawn. The galvanic cell comprises a pair of dissimilar metal electrodes separated by a deliquescent electrolytic element. Changes in the humidity change the electric output of the galvanic cell. A sudden increase in the output of the cell indicates the presence of a leak enabling it to be located.，下面是Moisture leak detector专利的具体信息内容。

权利要求

1. A mositure leak detector comprising; a. an elongated tubular member having an inlet for receiving an air sample, an outlet and an interconnecting passageway; b. a galvanic cell sensitive to humidity disposed within said passageway, said cell having a pair of electrodes separated by a deliquescent electrolytic element, one of said electrodes and said electrolytic element being permeable to said air; c. means drawing said air through said inlet and said passageway to contact said electrolytic element; and d. variable voltage supply means for applying an external voltage to offset the potential of said galvanic cell under the ambient atomospheric condition such that the net output of said galvanic cell under the ambient condition is substantially zero, and means for detecting an increase in output of said galvanic cell greater than a predetermined value.

2. A moisture leak detector comprising; a. an elongated tubular member having an inlet for receiving an air sample, an outlet and an interconnecting passageway; b. a galvanic cell sensitive to Humidity disposed within said passageway, said cell having a pair of electrodes separated by an electrolytic element comprising a sheet of porous cellulose acetate treated with a deliquescent salt, one of said electrodes and said electrolytic element being permeable to said air; c. means drawing said air through said inlet and said passageway to contact said electrolytic element; and d. means for detecting a change in electrical output of said galvanic cell to indicate the presence of a leak.

3. The apparatus of claim 2 wherein said deliquescent salt is ZnC12.

4. The apparatus of claim 2 wherein said permeable electrode comprises a metallic wire cloth.

5. The apparatus of claim 4 wherein said electrodes comprise an anode of stainless steel wire cloth and a cathode of gold.
