Abstract
A gas detection fuse is provided, comprising a thin strip or sheet of a conductive material, such as a metal, connecting two electrodes for detecting a gas of interest. The metal is selected to be reactive with the gas of interest, and has a relatively large surface area, such that when the gas of interest contacts the metal, the electrical connection between the electrodes is broken (e.g., due to the metal losing physical integrity, or becoming non-conductive, as a result of the reaction with the gas). The gas of interest may be chlorine, and the conducting material may be tin. When the tin is exposed to chlorine the tin becomes oxidized to produce liquid tin tetrachloride, thus breaking the electrical connection.
Claims12
A gas detection fuse, comprising:
- a pair of electrodes;
- and
- a connecting member coupled to the pair of electrodes, the connecting member comprising a tin conducting material in electrical communication with the pair of electrodes, wherein the tin conducting material is reactable with chorine gas to produce liquid tin tetrachloride and thereby break the electrical communication between the pair of electrodes.
