Abstract
Device for detecting combustible gases. This device is constituted by an electrically resistant element and a negative temperature coefficient. The element carries two electrodes, establishing a current between them through the element when it is hot. One of the electrodes is also a resistance that heats the element and maintains it at a constant temperature in order to establish a weak current. The element carries a catalyst of gases that is at the same temperature as the element, having calculated this temperature so that it is able to activate the catalyst and produce the catalysis of the gases. When catalysis is produced, the temperature of the element is elevated and it decreases its resistance, with which it leaves to pass a greater electric current, which activates a static switch, which in some time closes a activating circuit of a luminous acoustic signal.
