Abstract
Improvements in gas detection devices, characterized in that each device is equipped with at least one gas detector element; an alternating current power source for feeding a low alternating current voltage through the electrodes of said detector element; means for converting the variation of said element into a potential value comprising said gas detector element as one of its essential circuit components, and an amplifier connected to the output of said potential difference comparator, to thereby detect the variation of resistance of said element in proportion to the concentration of gas, while avoiding the undesirable self-heating of said element.
