发明名称 Explosive gas detector
摘要 An explosive gas detector employing an electrically conductive element which, when powered, changes temperature in the presence of an explosive gas, and a control circuit which senses the increases in temperature and decreases the power input to the element as an inverse function of changes in temperature of the element. The level of electrical power provided the element is indicative of the concentration of explosive gas present.
