Abstract
PURPOSE: To make it possible to detect a combustible gas without influence of an ambient temperature and an applied voltage, by providing a detection element provided with a carrier including a catalyst on a platinum resistor and a carrier including cobalt oxide on the platinum resistor and constituting a unit by provided them and a compensation element covering them with a ventilative cover.
CONSTITUTION: A carrier such as γ-alumina and a Pt-Rb catalyst are printed onto a platinum narrow wire coil to form detection element 7; and meanwhile, a platinum coil is printed to the carrier and is caused to include cobalt salt solution, and cobalt oxide is formed by heating to form compensation element 6, and these elements 6 and 7 are covered with a ventilative cover. Fixed resistors 8 and 9 and variable resistor 10 are connected to detection element 7 and compensation element 8 to constitute a bridge circuit, thus obtaining a contact burning type detection unit for combustible gas such as methane and butane.
