Abstract

PURPOSE:To form titled detecting apparatus having simple construction and facility for maintenace, by jointly using an igniting element of hydrogen flame with a detecting element for flame extinction (resistor). CONSTITUTION:The resistance bridge RB is constituted by the detecting element of ignition and flame extinction IC/R jointly used the ignition coil (heating resistor) with the resistance for detecting the flame extinction (resistor for temperature detection) and the resistance R1, R2, R3, in the gas analyzer using the gas to be analyzed AG introduced into the nozzle NL, the air AR and the hydrogen flame HGF obtaied by burning the hydrogen HG. Turning the switch IS to the ignition power source IP side, ignite said flame HGF by heating the element IC/R, then turn the switch IS to the bridge RB side, output is not generated from the comparator COMP because the bridge RB is balanced in the ordinary condition. When said flame HGF is extinguished, the resistance value of the element IC/R is made small and the alarm ALM is outputted from the comparator COMP as the bridge RB is made unbalanced.
