Beschreibung
Zusammenfassung:	The proposed catalytic thermal detector for inflammable gases can be used in gas analyzers, specifically in gas analyzers designed for detecting methane in mines. The detector contains a measuring sensor and a compensation sensor, which are inserted in a bridge measuring circuit, a current regulator for the sensors, an amplifier for amplifying the output signal of the measuring circuit, a comparator designed for generating an alarm signal, and additionally, a circuit for shunting the measuring sensor and an additional comparator for generating a continuous alarm signal. The input of the shunting circuit is connected to the output of the amplifier, and the output is connected to the output of the measuring sensor. The input of the additional comparator is connected to the output of the compensation sensor, and the output is connected to the output of the comparator for generating an alarm signal.
