FIELD: physics.
SUBSTANCE: present invention can be used for gas analysis. Invention implies that sensor of gas analyser contains heating coil placed in tribrach with catalyst and shaped as hollow cylinder formed by coils of cast microwire representing leader covered with glass or glass-ceramic isolation. Coil ends are connected to holders fixed in sensor casing, microwire coils in heating coil being connected to each other with fixing layer. The said fixing layer is made of thermoplastic material having upper temperature limit within plastic condition range lower than microwire isolation melting temperature but higher than maximum operating temperature of sensor.
EFFECT: increased stability of thermal performance within wide range of operating temperatures, optimisation of sensor output signal relation to measured characteristics of gas medium.
