FIELD: thermocouples for stove gas burners. ^ SUBSTANCE: proposed thermocouple has hot junction on upper part of small mass and part in form of truncated cone which has flame receiving wall of preset axial length and deflection angle adaptable to shape of flame for reduction of temperature gradient between flame receiving wall and hot junction. Outer sleeve is connected with tubular base of larger diameter for cold junction by means of tubular base. ^ EFFECT: quick switching-off of drive after extinguishing of flame. ^ 7 cl, 5 dwg |
