FIELD: power engineering. ^ SUBSTANCE: invention refers to power engineering, and namely to temperature sensors used in gas burner devices for gas burning in boilers of outdoor installation, and can be used in domestic gas units for automatic temperature maintenance. Temperature sensor consists of a body with holes of gas supply to and discharge from gas regulator, an inner metal pin, an external tube submerged in heat carrier, temperature control screw device, at that, external tube is made of PE-Xb cross-linked polyethylene, inside the body there located is a slide valve, body together with tube and metal pin are installed in boiler water heating jacket sleeve; at that, pin is provided with a groove wherein there fixed is an elastic element, inside external tube and body of sensor there installed is a heat-conducting metal pin the edge of which is submerged in heat carrier and isolated therefrom by heat-insulating washer. ^ EFFECT: simplifying the design, decreasing overall dimensions and increasing axial movement of metal pin, and reducing actuation error. ^ 1 dwg |
