Description
Technical field
The utility model relates to a kind of thermal resistance, particularly relates to a kind of thermal radiation resistance type thermal resistance.
Background technology
Thermal resistance is conventional a kind of temperature detector, and Thermistor Temperature Measurement increases this characteristic based on the resistance value of metallic conductor with the increase of temperature to carry out thermometric, has measuring accuracy high, steady performance.For the thermal resistance temperature sensor of thermometric in the insertion stove generally used now, the heat radiation sent is heated, easily cause temperature sensor operational failure, damage by high temp objects; And existing thermal resistance adopts the protective sleeve of ceramic material, has in operational process
heat transferand radiation loss, in order to reduce measuring error, thermal resistance has enough insertion depths, for the tested region that temperature constantly changes, process instantaneous variation, require that the response of sensor is fast, and the temperature changing speed that common temperature sensor does not only catch up with measurand occurs delayed, and measuring error can be produced because not reaching thermal equilibrium.
Summary of the invention
According to above technical matters, the utility model provides a kind of thermal radiation resistance type thermal resistance, comprise thermal resistance body, terminal box, electric conversion joint, porcelain bushing, fixed cover, it is characterized in that: also comprise TSic temperature sensor, metal coating shell, joint flange, ceramic fiber layer, described thermal resistance body is provided with terminal box, one end of described terminal box is connected with electric conversion joint, one end of described thermal resistance body is connected with porcelain bushing by fixed cover, the inside of described porcelain bushing is provided with TSic temperature sensor, the outer cover of described porcelain bushing is provided with metal coating shell, described metal coating shell is provided with joint flange, ceramic fiber layer is provided with between described metal coating shell and porcelain bushing.
Described metal coating shell is provided with polytetrafluorethylecoatings coatings.
The beneficial effects of the utility model are: the utility model provides a kind of thermal radiation resistance type thermal resistance, be provided with metal protection cover, strengthen hardness of the present utility model and shock resistance, explosion-proof capabilities, metal protection cover scribbles tygon tetrafluoro, there is moisture resistance, anticorrosion, fire-retardant performance, can effectively extend its serviceable life; Between porcelain bushing and outside metal protection overlap, be provided with ceramic fiber layer, effectively can strengthen its insulation ability, strengthen its thermal radiation resistance performance, avoid temperature sensor heated by the heat radiation that high temp objects sends and cause damaging; Use TSic temperature sensor to replace other temperature-sensing elements, fast response time, precision are high, stable, avoid producing measuring error.The utility model structure is simple, temperature survey response is fast, precision is high, has good thermal radiation resistance performance.
