Description
Technical field
The utility model relates to Thermocouples Technology field, particularly relates to a kind of blast furnace platinum rhodium thermocouple.
Background technology
Thermopair is temperature element conventional in temperature measuring instrument, thermopair directly contacts with measurand and carries out thermometric, the ultimate principle of thermocouple temperature measurement is the conductor composition closed-loop path of employing two kinds of unlike materials, when there is thermograde in two ends, just have electric current in loop to pass through, now just produce thermoelectric effect between two ends, two ends temperature difference is larger, and electric current will be larger.The measuring accuracy of thermopair is high, measurement range is wide, simple structure, easy to use, its range of application is widely.
Traditional blast furnace platinum rhodium thermocouple, platinum filament and platinum-rhodium wire weld formation closed-loop path and armouring forms.Assembled by ceramic pipe, ceramic core and terminal box, due to the architectural feature of conventional ceramic, its heatproof is at about 1600 degree, and elevated temperature strength is low, and coefficient of heat conductivity is low, and rapid heat cycle is easily broken.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of blast furnace platinum rhodium thermocouple.
The utility model is achieved through the following technical solutions:
A kind of blast furnace platinum rhodium thermocouple, include double-layer carbon SiClx protection tube, high-temperature insulation corundum core, double platinum rhodium silk, terminal box and nickel-base high-temperature transition metal pipe, it is inner that described high-temperature insulation corundum core is contained in double-layer carbon SiClx protection tube, described double platinum rhodium wire bond connects and forms closed-loop path and be placed in high-temperature insulation corundum core, described double-layer carbon SiClx protection tube, high-temperature insulation corundum core, double platinum rhodium silk is combined into one, the right-hand member of described double-layer carbon SiClx protection tube is welded by high-temperature oxydation copper glue with the left end of nickel-base high-temperature transition metal pipe, the right-hand member of nickel-base high-temperature transition metal pipe is fixedly connected with described terminal box by screw, the dirty mouth of exhaust is left between described double-layer carbon SiClx protection tube.
The utility model has the advantages that: the utility model can normally use under High Temperature High Pressure mal-condition, accurately can carry out thermometric, physical dimension can flexible design, thermoelectricity capability is highly stable, and thermal response time is very short, and antioxygenic property is very strong, elevated temperature strength is almost identical with low temperature intensity, coefficient of heat conductivity is high, and swollen coefficient is very little, and rapid heat cycle is not easily broken swollen.
