Description
Technical field
The utility model discloses a kind of optics temperature probe, belong to heat radiation temperature measuring device equipment technical field.
Background technology
Sensor for measuring temperature commonly used is a platinum rhodium thermocouple, and its deficiency is the cost costliness, consume the precious metal material, the life-span is short, easily be influenced by the adverse circumstances etc.
Summary of the invention
The utility model provides a kind of easy to use at the deficiency of prior art, has the optics temperature probe that thermometric is direct, accurate, the life-span is long, corrosion-resistant, not influenced by rugged surroundings.
Technical characterictic of the present utility model is according to stefan boltzmann's law: blackbody radiation power is proportional to the biquadratic of its absolute temperature.Adopt temperature-sensitive pipe heating temperature to raise, the tube chamber end produces radiant light, high temp glass is isolated high temperature, can allow heat radiation light penetrate again, optical lens focuses on light activated element sensor sensitive surface with heat radiation light, light activated element sensor distance lens focus position-adjustable is with the property difference that adapts to different sensors and overcome machining error.
Structure of the present utility model is such: a kind of optics temperature probe, it is characterized in that by the stationary pipes of band mounting flange and the check nut and the fastening temperature-sensitive pipe of the reduced pipe in the stationary pipes of stationary pipes one end, the end of temperature-sensitive pipe connects temperature-sensitive pipe fixed cover, by clamping nut the end of temperature-sensitive pipe is fixedlyed connected with an end of temperature-sensitive pipe fixed cover, in the temperature-sensitive pipe fixed cover heat insulation high temp glass is installed, the other end of temperature-sensitive pipe fixed cover is connected with optical module.
Optical module is formed by aperture, plano lens, light activated element and light activated element governor motion are installed in the tube of hollow successively.
During work, when the rising of temperature-sensitive pipe heating temperature, the tube chamber end produces radiant light, and radiant light enters lens focus through aperture behind high temp glass, enter light activated element through lightlng hole.The voltage signal of light activated element output inputs to the optical temperature Displaying Meter, demonstrates corresponding temperature.Because temperature-sensitive pipe and photoelectric commutator structural member constitute closed cavity, radiant light is propagated in cavity, has avoided interference such as steam, dust.Daylighting face and optical system fixed distance, the temperature-sensitive tube material is fixed, and in process of production, calibrates optics temperature probe absolute error≤0.5% through standard couple on high temperature furnace.
The utility model can use in 800 ~ 1900 ℃ of temperature-measuring ranges, fundamental error≤0.5%, and long service life, all more intense to the adaptive faculty and the antijamming capability of rugged surroundings, generally do not need to set up air-cooled water-cooling system; Can avoid the pollution to light path such as dust, cigarette, steam; Do not need compensating wire.Compare and use the thermopair of precious metal cheap, can directly utilize the installation perforate of original thermopair to install and fix the occasion that also is difficult to use: strong corrosive medium, strong-electromagnetic field, high temperature kinetic measurement etc. applicable to thermocouple.It is the ideal product that replaces thermopair under the hot environment.
