In the metal smelt process, need carry out thermometric to the metal of melting, with the various parameters in the adjusting process process, guarantee to smelt qualified metal material.In the smelting process, generally use disposable quick temperature measurement method at present, promptly adopt the disposable thermal galvanic couple, the temperature probe that will have platinum rhodium or Wolfram rhenium heat electric couple inserts in the motlten metal, after thermometric finished, sensor generally can only use once owing to the effect that is subjected to high-temperature metal damages.Someone adopts mode thermometrics such as photoelectricity, but the cost height.
The utility model content:
The utility model purpose provides a kind of device of measuring temperature of high-temp liquid, improves the serviceable life of sensor, guarantees temperature measurement accuracy and reliability, reduces cost, and solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the device of measuring temperature of high-temp liquid is made up of outer protection tube and sensor two parts, and sensor places among the outer protection tube that constitutes with a kind of material, and sensor is connected with intelligence instrument by compensating wire.
Sensor can be a thermocouple sensor, also can be photoelectric sensor, or miniature CCD stylus, silicon photocell, photoelectric tube, infrared temperature sensor etc.
When adopting the utility model that high-temp liquid is carried out thermometric, sensor is converted to electric signal with temperature signal, by compensating wire signal is sent into intelligence instrument, by intelligence instrument to its change, analysis and Engineering Thermodynamics calculate, try to achieve the actual temperature of high-temp liquid, and show.Because sensor places among the outer protection tube, the protection sensor does not damage under hot environment, improves serviceable life, guarantees measuring accuracy and reliability, improves the adaptive capacity to environment of sensor.
The utlity model has characteristics such as long service life, temperature measurement accuracy height, cost be low.This sensor use cost is than adopting the fast thermocouple cost to reduce 10-20%, and than adopting photoelectricity thermometric mode cost to reduce 40-50%, result of use is more reliable and stable than fast thermocouple thermometric mode and photoelectricity thermometric mode.
