| 1 | This paper is about the platinum resistance temperature sensor measurement research. | |
| 2 | Moreover, significant gas analysis and temperature measuring forecast method were expounded. | |
| 3 | The importance of temperature measuring and sampling system in steel production is expatiated. | |
| 4 | The precision of the thermometer is very high because of applying sensor nonlinear compensation technique through software. | |
| 5 | The measuring temperature was realized with infrared thermometry method using infrared sensor. |
