【Abstract】 The measurement and control of heating temperature is of great significance to the process of the heat-pushing unequal bending tube. According to the theory of radiation temperature measurement, the system of photoelectrometer temperature measurement based on a single-chip computer is designed. The radiant temperature of the object to be measured is used as the real temperature in the measurement system. The measurement error is corrected by the looking up tables program of the single chip computer. The relative error is less than 1% in the range from 500 ℃ to 1000℃. The valid means of the measurement and control of temperature of the heat-pushing unequal elbow on a core bar is offered by the photoelectrometer temperature measurement system.更多还原
