Device for Measuring the surface temperature and the surface temperature measurement method

摘要

A method of measuring the surface temperature to measure the surface temperature of a Target material (W) temperature Measurement through the Detection,Making Use of a thermometer (1) of Light Radiation, the Thermal Radiation emitted from a surface of the target material (W) measurement of temperature in a Cooling process with water.The Method comprises: providing a Radiation thermometer (1) comprising a Light receiving Unit (11),And a housing (2) which has an opening on one side of material temperature measuring, storing in its interior, Housing,At least the Light receiving Unit (11) (1) of radiation Thermometer; bring an Optical Glass (3) configured to transmit Light of Thermal Radiation,Between the objective material (W) of temperature Measurement and the Light receiving Unit (11) of the Radiation thermometer (1)Where The Optical Glass (3) fit and sealed inside the casing (2); locate a Terminal surface of the Optical Glass (3) on one side of material objective Measurement of temperatureAdjacent to the surface of the target material (W) for temperature Measurement.And Measure the surface temperature of the target material (W) temperature Measurement; and provide a spacing Member.Configured to maintain a substantially Constant space between the surface of the target material (W) of temperature Measurement and the terminal surface of the Optical Glass (3),On the side of target material temperature Measurement; where the Light receiving Unit (11) of the Radiation thermometer (1) receives the Light emitted Thermal Radiation through the water andIs present in the space between the surface of the target material (W) of temperature Measurement and the terminal surface of the Optical Glass (3),On the side of target material for temperature Measurement.And where the surface of the target material (W) measurement of temperature on the thermometer (11) which detects the Light Radiation of Heat Radiation is a plane substantially verticalWith respect to a horizontal direction, and the space between the surface of the target material (W) of temperature Measurement and the terminal surface of the Optical Glass (3),On the side of target material temperature Measurement, is 1.0 mm or less.
