  • Page 17 User Guide Landcal Blackbody Source Type P1600B2 Note From information obtained via extensive testing, it has been found that when the thermocouple is inserted into the furnace by 470mm, the thermocouple temperature usually corresponds with the radiance temperature to within ±3°C / ±5.4°F. However, as each furnace will have slightly different properties, this position is only a general guide.

  • Page 22: Using The Furnace

    User Guide Landcal Blackbody Source Type P1600B2 Using the Furnace 6.1 Introduction The furnace has been designed to create an enclosure of uniform temperature, ideal for the calibration of radiation thermometers or thermocouples. The cone point of the refractory cavity target block installed in the furnace is placed in the area of minimum gradients within the furnace.
  • Page 23 User Guide Landcal Blackbody Source Type P1600B2 6.4 Control Thermocouple The thermocouple which controls the furnace temperature is situated close to the furnace heating elements, which will be at a higher temperature than the target cavity. The difference between controller set point temperature and target cavity temperature can be as high as 20°C / 40°F at 1500°C / 2700°F.

  • Page 24: Calibration Of Radiation Thermometers

    User Guide Landcal Blackbody Source Type P1600B2 Calibration of Radiation Thermometers 7.1 Preparation The furnace control setting is usually the normal working temperature of the thermometer to be tested. The target temperature is that indicated by the standard thermocouple in the ‘measuring’...
  • Page 25 User Guide Landcal Blackbody Source Type P1600B2 As the emissivity of the source is less than 1.00, the radiance temperature will be dependent on the wavelength of the thermometer under test. For example, a furnace operating at 1000°C / 1832°F with emissivity of 1.00 will show a temperature of 1000°C / 1832°F for a thermometer having a silicon cell (wavelength = 1µm) detector, and a temperature of 1000°C / 1832°F for a thermometer having a pyroelectric (wavelength = 8 to 14µm) detector.

  • Page 26: Calibration Of Thermocouples

    User Guide Landcal Blackbody Source Type P1600B2 Calibration of Thermocouples 8.1 Introduction Uniform temperature conditions are achieved along the length of the cavity, which allows the furnace to be used also for the calibration of thermocouples by the comparison method. This method consists of comparing the thermocouple under test with a standard thermocouple, the calibration of which is traceable to National Standards.

  • Page 27: Maintenance

    User Guide Landcal Blackbody Source Type P1600B2 Maintenance 9.1 Introduction Before starting any maintenance/repair work, always ensure that the furnace is disconnected from the electricity supply. Before starting any maintenance/repair work, always ensure that the furnace has been allowed to cool to room temperature. Upon completion of any furnace maintenance work, check the furnace for electrical safety before use.
  • Page 28 User Guide Landcal Blackbody Source Type P1600B2 If the furnace does not reach temperature, or is slow, measure the element resistances and calculate the required power limit using the method given above. If it exceeds 100%, the elements have too high a resistance and need replacing.
  • Page 29 User Guide Landcal Blackbody Source Type P1600B2 Inserting the new insulation cassette Lift the new insulation cassette into the case and slide it to the front. Refit the retainer at the rear of the body. Reconnect the element supply wiring to the terminal blocks on the rear of the new insulation cassette in the positions noted previously.
