  • The German Space Agency (DLR) commissioned Dornier GmbH to construct the Tiegelfreies Electromagnetisches Prozessieren unter Schwerelosigkeit (TEMPUS) facility for conducting containerless experiments on metallic samples in low earth orbit. TEMPUS, utilizing electromagnetic positioning and heating, was flown on the IML-2 Spacelab mission in July 1994 and is scheduled to fly again on the MSL-1 mission in March of 1997. TEMPUS requires non contact temperature measurement. In particular, nucleation and heat capacity measurements have special requirements for accurate temperature measurement. For these measurements, the facility has optical pyrometer capabilities at the specific wavelength of 633 nm as well as the integratedmore » wavelength ranges of 1,000 to 2,500 nm and 3,000 to 4,000 nm. The instrument and calibration procedures are described herein. The uncertainty in the temperature measurement on TEMPUS has been quantified, and the implications on the accuracy of nucleation and heat capacity measurements is discussed.« less
  • Current methods of exploding wire particle combustion temperature measurement techniques are reviewed and the theory and techniques of two-color photo-pyrometry (TCP) for moving particles are detailed. TCP was developed to measure the temperature of particles ejected from moving particles. Numerical expressions are defined for the black-body radiation, the actual radiant intensity, and the total power emitted by a particle through monochromatic filters. The formulas are employed to predict the resulting film exposures for two monochromatic photographs with two cameras and account is taken of errors in measured temperature, film density, film calibration and emissivity. Sample results for exploding aluminum wiresmore » in steam obtained with a microdensitometer, ASA 3200 film, a 1 kW quartz-halogen lamp, and 480 and 650 nm filters are provided. A maximum temperature of 3360 K was registered and considered accurate to within 5.7 percent.« less

  • The objective of the research was the development of a fiber-coupled, optical pyrometer for continuous temperature measurement in a vacuum degasser that reduces process time, enhances process control, and eliminates manual or robot-operated thermocouples. Through the live testing performed at US Steel's Edgar Thompson Works, the challenges associated with making optical temperature measurements in a vacuum chamber were identified. As a result of these challenges it was determined that continuous temperature monitoring in RH-type degassers was not a viable alternative to standard immersion thermocouples. The project was not successful.
