Temperature Measurements Through Dust or Steam for Energy-Intensive Industries
Abstract
The precise measurement of temperature in
energy-intensive processes can lead to energy
conservation and improvements in the quality and
consistency of products. While temperature
measurement instruments are available for a wide
variety of industrial situations including those which
prevent direct contact with the material, airborne
particulates can make remote process temperature
measurement difficult or impossible. We have
developed a prototype remote temperature
measurement instrument which can "see" through
clouds of dust, steam, smoke, or other obscuring
particles that prevent the proper operation of infrared
temperature sensors. The new instrument uses
wavelengths in the microwave range to sense
temperature. Its operation is entirely passive and
therefore harmless to personnel or products. Its
accuracy after calibration is comparable to that of
infrared temperature sensors, and its anticipated cost
when in production will be comparable to existing
remote temperature instrumentation.
