There are many portal sites on the Web leading to more details, but our page attempts an overview of this important use of temperature and humidity sensors.

  • STEEL INDUSTRY TEMPERATURE SENSOR MEASUREMENTS
  • SLAG DETECTION BY IR THERMOGRAPHY
    A unique application pioneered in the Steel Industries of the world. Includes access to two full-text technical papers and a PPT slide presentation.
  • INFRARED RADIATION THERMOMETER MEASUREMENTS AND USES
    A reasonably mature area of this site with links to vendor pages that provide applications information, some in great depth. It is planned to expand this section greatly in the near future with actual full-text papers, like some of the steel mill applications (above), since the primary author of the site has much experience in the field.
  • MEDICAL USES OF TEMPERATURE SENSORS
  • THERMOCOUPLE MEASUREMENTS
  • THERMOGRAPHY APPLICATIONS
    Recently enhanced with major page revisions, three new related pages and an expanded vendors page.
  • RTD MEASUREMENTS (Under Construction)
  • THERMISTOR MEASUREMENTS (Under Construction)
  • LIQUID IN GLASS THERMOMETER MEASUREMENTS (Under Construction)
  • FIBEROPTIC THERMOMETER USES (Under Construction)
  • OTHER TEMPERATURE SENSOR APPLICATIONS (Under Construction)
  • TEMPERATURE MEASUREMENTS: REFERENCE BOOKS AND PAPERS
    This link takes you to our reference list of books and published works that contain among them a wealth of information on how temperature sensors are used, the recommended limits of use for each type and much more.
  • As stated elsewhere in this web site (or at least implied), there is little excuse for not reading the literature! Most everything you want to do has been done before and the details are written down.

    So open your eyes, swallow a bit of your ego and read!

    Good luck and best wishes. If you have some interesting success, let us know and we’ll help you share that with others who visit these pages.

    That’s an Internet tradition and the way we both grow.

    Thanks for visiting.

    1. Question: I am testing the survival of Chinese Mantises in their eggcases during a prairie burn and need to know the temperature at the varying heights at which the eggcases will be elevated on a chain in the fire. I am not sure what temperatures to expect but a lot of fuel exists. I likely need a contact temperature sensor. Cost is a consideration as this will be totally out of my pocket. Any guidance much appreciated. Mark

    2. An interesting question! One that really deserves to be answered separately by each manufacturer, I think.

      However, a proper and traceable calibration certificate should go a long way towards insuring some sort of confidence that a specific device is “linear” as you have defined.

    3. I am looking for information showing that yes, ratio thermometers (two color instruments) are “linear” – meaning that they interpret radiation from 2 wavelengths of a black body source to produce a temperature reading that agrees with what Plank’s Law would produce, if one were to make the calculations ‘manually.’ Specifically, I am involved with an Ircon Modline 5, but the question probably goes to every IR thermometer.

      Yes, manufacturers assure us that their instruments are linear. On what basis do they say that?
