Page 63: Appendix A How Infrared Thermometry Works
Figure A-1 shows a block diagram of an infrared radiation thermometer. Energy from the object is focused by the lens onto the detector. As the detector heats up, it sends out an electrical signal, which in turn is amplified and sent to the circuitry of the thermometer. - Page 64 Appendix: How Infrared Thermometry Works Blackbody When thermal radiation falls on an object, part of the energy is transmitted through the object, part is reflected and part is absorbed. A blackbody is defined as an ideal object that absorbs all the radiation incident upon it.
- Page 65 T = temperature of object in Kelvin = temperature of ambient surroundings in Kelvin The infrared thermometer uses this equation directly in calculating the temperature of an object. The incident power is measured by the infrared detector. The emissivity of the object is determined by the user.
- Page 66 FOV, within which they see all objects. In particular, the thermometer will measure a fixed proportion of the energy radiated by all objects within its FOV. The user must guarantee that the distance between the thermometer and the object is defined so that only that object fills the FOV of the instrument.
-
Page 67: Appendix B Emissivity Values
Table B-1 provides guidelines for estimating the emissivity of various common materials. Actual emissivity, especially of metals, can vary greatly depending upon surface finish, oxidation, or the presence of contaminants. Also, emissivity or infrared radiation for some materials varies with wavelength and temperature. To determine the exact emissivities for most applications, follow the procedures in Appendix C. - Page 68 Appendix: Emissivity Values Material Emissivity (ε) Asbestos Board ......... . 0.96 Asphalt, tar, pitch .
-
Page 69: Appendix C Determining An Unknown Emissivity
Heat the object (or at least a sample of the object material) on top of a heating plate to a known temperature. Make sure the thermometer and the air surrounding the heating plate are at the same temperature. Measure the temperature of the object material with the thermometer. - Page 70 FOV of the thermometer. Area “A” Target Aim the thermometer at Area “B” as shown in Figure C-1 Make sure that Area “B” is as close as possible to Area “A”. Adjust the emissivity of the thermometer until the temperature reading equals the temperature found in Step 3.
- Page 71 C-1. Make sure that the painted area of object material fills the FOV of the thermometer. Aim the thermometer at another spot on the target - Area “B” in Figure C-1. Adjust the emissivity of the thermometer until the temperature reading equals the temperature found in Step 2.

Page 72: Addendum
• Power must be disconnected before making any electrical connections. • The power supply used to power the thermometer should be VDE or UL approved with the following ratings: Power: 7-24 Vdc @ 80 mA.
