We split this important newsletter topic into two (2) parts:
In this Part 1 application note "Introduction to Thermocouples", we explore the history of the thermocouple from its origins in the 1820s right up to its modern usage today! In a short 3 pages, we present why thermocouples work the way they do, why you need signal conditioners to provide a high input impedance circuit to measure a thermocouple's voltage, how and why to provide 'cold junction compensation', and a description of linearization as well as other important measurement requirements. Part 1 is a quick summary of over 170 years of thermocouple temperature measurement technology! Add this newsletter to your library today!

Next time, in Part 2 we will expand beyond thermocouple technology and examine "Practical Thermocouple Temperature Measurements".
