Thermocouples Part 1

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".

Remember, our Application Engineers can assist you with signal conditioner selection over the phone or via fax and email. Call us at our manufacturing facility in Tucson at 520-741-1404 (fax 520-741-0762) or Email us at
