What Exactly is Cold Junction Compensation? How Does It Relate to the Use of Thermocouples as Temperature Sensors?

Written by Dan Jackson, TEGAM Product Manager I was recently asked, “What does Cold Junction Compensation do?”  This question requires that I summarize how thermocouples work and the physics behind them. A thermocouple develops a thermoelectric voltage based upon the principle known as the Seebeck Effect. Now, what is the Seebeck Effect? In the 1800s, Thomas…

How Does A Digital Thermometer Work?

How do Digital Thermometers Work? Thermometers used to be simple. First, there was a glass tube filled with a liquid that expanded up the tube as the temperature increased. We all understood how that worked. Then came the bi-metal thermometers. They were made from a layered strip of 2 metals with different coefficients of expansion…
