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…Read more
Digitizing Temperature Measurement for Product Safety and Quality
TEGAM President Adam Fleder gave an interview to Process Expo recently on the importance of accurate temperature measurement and data collection in Food Safety applications. Here's a bit of the article, below: "'People don’t just want a thermometer,' TEGAM president Adam Fleder says. 'They don’t even care if they have a thermometer. What they want…Read more
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…Read more
