How Thermocouples Work

The video tutorial explains the working principles of thermocouples and RTD sensors. It covers how thermocouples measure temperature by connecting two different metals and reading the voltage difference. The video also discusses the calibration process using known temperatures and the use of ice baths for accuracy. Additionally, it introduces RTD sensors, which measure temperature through resistance changes in materials like platinum. The tutorial provides analogies to help understand voltage and pressure differences, and it highlights the practical applications and limitations of these temperature measurement devices.
