A thermocouple is a temperature sensor that consists of two dissimilar metal wires joined at one end, creating a junction. When the junction is heated or cooled, it produces a small voltage (known as the thermoelectric effect) that correlates with the temperature difference between the junction and the other ends of the wires. This voltage can be measured and converted into a temperature reading.
Working Principle: Based on the Seebeck effect, where a voltage is generated at the junction of twodifferent metals when there is a temperature gradient.
Thermocouples are valued for their wide temperature range, durability, and fast response time, making them versatile tools for temperature measurement in many applications
When selecting an RTD, it’s essential to consider the specific requirements of your application, including temperature range, accuracy, and environmental conditions
