Thermocouples

Thermocouples are sensors that measure temperature by generating a small electric voltage when two different metal wires are joined and exposed to heat. The voltage produced varies with temperature, allowing the device to determine the temperature accurately. They are widely used because they are durable, respond quickly, and can measure a wide range of temperatures. Essentially, they work on the principle that different metals create a voltage when heated together, which can be interpreted as temperature readings—making them reliable tools in industrial, scientific, and everyday applications.
