A thermocouple is a temperature sensor that works on the principle of Seebeck effect.

• Thermocouples are made of two different metals joined together at one end.

• When there is a temperature difference between the two ends, a voltage is generated.

• This voltage is proportional to the temperature difference and can be measured to determine the temperature.

• Thermocouples are commonly used in industrial applications for temperat...read more
