NT93420 Temperature Transmitter Sensor Operating Principle
The principle of temperature measurement is that two different material conductors form a closed loop. When there is a temperature gradient at both ends, a current will pass through the loop. At this time, there is an electromotive force between the two ends -- thermoelectric electromotive force, which is called the Seebeck effect. The homogeneous conductor of two different components is the hot electrode, the higher temperature end is the working end, the lower temperature end is the free end, the free end is usually at a constant temperature. According to the functional relationship between thermoelectric emf and temperature, a thermocouple indexing meter is made. The indexing meter is obtained under the condition of the free end temperature at 0℃, and different thermocouples have different indexing meters.
