What role does the thermal resistance in glass production? Thermal resistance temperature measurement principle is: the thermal resistance of the resistance value is changing with the temperature, semiconductor ceramic thermistor is a negative temperature coefficient, the higher the temperature, the lower the resistance, the copper heat resistance and platinum thermal resistance is positive temperature coefficient, the higher the temperature the higher the resistance, they are a necessary requirement, is very repeatability and linear. Thermocouple temperature measurement principle is: thermocouple temperature measurement fundamental principle is to put the two different materials of conductor or semiconductor welding, forming a closed loop. Due to two different metal carries different number of electrons, when two conductor when there is a temperature difference between the two fixation point will have high potential to low potential discharge, thus constitute the current in the circuit, the bigger the temperature difference, the greater the current, this sight is called thermoelectric effect, also called the seebeck effect. Thermocouple is using this effect to the task.
