Thermal resistance and thermocouple characteristics compared to what

A, if it is used in the same temperature, the thermal resistance on the output signal is larger, and more easy to measure; Second, the need for resistance test, you will need to use to the additional power supply; Three, because part of the thermal resistance of heat the whole size will be bigger, because the thermocouple on the working side belongs to small solder joints, so heat resistance on the temperature of the reaction must be much slower than the thermocouple; Four, the same material and heat resistance, no thermocouple when measuring the temperature of the high ceiling. So thermal resistance and thermocouple on the principle of temperature measurement is completely different, thermal resistance is mainly on the basis of resistance heating temperature measurement, so the resistance on the resistance, will change because of the change of the temperature, the thermal resistance of heat directly to the change of the resistance measurement, it is equal to the temperature was measured directly, currently on the market, the main can be divided into: semiconductor thermistor, and the heat resistance of two types of metals.
