Thermal resistance measurement principle and thermocouple temperature measurement principle difference is the main proof thermal resistance, thermal resistance is based on the thermal effect resistor for temperature measurement, ie the resistance of the resistor changes with temperature change characteristics. Therefore, as long as the measure of the change in resistance warm sense resistor, you can measure the temperature. Currently there are metal and semiconductor thermal resistance thermistor categories. Third, sub-proof thermal resistance from the material wholesale resistance, which is a metallic material, heat-proof metal material having a temperature-sensitive resistance variations and thermocouple bimetallic material, both of two different metals, due to changes in temperature, at both ends of the two wires of different potential difference. Fourth, the two sensors to detect temperature range is not the same degree of resistance generally detect temperature range 0-150 (of course you can detect negative temperature), the thermocouple can detect 0-1000 degrees C temperature range (or even higher) Therefore, the former is a low temperature detection, which is the temperature detected. Explosion RTD wholesale, force measuring instrument since proof thermal resistance, heat resistance, Fujian proof provided by the Shanghai Automation Instrumentation Co. measured.
