Temperature Sensors, Thermocouple Sensor
The thermocouple consists of two wires made of different materials, which are welded together at the end. After the ambient temperature of the unheated part is measured, the temperature of the heating point can be accurately known. Because it must have the conductor made of two different materials, it is called the thermocouple. The thermocouples made of different materials can be used in different temperature ranges, and their sensitivities are different from each other. The sensitivity of a thermocouple refers to the change in the output potential difference when the temperature of the heating point changes by 1°C. For most metal-supported thermocouples, this value is between 5-40 µV/°C.

PT100
Pt100 is a platinum thermal resistance, and its resistance value is proportional to the change of temperature. 100 after PT means that its resistance value is 100 ohms at 0°C and about 138.5 ohms at 100°C.

Couples should not be installed too close to the door and heating place, and the insertion depth should be at least 8 to 10 times the diameter of the protection tube; the interval between the thermocouple protection bushing and the wall is not filled with insulation material, resulting in furnace heat overflow or cold air intrusion. Therefore, the interval between the thermocouple protection bushing and the furnace wall hole should be blocked with refractory mud or asbestos cord or other insulation materials so that the accuracy of temperature measurement will not be affected by hot and cold air convection; The cold end of the thermocouple is too close to the furnace, causing the temperature to rise above 100℃; thermocouples should be as far away as possible from strong magnetic and electric fields, so the thermocouples and power cable should not be installed in the same conduit to avoid deviation caused by interference; thermocouples can not be installed in the area where the measured medium rarely flow. Thermocouples must be installed against the direction of the flow and in full contact with the gas when the tube gas Temperature Sensors is measured by thermocouples.
