What is the difference between temperature measuring electric tubular heater and ordinary electric tubular heater?
The temperature measuring electric cartridge heater is an electric heating tube with a built-in thermocouple. It means that the K-type or J-type thermocouple is placed inside the heating tube and can be used to detect the temperature of the heating tube.
Built-in K-type thermocouple temperature measurement range: -200~800 ℃
Built-in J-type thermocouple temperature measurement range: 0~400 ℃
Electric heating tube products with thermocouples are generally used in mold environments where space is limited but the heating tube needs to be prevented from overheating or reflect the mold temperature. If conditions permit, it is recommended to choose an external thermocouple to measure temperature. On the one hand, the external thermocouple can reduce maintenance costs, on the other hand, the external thermocouple can more accurately reflect the temperature of the mold.
In practice, the temperature measuring electric heating tube is not very different from the ordinary electric heating tube, but the temperature probe of the thermocouple is placed inside the heating tube, and then the positive and negative wires of the thermocouple are removed from the heating tube through the preset wiring. Lead out from the core rod inside the heating tube, thereby achieving the purpose of insulation protection.
The temperature measurement type electric cartridge heater has the same appearance as the ordinary electric heating tube, but the heating tube with temperature measurement function has a thermocouple independent signal line at the connection.
