Product details
Multi point armored thermocouples consist of junction boxes (waterproof and explosion-proof), multiple armored thermocouple elements, installation and fixing devices (fixed threads and flanges), and other main components (protective tubes are provided by the user). They are widely used in industrial sectors and technological fields such as petrochemicals, power metallurgy, and machinery.
For waterproof junction box multi-point thermocouples, when the measuring end of each armored thermocouple element is a single branch, there can be 6 6-point thermocouples, and when it is a double branch, there can be 3 3-point multi-point armored thermocouples. For explosion-proof junction box multi-point thermocouple, each armored thermocouple element is a single type, that is, 3 3-point multi-point armored thermocouples. The remaining structural types are supplied according to technical agreements.
