Thermocouple terminals installed is thermocouple used in step, can make correct installation of thermocouple work efficiency, more accurate and higher measurement precision and installation errors may cause thermocouple measurement errors, and even cause the damage of the thermocouple. Thermocouple wiring methods: actually thermocouple wiring is the distinction between, namely the positive and negative, if we look at, can see calibration on the wiring board. The above calibration respectively are: + and - , but also some manufacturer no positive and negative, if you met such a situation, we need through the experience to determine: one, is the color of the wiring place to distinguish, the green anode, gray as the cathode. Second, use a thermometer to measure it. Three, look at the temperature condition after wiring. Four, if it's suction magnets can also be used to determine. Five, compensation conductor need correct wiring, also has the positive and negative. Six, connect the instrument, we should also pay attention to is the cathode, usually a terminal has marked above, did not look at the instructions. When the thermocouple wiring, we also note that gm cannot be used in the thermocouple wiring terminals, because the guide bar inside the terminal is usually made of special copper material such as electrolytic copper, and copper material is different of the thermocouple, and the combination of general terminal by providing different, thermocouple terminals is provided in pairs. Each article diversion to the thermocouple terminals are made of different metal materials. According to different types of thermocouple and corresponding different terminals. Conductive material used in the thermocouple in the terminal should be exactly the same as that of thermocouple of conductive materials, thus ensuring the thermocouple signal in the process of transmission accuracy. Industrial prefabricated thermocouple as the temperature transmitter usually meter with digital display tables, records and electronic regulator. It can directly measure all kinds of production process from 0 ℃ to 1800 ℃ range of liquid, steam and gas medium, as well as the surface temperature of the solid. Transmitter usually and digital display table, recording instrument and electronic regulator. It can directly measure all kinds of production process from 0 ℃ to 1800 ℃ range of liquid, steam and gas medium, as well as the surface temperature of the solid.
