The first step of installing a thermocouple is to install them. Correct installation can make the work efficiency higher and the measurement accuracy is more accurate. Improper installation may cause errors or even damage. Thermocouple connection method: In fact, the thermocouple connection has a bipolar, that is, the positive and negative electrodes. If we observe, we can see the scale on the wiring board. Each of the above:+,-, but some manufacturers do not have positive and negative. If this happens, we need to judge based on experience:
It recognizes the color, green polarity and gray polarity at the connection. Measure it with a temperature meter. Check the temperature after the wiring. If you have suction, you can also judge through magnets. The compensation line also requires that the wiring is correct and positive and negative. When connecting the instrument, pay attention to the positive and negative pole. Generally speaking, there are labels on the wiring board. If you cannot wiring, please refer to the instruction manual. Regarding the connection of the thermocouple, it is also necessary to pay attention to the general terminal cannot be used for connection, because the conductive bar of the terminal is generally made of special copper materials, such as electrolytic copper, unlike the copper material that constitutes the electric puppet, and the general general, and generally Different from the combined terminal.
The guide bar of each thermocouple is made of different metal materials. For different types of thermocouples, different wiring terminals should be set. When the thermocouple transmission is transmitted, the conductivity data that needs to be used is completely consistent with the conductivity data of the thermocouple to ensure the accuracy of the signal transmission. In industry, thermocouple combination is used as a temperature sensor, which is often used with monitors, recorders and electronic regulators. The instrument can directly measure the surface temperature of liquid, steam, gas medium and solid in various production processes, and range from 0 ° C to 1800 ° C.
