thermocouple of attention to the use

Thermocouple is a kind of product that can be seen in many places. If we want to choose thermocouple, most people may think of various precautions about thermocouple, and what should be paid attention to in the process of using thermocouple in the world. This is a thing that many people want to know, if we want to use thermocouple In this case, all aspects should be considered.

1> When the thermocouple is used, we can look at the compensation wire. We should select the appropriate compensation wire according to our own actual situation. Generally speaking, the compensation wire should be correctly selected according to the type of thermocouple used or the occasion used. For example, when selecting the compensation wire, we should consider the working temperature of the surrounding environment Generally speaking, the working temperature of the environment is between - 20 ℃ and 100 ℃.

2> Thermocouple in the actual use process, must connect two nodes, and as close as possible to them, try to maintain the temperature of the two nodes, in the same case, the whole instrument in the process of connection, as far as possible to make the instrument temperature consistent, so that the meter cabinet to ensure that the front, in the place where there is a fan contact to protect, do not let The fan blows directly to the node.

3> When the thermocouple is used, the signal strength should also be considered. Generally speaking, if the signal strength is used for a relatively long distance, then the whole signal will show the phenomenon of attenuation, and the strong electricity in the environment will constantly produce interference, and when the control is more serious, the temperature will fluctuate.
