What is the difference between thermocouple and electric heating tube? How to choose the right one? 

Thermocouple and electric heating tube are the same kind of components, which are very common in the industrial field. However, its function is completely different from that of an electric heating tube.

 A thermocouple is an instrument used to measure temperature. It is very common in the industrial field. In some industrial fields, you need to use a stove to work, and you need to use a thermocouple to measure the temperature before it can work normally. The feature is very prominent, it can cooperate with other components to carry out a temperature automatic control, it is different from mercury to measure temperature, mercury temperature measurement will only be at a certain equivalent value, mercury is mostly used in medical treatment and daily life. 

The material of the thermocouple is made by welding two different metal wires together. When measuring the temperature, the temperature can be measured by these two metal wires, and the temperature can also be automatically controlled. Of course, the premise is Set the temperature range artificially. 

The quality of the electric heating tube is directly related to the length of the service life of an electric heating product. Therefore, when choosing electric heating tube components, we should pay more attention to it.

Then how can we distinguish between the good and bad of the electric heating tube?

 1. Look at the insulation effect of the electric heating tube. The insulation effect of the electric heating tube is mainly determined by the sealing process of the electric heating tube. The more refined the process, the better the insulation effect. 

2. Life, affecting the life of the electric heating tube mainly depends on the quality of the electric heating tube material. As we all know, the electric heating tube is made of magnesium powder. The higher the purity and the finer the density, the service life of the electric heating tube will be greatly enhanced. 

3. Corrosion resistance. When the electric heating tube is finished working, it will produce a certain amount of water heat. The water heat will gradually corrode the electric heating tube. In addition to daily maintenance, it is determined by the material. It is still based on the magnesium powder. Material, the better the material, the better the corrosion resistance.
