There are many types of thermocouples. According to your needs, the thermocouples you want to choose are also different. Next, I'll tell you how to choose thermocouple.
First, take a look at the temperature range of the thing to be measured.
According to the type of thermocouple, it can measure the temperature range is not the same. In general, the common thermocouple can measure the temperature is already very high, the minimum can be measured to - 2 Baidu, the highest can be measured to 1300 Baidu. And the special thermocouple can measure the temperature is higher, the highest can measure 2800 degrees, the lowest can measure 270 degrees below zero. Of course, there are many kinds of common thermocouple and special thermocouple. You have to look at the temperature range of what you need to measure, and then choose the thermocouple that suits you.
Second, durability.
Although the durability of thermocouples is generally very high, but in fact, different types of thermocouples, their durability is not the same. In fact, in general, the durability of the thermocouple and its price. Generally expensive thermocouple, it must also be more durable, and the quality of cheaper thermocouple is certainly worse. You can actually see how long you need to use this thermocouple. If it won't be long. You don't have to buy expensive ones. If you have been expensive for a long time, you can buy more expensive ones. Xiuwen still depends on your own ideas.
Third, take a look at what kind of thermocouple you need to measure.
Different types of thermocouples, it is applicable to different things. Because the function and usage of each type of thermocouple are different, when you buy a thermocouple, make sure that what you need to measure is more suitable for which thermocouple. So you can choose the type of thermocouple. Of course, if you don't know what kind of thermocouple you need to measure, you can check it online or ask someone directly.
Fourth, take a look at the response time you need.
Different types of thermal resistance reaction time is also different. Of course, the reaction time of thermocouple is usually very fast. But different types of thermocouple, its reaction time is certainly not the same. So, you need to pay attention to the reaction time you need. Of course, the price of thermocouple with different reflection time is also different. Therefore, you should choose the thermocouple according to the facts, so that you can select the thermocouple suitable for you.
In short, if you can do these things when choosing thermocouples, you will be able to choose the ones that suit you.
