How do these types of thermocouples work?

A thermocouple is a temperature measuring device that uses the phenomenon of electrical thermo-conductivity to measure temperature. It consists of two wires of different materials welded together at one end. As the temperature of the soldered end increases, the difference between the two wires increases proportionally.

It is used, among other things, in high-temperature or high-pressure environments, such as gas heaters, air-conditioning and refrigeration systems, and industrial temperature measuring devices.

How to choose a thermocouple?

There are several factors to consider when choosing a type of thermocouple, here are some general steps to follow when choosing the right type of thermocouple:

Determine the temperature range to be measured

Different types of thermocouples have different temperature measurement ranges, so it is important to choose a type that is appropriate for the specific temperature range you are measuring.

Consider the measurement environment

Some types of thermocouples are more resistant to corrosion, high pressure or other extreme conditions. It is important to choose a type that is appropriate for the environment where it will be used.

Think about the accuracy of the measurement

Some thermocouple specifications offer better accuracy than others, depending on the application. Therefore, it is important to choose a type that is suitable for the accuracy needed for your application.

Consider chemical and mechanical properties

Elements of measurement. This may include corrosion resistance, dimensional stability, heat resistance, etc.
