Thermocouples are the most common equipment for electrical temperature measurement in the industry. The thermocouple mechanism is based on the Seebeck phenomenon, which converts the temperature difference between two points into voltage. In a more general definition of thermocouple, it can be said that: Thermocouple is a sensor that measures temperature. It consists of two metals and these two different metals are connected at the end. When the junction of two metals is heated or cooled, a voltage is created that can be proportional to the temperature. Thermocouple is a simple, robust and affordable temperature sensor that is used in a wide range of temperature measurement processes.
Thermocouples are generally used in a wide range of applications due to their ability as temperature sensors - from an industrial thermocouple to a common thermocouple found in electrical installations and common appliances. Due to the wide variety of models and their technical specifications, it is very important to understand its basic structure, how it works, and its ranges to better determine the right type and material of thermocouple for your application.
Thermocouples come in a variety of styles, such as thermocouple probes, thermocouple probes with connectors, transfer joint thermocouple probes, infrared thermocouples, bare wire thermocouples, or even wire thermocouples. Thermocouples are commonly used in a wide variety of applications. Considering the wide variety of models and their technical specifications, but understanding the basic structure, performance and scope is very important to better determine the right type of thermocouple and the right thermocouple material for the application.
Types of thermocouples:
It should be noted that thermocouple sensors are available in different types in the market, and these types are divided based on the type of metal used in the thermocouple sensor to measure different temperature ranges. These types are:
Thermocouple type K, j, T, E, N, S, R, B, each of which covers a specific temperature range, and you can choose one of these types according to your project.
