\"Thermocouple<\/a>A\u00a0thermocouple is a type of sensor used to measure temperature. A Thermocouple is a welded joint of two dissimilar metals known as bimetallic welded joint.<\/p>\n

How does a Thermocouple Operate?<\/h2>\n

The operational principle is that a temperature difference between two dissimilar metals produces a small voltage and this voltage will be proportional to the temperature at the joint. This is known as Seebeck effect. By measuring this voltage, the corresponding temperature can be measured. By measuring this voltage, the temperature can be manually calculated or can be directly displayed using electronic display instruments as commonly done. Unlike other sensors, a thermocouple sensor does not require any external power.<\/p>\n

Thermocouple elements are used in all industrial and commercial applications where temperature needs to be measured. To utilize a thermocouple as a power source you need another thermocouple working at an alternate temperature.<\/p>\n

Categories of Thermocouple<\/h2>\n

Different thermocouple sensors are known by their type numbers such as Type J, K, N, T, etc. which are used for different applications, different temperature ranges, etc. Brief technical details are listed here:<\/p>\n
