Thermocouple: Principle,working,& types
The world is in twenty first century & this era is of technology.Heat is an energy and a fundamental need for lives.In this time of technology advancement every thing is works on specific parameters that's why it is necessary to know accurate values of every input and output. Same thing applied in everything where hot work is going to be that is Temperature. To measure the temperature a sensor device is used known as Thermocouple Thermocouple is a sensor or device which is used to measure the temperature. Now the question arises that temperature can be measured by thermometer or mercury tube But they are used only for limited temperature range. To measure the temperature above and below the range of normal thermometer, thermocouple is used. Thermocouple consist of two wires of different conducting (both electricity and heat) material joined in a loop making couple. So thermocouple is a couple made by two wires to measure...
