Thermocouple – the best temperature sensor
We are very well aware of the fact that the temperature can be measured by using certain devices, and Thermocouple is known to be the best one that can measure and control the temperature accurately. This thermocouple is most useful device in the world of science and industry as there are many devices or machines that use this particular device for their functioning. This is a good sensor and is self powered that does not need any external excitation to work. This is also widely used for the conversion of heat into electricity in certain conditions. There are diesel engines, gas turbines and other kinds of machinery that are built using this device as the key role.
Thermocouple is a combination of two metals that produce voltage proportional to the temperature. This device is known to be used to measure any range of temperature easily and accurately, which is of great help in many industrial companies. Though this device is a combination of two metals, the types of combinations keep changing varying on the range of temperature that has to be measured. So thermocouple can be found with different combination of metals for different types of uses in different areas. This is also used in electronic instruments to get accurate measurements of the temperature. This device produces current without any external supply of power, which might be useful in certain areas of science and technology to develop few things through the current.
