Type j thermocouple is a kind of thermometer that measures temperature differences. The device is made of two wires of different materials that are joined at both ends. One end has a low fixed temperature while the other is used to show the temperature to be measured.The wires are connected to a voltmeter to record any data regarding the changes. Therefore, this instrument can show any variations in temperature.
These devices are of different types, hence their different names. They are named using letters ranging from J to S. However, K is very dominant since it is used widely in many areas. Environments where they are used include; dry environments, water, gases, and mild chemical solutions. They have several advantages and disadvantages. Some of their merits and demerits are discussed herein below.
This type is usually made from nickel metal which forms almost ninety percent of the total material in them. Since it is mixed with other materials like Chromium and Aluminum, it is said to have two main components namely; Chrome and Alum. These two form the junctions; one which has a fixed low temperature while the other is the one which measures the temperature variation. The junction measuring the difference is the one that has a voltmeter connection to show the change caused.
People always buy materials based on their cost. The lower the cost, the more the number of customers because this will boost their purchasing power. This is the same thing with this thermometer. It is inexpensive unlike many others in the market making people to go for it. Lower cost does not mean that it has compromised performance since it works perfectly well.
The most important of all is its accuracy and reliability. The device is very accurate unlike the others available in the market. Errors common to this kind of devices is reduced to a great extent. This makes most people go for it because they are sure they will get good results. This is actually the point why it is so much in demand of all the types available. Above all the error-free factor makes it so reliable.
They can be able to work with even the highest degree of temperature unlike other devices. The temperature can range from negative hundred degrees to one thousand two hundred degrees Celsius. This makes it better than many others that only work in a limited temperature range. They are covered almost all the time with an insulating material to avoid any effects. This insulation is however not necessary in oxidizing environments.
Due to the wide temperature range that may go up to one thousand three hundred degrees Fahrenheit, there is need to insulate this device. This is required especially in oxidizing environments, and materials like metal tubes can be used. However, insulation or protection covers are not necessary in an oxidizing environment like in an electric furnace.
The type j thermocouple has demerits that affect its operations and demand. Those who argue against it say that it does not suit a reducing atmosphere. It also has an aging electromotive force unlike some other materials that doe really best. Since it has more benefits than disadvantages, it remains to be in demand than any other.
