Temperature can be gauged and regulated using electric equipment known as a thermocouple. There are many different kinds of thermocouple types. They are made from two kinds of metal conductors which when joined together produce emf at the junction where they are in contact. They are used by kilns, diesel engines, gas turbines, industrial and exhaust, and science applications to measure and change temperature gradient to electricity. Thermocouples are used where most temperature gauges cannot be used due to their ability to be applied in high temperatures conditions since they have a wide temperature range.
They can also be used for making heat to electrical energy transducer coolers used for cooling things on the go as a result of the ability to apply cooling directly to components that might on overheat. They are also used in generating power and making bolometers.
Thermocouples are grouped into different classes. Those whose metal conductors have platinum which is known to be rare metals are known as the crust of the upper class. This class is divided further into smaller classes. Thermocouples that have conductors which are fabricated using platinum and the other made of platinum rhodium alloy are type R and type S. For temperatures that varies from 1600 to 2640 degrees Fahrenheit type R thermocouples are used while type S thermocouples are applied in higher temperature between 1800 to 2640 degrees Fahrenheit.
Type B is thermocouple which is regarded to be more constant and less sensitive. Having a higher brown crust area category. One of the conductors has 6 % rhodium steel and 94 % platinum on the other hand the other conductor has 30 % rhodium steel and 70 % platinum measuring between 1371 degrees C and 1704.44 degrees C. The class of thermocouple discussed in here, has been found out to be less sensitive but very stable. This is according to the research findings of many physicists and scientists who have used it.
The Home Body Class thermocouples transmit electricity using non rare materials. The C, E, J and K classes are the subcategories in the Home Body Class . Where in kind C one conductor has 74 % tungsten and 26 % rhenium the other having 95 % tungsten and 5 % rhenium.
Thermocouples that use conductors made from refractory metals are in the rarefied class. These type are used in different applications. Mostly used in nuclear power plants because of their ability to highly resist wear and hear.
The Exotic class of these transducers have a very specified nature. A required percentile of metals which are rare are applied in definite applications and environments especially in experiments which are advanced. These experiments are normally conducted in research institutions, colleges, and universities. Adequate care should be taken when handling thermocouples to prevent improper readings. Accurate marking of graduations of this transducer should be made to standardize it.
Thermocouples are naturally considered to have a high level of complexity hence are highly likely to have errors when used because it is difficult to operate. Both ends of the two dissimilar metals used record different voltage levels as a result of temperature change. The thermocouple types used distinguishes different marginal error is recorded since different classes of electronic compensation are used at the cold junctions.
