What is another name for thermocouple?
thermoelectric thermometer
Thermocouple, also called thermal junction, thermoelectric thermometer, or thermel, a temperature-measuring device consisting of two wires of different metals joined at each end.
What is thermocouple explain?
A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature.
How would you best describe a thermocouple?
A thermocouple is a sensor that measures temperature. It consists of two different types of metals, joined together at one end. When the junction of the two metals is heated or cooled, a voltage is created that can be correlated back to the temperature. Thermocouples are commonly used in a wide range of applications.
What are the two types of thermocouple?
Type J, K, T, & E are “Base Metal” thermocouples, the most common types of thermocouples. Type R, S, and B thermocouples are “Noble Metal” thermocouples, which are used in high temperature applications (see thermocouple temperature ranges for details).
What are the different types of thermocouples used for?
A wide range of different thermocouples are available for different applications based on metals with high conductivity, such as iron, nickel , copper, chromium, aluminum , platinum, rhodium and their alloys.
What is the relationship between temperature and current in a thermocouple?
Any current in a thermocouple circuit is a function of circuit resistance in opposition to this voltage (I=E/R). In other words, the relationship between temperature and Seebeck voltage is fixed, while the relationship between temperature and current is variable, depending on the total resistance of the circuit.
What’s the difference between Type K and T thermocouples?
The conductor materials used in Type K thermocouples are more chemically inert than Type T (copper) and Type J (Iron). While the output of Type K thermocouples is slightly lower than Types T, J and E, it is higher than its closest competitor (Type N) and has been in use longer. How do I choose between different types?
Why are thermocouples called ” thermos ” in Greek?
What we have here is a pair (couple) of metals that are joined together (coupled) for measuring heat (which, in Greek, was called “thermos”). So that’s why it’s called a thermocouple. What are thermocouples like in practice? All we really care about is one of the two junctions—the one measuring the unknown temperature.
