How does one measure temperatures that are too hot for humans to be near? A traditional thermometer would be used for temperatures of around 200 degrees Fahrenheit and would destroy them if exposed to anything higher. Electronic thermometers can handle heat inside a computer but not a furnace at over 2000 degrees. The only option would be to use a type K thermocouple.
When the conductors are exposed to heat or cold they produce a voltage. This voltage difference between the two conductors can be used to determine the temperature. The materials used to produce these conductors have a predictable and repeatable voltage gain or drop according to temperatures they are exposed to.
By referencing the change in voltage produced by these wires the temperature can be determined. There are factors that can affect the performance of these wires, such as diameter the environment it will be put in and also if it needs to be shielded from corrosive elements. Shielding will need to be taken into account when measuring the changes in voltage as the conductors are not exposed directly to the elements. Luckily the monitoring device can compensate for this.
A wide range of temperatures can be measured using these devices and some factors can influence the measurement. One of these is the environment they are to be used in. If it is a chemically harsh atmosphere the couple can erode and the life span of it can be drastically reduced. By shielding it by means of a sheath it can be protected and thus its life span extended.
They are built for reliability and due to the unique characteristics they can be used in high vibration environments and chemically harsh atmospheres. The couple itself is low cost but the instrument used to interpret the voltage variance can be costly. On the other hand they can be calibrated to the different types of couples used, thus they can improve the precision and accuracy of the measured voltage.
Type K is the most common general purpose couple. It has a more average sensitivity compared to other types and is inexpensive to produce. It is used in a relatively wide variety of probes and can measure from extreme negative temperatures to extremely high temperatures. One of the conducting materials used in this type of conductor is magnetic and can be susceptible to deviation I n the output voltage.
To differentiate between the different types available, a color combination of the wire sheathing is used. For the type K it will be yellow for positive and red for negative. If the couple is corroded it can lead to incorrect measurements and could give a low reading on the output voltage and may even fail altogether. This often occurs when the couple corrodes due to chemicals and moisture.
Thermocouples have made a large impact on the steel production industry. By adding various metals into a mixture at varying temperatures new alloys can be created. The only way to check if the correct temperature has been reached before adding the next metal is through the use of these couples. The thermocouple itself will be the most likely one to be used for this application.
