Measuring temperatures in an environment that humans aren't able to go in has always been a problem. With new technologies and new materials being produced other methods of measuring these temperatures was needed. This is where the thermocouple comes in. The most common of these is the Type K thermocouple.
Thermocouples are used in many industries, such as Power generation, oil and gas and even in everyday appliances such as stoves and toasters. No matter what industry it is a thermocouple will be used. Thermocouples are a sensor comprising of two legs made of different wire. One end of these wires are connected together to form a junction were the temperatures is measured from.
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.
Common uses for these devices are found in almost any industry. Scientific research, gas and oil producers and even a simple oven in the home use these devices. They are even used in the nuclear applications were humans can't go at all. From industrial use such as furnaces to a simple hand held device with a probe. The use of these devices will always be needed to monitor and measure temperatures.
The wires used in these couples are made from noble metals which can react to heat changes very quickly. The k type couple is the most common of these because of their accuracy, reliability and wide temperate range. This couple is used very often in nuclear application due to its radiation hardness and it can with stand continuous temperatures of up to 2000 degrees Fahrenheit. These couples are not only used for extreme heat conditions, they can also be used for extremely cold conditions.
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.
The diameter of the wires influences the response time of the joint. The smaller the wire the quicker the temperature can be measured, but a trade off on this is the temperature range it can handle. The thicker it is the more temperature in can handle but is very slow to respond to the changes.
These couples can be attached in a permanent manner or by attaching it to a hand held probe. The hand held types are for lower levels of heat. These types tend to be shield from corrosive environments as to prolong the life of the probe. From very large to extremely same couples no matter what the application the actual thermocouple will remain the most popular in any industry.
