A thermocouple probe is the measuring method of choice being used by at least 60 percent of U.S. industrial technicians and engineers. There are some good reasons for choosing a thermocouple probe over other temperature sensors. One main reason is that the situation demands a sensor that can handle lots of stress. Another is that you may be
dealing with extremely high temperatures that may exceed the abilities of other sensors.
A thermocouple robe may also be chosen because it is rugged enough to withstand an industrial environment. They are inexpensive, very responsive and they provide the widest temperature range when compared with contact sensors. You will often find a thermocouple used in heating, ventilation and air conditioning products because they are very flexible and can be developed out of almost any material needed to fit the product.
There is a direct relationship between a thermocouple probe and the heat and electrical energy contained within electrical wires (thermocouple wires). The more kenetic energy that an atom has, the faster it moves around and vibrates. The atoms that have the most kenetic energy are located on the hot end of the wire. The nucleus of an atom is contained within the temperature difference between the hot and clod ends of the wire. The size of a wire has no effect on the voltage that is created.
A thermocouple probe can "tip" sensitive. They have the ability to measure temperature on a small area. The output is nonlinear. This means that the thermocouple probe needs external linearization from cold-junction compensation to make sure it provides the most accurate temperatures.
When creating a hot junction it is important to realize that the materials that you select will determine the type of thermocouple probe that you wind up with. The materials you use to make a thermocouple probe useful for certain applications depend heavily on the temperature range and environment. The four thermocouple probes that are used 99 percent of the time and are easily identified by the letters: K, J. T and E
A thermocouple probe is ideal for corrosive, industrial or plant environments where constantly fluctuating temperatures are the norm. A thermocouple device can function quite accurately in situations where temperature changes are changing within 30 seconds or less. The durability of this thermal measuring device in such a rugged, temperature changing setting depends on the sheath which is designed to give the thermocouple probe the durability required to perform as needed.

The engineering team at DeVale have been very helpful with their guidance and support through our product design stage. We have not seen that level of support from any company in their industry.
