The type J thermocouple is a simple but accurate widely used device for measuring temperature accurately. Usually, it consists of two different wires of dissimilar metals joined at one end commonly known as the hot or the measuring junction. There is another end where the wires are not joined. This end has a link with the signal conditioning circuitry traces.
The potential difference or the voltage produced in the system depends on some attributes, which include the state of the reference junction and temperature intensity. However, without the knowledge of the exact amount of the reference temperature, it will be difficult to come up with accurate absolute temperature readings. The whole of this procedure is known as reference junction compensation.
The use of this device has become a cost effective standard of measuring temperature in a wide range with a sensible level of accuracy. The device is used in various applications with up to +2500 degree centigrade in aircraft engines, water heaters, boilers and ovens. Because it guarantees an accurate measure of absolute temperature, you are sure of getting the right results in your application area.
One of the features that make this device unique is its rapid response ability. This device is small and in addition, has a thermal conductivity of a lower level. This makes it easy for them t have a quick response to temperature changes, especially in areas where there is an exposure of the sensing junction. The device can respond to hotness or hotness of a place within a short time.
The device is known for its robust condition. It has a rugged shaped and this gives it the power to become immune to continuous vibrations and rigorous shock. It is therefore a device best for use in temperature reading even in the most hostile environment on the surface of the earth.
The other advantage of this device is that it has the ability to measure a wider range of absolute temperature. For instance, the temperature range for most devices like jet engines can be measured using this device. The device has the ability to measure temperature of up to +2500 degree centigrade, although this depends on the metal used.
However, it not always an easy task to transform the potential difference that the thermocouple generates into an accurate temperature reading. There are so many reasons behind this. Some of these include the case that the voltage is usually small, the thermocouple may at times pose grounding problems, there is a dire need for reference junction and the relationship between the potential difference and the temperature to be measured is not linear.
Type J thermocouple and the rest in general have consists of signal conditions that are more complex than other systems used in taking temperature readings. The span taken in creating and checking errors on the signal conditions may also vary and at time may be lengthy thus causing delay in the production and marketing of these devices. If an error occurs on these signals, the system may actually fail to work or perform with a minimal level of accuracy.
