Temperature is measured using different methods depending on the environment. RTD or Resistance temperature device is based on the scientific fact that changing the temperature of a conductor will affect its resistance. The flow of electric current as a result of heating or cooling is used in calibrating the devices. The principle of correlation is used with a great deal of standardization.
The most common metal for this purpose is platinum. It is widely used because it displays consistency over a wide range. The level of accuracy is incredible which makes it reliable for industrial processes. It has an incredible sensitivity that makes it preferable over the others.
Industrial processes are very specific when dealing with heat. This raises the need for high sensitivity and faster response. The metals used in this case are carefully selected to ensure that their response time is minimized. It gives a signal to control and monitoring units to take action before the outcome is compromised.
The industries that benefit from this technology include manufacturers of appliances, automotive industry, control sections and HVAC. Production plants with measuring and testing units need to constantly monitor the temperatures. A higher level of consistency and accuracy is required to achieve desired results. Common metals for this purpose include copper, nickel and platinum.
The best element for use as a conductor must display consistency over a wide temperature range. Sensitivity to slight increment or reduction in the amount of heat is also important. The sensitivity of such processes as extraction means that the highest possible accuracy degree must be achieved. This prevents scenarios where the outcomes are compromised.
There are limitations to the use of these devices. They arise out of their behavior when exposed to heat in different circumstances. RTDs are not used where the heat levels go beyond 660 degrees Celsius. Platinum is easily and readily contaminated by impurities at such conditions. These impurities come from the sheath of such thermometers.
Impurities found at boundaries and changing temperatures have a significant effect on the behavior of conductors in RTDs. This has been clearly noted when it is below 270 degrees or 3 Kelvin. The elements used have very few phonons which explains their behavior. This affects their sensitivity to slight changes in temperature.
RTDs face the challenge of maintaining accuracy when making conversions for the purpose of calibration. There is a delicate relationship between temperature and resistance in conductors. The interference of other properties affects the outcome which could lead to erroneous results and compromise industrial processes.
Prolonged thermal exposure is likely to affect the properties of conductors used. There is a possibility of recording different measurements over a cycle of heat and cold. This behavior is referred to as hysteresis. It has been observed in different elements and threatens the use of RTDs in sensitive and long running industrial processes.
Interference from the sheath and impurities on the device cause loss of heat. This affects the accuracy of such devices. There is a possibility of current flowing through the conductor from other sources. Other factors that affect accuracy include the number of wires used as conductors. The response time for these devices is not satisfactory in some instances.
