Resistance Temperature Detector
What are other temperature measurement devices?
Some other devices that can be used for measurement of temperature indirectly are thermocouple which measures temperature by converting it to voltage and thermistor which measures temperature by showing non-linear variation.
What is the temperature range in which RTD gives accurate results?
RTDs have a small range where they give accurate results. This range is 260-8500C
What are some materials that are used to makes RTDs?
Some of the metals that make up RTDs are platinum, nickel and copper. Materials that make up RTDs must be conductive and must show linear change in resistance with temperature which is seen in case of these metals.
Resistance Temperature Detector or RTD
In the electronics industry, we often need to deal with measuring certain quantities with precision and accuracy. One such quantity is temperature. There are different methods that can be used for measuring temperature depending on the operation range, sensitivity, frequency response, ruggedness, and other electrical parameters. In this article we will study what is an RTD, and how it works. We will also study the characteristics of an RTD.
In addition to that, we will study the advantages and disadvantages of an RTD. To study the real-life use of RTDs, we will study the applications of an RTD. In the end, some solved examples and some practice questions are provided for a better understanding of concepts. The article concludes with a summary in the end and some frequently asked questions.
