Construction of Resistance Temperature Detector
The construction of RTD involves wrapping the resistance wire on mica base. The wire is wrapped in a way to minimize the inductance between each turn of the coil. The whole coil is encased by a stainless steel case in order to protect the wiring. The ending of the wire terminate into leads
Usually the material that are employed to make RTDs should have positive temperature coefficient meaning their resistance should rise with increase in temperature. This means that metals that show linear characteristics should be used some of these materials are Copper, Nickel and Platinum.
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.
