Advantages of an RTD
Let us now some advantages of RTDs
- Resistance temperature detectors have high intrinsic accuracy. This means that their electric resistance varies predictably in a range of temperature eliminating any cause of potential error. For example Pt used in RTDs is known for its stable and repeatable characteristics.
- It is known that the metals used in RTDs show linear nature i.e. the variation in their resistance values follows a linear curve with respect to the temperature values. This is useful for predicting any future values.
- Due to high accuracy, RTDs are suitable for precise measurements. It means that the values predicted by RTDs are almost very closely related giving precise results.
- RTDs can be made in any configuration which makes it easier to design an RTD . There is no rule on the shape of RTDs or whether they should be shielded or not.
- They also provide the feature of temperature averaging which is not seen in case of thermocouples and thermistor.
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.
