Introduction
Temperature sensors are devices that measure temperatures within a certain range and convert the measured temperature values into electrical signals which can be read and understood by the controlling computer systems. Generally, temperature sensors can be categorized into three types: thermistors, thermocouples and RTDs (Resistance Temperature Detector). RTDs (Resistance Temperature Detector) are one of the most popular temperature measurement devices and the most accurate and reliable.What is RTD?
As the name suggests, RTD is a resistance temperature detector that uses the resistance of materials to measure temperatures. In an RTD, a conducting metal material, such as copper or platinum, is used as the sensing element and when the temperature increases, its resistance will increase accordingly. The RTD is connected to an electronic circuit which is used to measure the resistance and hence the temperature.32208191 Application Field and Working Principle
The 32208191 RTDs are widely used in the industrial process control, to measure temperatures within a range of -50 to 200°C. It is designed to have a resistance of 100Ω and an accuracy of better than ±0.5°C. It is also known as “PT100” as platinum is used as its sensing element. The working principle of the 32208191 RTD is based on the principle of electrical resistance. The resistance of a conducting material increases as its temperature increases. The electronic circuit connected to the RTD will measure the electrical resistance change over the temperature range.Advantages of RTD
RTDs are known as one of the most accurate and reliable temperature sensors. They can measure temperatures with high accuracy and can be used over a wide temperature range. RTDs are also relatively small, non-intrusive and have a long life span. Besides, they are also very resistant to vibration and are non-corrosive. This makes them ideal for use in harsh environments.Conclusion
In conclusion, RTDs are one of the most accurate and reliable temperature sensors. The 32208191 RTDs are widely used in the industrial process control due to its high accuracy and resistance to vibrations. It is designed to have a resistance of 100Ω and an accuracy of better than ±0.5°C. Moreover, the working principle behind RTDs is based on the principle of electrical resistance. With its long life span, high accuracy and small size, they are ideal for use in harsh environments.
