If you’re looking for a reliable and accurate way to measure temperature, you can’t go wrong with a resistance temperature detector, or RTD. RTD elements are made of a material with a known resistance that changes with temperature, making them ideal for precision measurement. It is nowadays considered as a core temperature sensing technology widely used in temperature sensor assemblies and RTD probes. RTDs are generally made from different materials such as copper, nickel, platinum, and gold.
There are many different RTD element designs, but they all work on the same principle. As the temperature of the element changes, so does its resistance. By measuring the resistance, you can accurately determine the temperature of the element. RTD elements are used in a variety of applications, from industrial process control to consumer electronics, and HVAC systems. They’re well-suited for temperature measurement because they’re highly accurate and stable over a wide range of temperatures.
Importance of Thin Film RTD Element Design!
There are many factors to consider when designing an RTD element, such as material selection, resistance value, size, wiring and connection type.
- The most important factor in RTD element design is the material selection. The material must have a high resistivity in order to accurately measure temperature. The most common materials used for RTDs are platinum, nickel and copper.
- Platinum is the most expensive material, but it is also the most accurate as they provide the best linear resistance change. Platinum RTDs can measure temperatures up to 800 degrees Celsius.
- Nickel is less accurate than platinum, but it is cheaper and can measure temperatures up to 500 degrees Celsius.
- Copper is the least accurate of the three materials, but it is the least expensive and can measure temperatures up to 300 degrees Celsius.
- The resistance value is important because it determines the accuracy of the temperature measurement. When selecting the material for an RTD element, it is important to consider the accuracy requirements of the application. For applications that require high accuracy, such as HVAC or automotive, platinum is the best choice.
- The size and wiring of the RTD element also need to be considered, as they can impact the accuracy of the temperature measurement.
