A resistance temperature detector (RTD) sensor contains a resistor that measures the temperature by tracking the change in resistance as its temprature changes.
RTD sensors are known for their high stability and accuracy, which makes them best choise for applications where precise temperature measurement is needed.
Resistance temperature detector sensors are made of materials like platinum, nikel or copper.
RTD sensors requires more complex circuit to read the resistance and convert it to the temperature value.
RTD sensors are more expensive as campare to standard temperature sensor.
RTDs can be used in a wide temperature range, from -200°C to over 1000°C, depending on the material and construction of the sensor.
RTDs are commonly used in industrial applications, such as in chemical plants, power plants, and food processing, as well as in laboratory and scientific applications.
The temperature measurement range of an RTD sensor depends on the material used. Like, platinum RTDs can measure temperatures from -200°C to over 1000°C, while copper RTDs are limited to temperatures below 150°C.
RTDs can exhibit a self-heating effect due to the current flowing through the sensor, which can lead to inaccuracies in the temperature measurement if not properly compensated for.
