RTD Choice

RTD Sensor

Why use an RTD instead of a thermocouple or thermistor sensor?

Each type of temperature sensor has a particular set of conditions for which it is best suited. RTDs offer several advantages:
• A wide temperature range (-50 to 500°C for
thin-film and -200 to 850°C for wire-wound)
• Good accuracy (better than thermocouples)
• Good interchangeability
• Long-term stability
With a temperature range up to 850°C, RTDs can be used in all but the highest-temperature industrial
processes. When made using metals such as platinum, they are very stable and are not affected by corrosion or oxidation.
Other materials such as nickel, copper, and nickel-iron alloy have also been used for RTDs. However, these
materials are not commonly used since they have lower temperature capabilities and are not as stable or repeatable as platinum.
