Why PT100

Each type of temperature sensor has a particular set of conditions for which it is best suited. RTDs, in particular Pt100, offer several advantages:

A wide temperature range with only one sensor

A wide temperature range (approximately -200 to +600°C) with only one sensor.

Good accuracy

With a temperature range up to +600掳C, RTDs can be used in all but the highest-temperature industrial processes.

Good interchangeability

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.

Long-term stability

However, these materials are not commonly used since they have lower temperature capabilities and are not as stable or repeatable as platinum.
