What Is a Platinum Resistance Temperature Detector?
A platinum resistance temperature detector (PRTD) is a highly accurate temperature sensor used for temperature measurement, employing platinum material.
Constructed using platinum wire, it exhibits an increase in electrical resistance as temperature rises. This characteristic is utilized for temperature measurement. One of the main advantages of PRTDs is their high accuracy. Platinum is highly sensitive to temperature changes, enabling extremely precise temperature measurements. Additionally, PRTDs can be used over a wide temperature range, typically operating from -200°C to +1000°C.
Compared to other temperature sensors, PRTDs demonstrate high stability over extended periods of measurement and exhibit a rapid response to temperature changes.
