FAQ
What’s RTD?
An RTD(Resistance Thermometer Detectors) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. Its main features are high precision and stable performance.
What is the difference between a thermocouple and RTD?
In general, a thermocouple can measure a larger range of temperatures. The measuring range lies between −180 °C to 2,320 °C. On the other hand, RTD is more suited to measure lower ranges of temperature. The measuring range of an RTD lies between -200°C to 500 °C. On the other hand, thermocouples are cheaper, more durable, while RTDs produce better and more reliable measurements.
What difference between Pt100 and Pt1000?
The main difference between Pt100s and Pt1000s is usually 0⁰C, which is the obvious number in the name: Pt100 is 100Ω⁰C at 0 and Pt1000 is 1000Ω⁰C, compared to PT100, PT1000 is more sensitive and accurate for small temperature changes, it will result in a larger resistance change.
