For Temperature Sensors, What PT100 and PT1000 Stand for
From: Issued date 2019.05.02 Back
Pt100 is the platinum thermistor, and its resistance value will change with the temperature change. The "100" next to PT indicates that its resistance value at 0℃ is 100 Ω, and its resistance value at 100℃ is about 138.5Ω.
Due to the change relations between the temperature and the resistance value of the PT100 thermal resistance, our people have taken advantage of such characteristic of it, invented and produced PT100 thermal resistance temperature sensor. The temperature collection range can be -200℃～+850℃.
Pt1000 is the platinum thermistor, and its resistance value is proportional to the temperature change; the change relations between the resistance value and the temperature of PT1000: When the temperature of PT1000 is 0℃, its resistance value is 1000Ω, and when the temperature is 100℃, its resistance value is about 1385.005Ω. Its industrial principle: The resistance value will increase at a constant speed as the temperature goes up.
Differences between PT100 and PT1000
1. The resistance difference at 0℃: 100Ω for PT100, while 1000Ω for PT1000;
2. The temperature range difference: -200~850℃ for PT100, while -50~300℃ for PT1000;
3. The indexing number of PT1000 is 10 times bigger than that of PT100, and the measurement accuracy is higher;
