PRT vs RTD
PRT (Platinum Resistance Thermometer) and RTD (Resistance Temperature Detector) are terms often used interchangeably in the context of temperature sensors. However, there are some distinctions and nuances.
Material:
- PRT: Exclusively uses platinum.
- RTD: Can use platinum, nickel, copper, or other metals.
Accuracy and Stability:
- PRT: High accuracy and stability.
- RTD: Varies by material; platinum RTDs are the most accurate and stable.
Temperature Range:
- PRT: -200°C to 600°C (up to 1000°C for specialised types).
- RTD: Depends on the material, e.g., platinum (similar to PRT), nickel (up to 300°C), copper (up to 150°C).
