Learn more about the accuracy of temperature measurement using RTDs (Resistance Temperature Detectors). This video explains the international standard IEC 60751, which defines three accuracy classes for PT100 sensors: Class B, Class A, and Class AA. Class B has a tolerance of ±0.75°C at 100°C (±1.35°F at 212°F) , while Class A and Class AA offer higher accuracies of ±0.4°C (±0.72°F) and ±0.2°C (±0.36°F), respectively. Another important factor influencing RTD accuracy is the wiring configuration. A four-wire connection is recommended for highest accuracy, as it compensates for line resistance variations.
In general: proper planning is crucial for accurate RTD measurements!
