Obergrenze (Messabweichung < ± 2 K)
Upper limit (Measuring deviation < ±2 K)
Lower limit (Measuring deviation < ±2 K)
Lower limit (Measuring deviation < ±3 K)
Examples:
If the gas temperature is +30 °C and the dew point is -20 °C, an accuracy of < ±2 K is
■
achieved (since Tgas - Td < 60 K).
If the gas temperature is +40 °C and the dew point is -30 °C, the accuracy of < ±3 K
■
is achieved (since Tgas - Td < 80 K)
