TAT Calculation

ADR internal calculations:

Just as I mentioned before:



TAT calculation is back to Elementary School:




The Calender-Van Dusen equation for a 500ohm platinum sensing element is used.
  • RT/RO = TAT + α[TAT - δ(TAT/100-1)(TAT/100) - β(TAT/100 –1)(TAT/100) 3]
where
  • TAT = temperature in °C
  • RT = resistance at temperature "T"
  • RO = resistance at 0 °C (500 ohms)
  • α = .003832
  • δ = 1.81
  • β = 0.0 for T > 0.0° C and 0.1 for T<0.0 °C
