AD10T2 100-OHM PLATINUM RTD
A 100-ohm platinum RTD (reference DIN 43 760, alpha = 0.00385) must be used with the AD10T2 for the
following conversion algorithms to be accurate.
VALUE% Formula
Temp Range
(°C)
< 2111
A = (VALUE% * 0.09474182) - 50
TEMP = A + (0.000156 * A
2
) - (0.0156 * A) - 1.11
-50 to 150
2111 < 4094
A = (VALUE% - 2111) * 0.1008065 - 100
TEMP = A + (0.000156 * A
2
) + 248.45
150 to 350
4095 < 6218
A = (VALUE% - 4095) * 0.1082863 - 115
TEMP = A + (0.00017 * A
2
) + 462.76
350 to 580
> 6218
A = (VALUE% - 6219) * 0.118525 - 13
TEMP = A + (0.000188 * A
2
) + 711.565
580 to 850
Accurate to ±0.15°C from -50°C to 580°C, to ±0.2°C from 580°C to 850°C.
