RTD TABLE
According to DIN EN 60751
for Class B and Class A
| Resistance vs Temperature Tables According to DIN EN 60751 for Class B and Class A ∝ α = 0.00385 per ITS-90

| t ≥ 0°C : R(t) = R0 · (1 + A · t + B · t 2) With A = 3,9083 · 10-3 °C-1 B = -5,775 · 10-7 °C-2 R0 = 100Ω | t < 0°C : R(t) = R0 · [1 + A · t + B · t 2 + C ·(t - 100°C) · t 3) With A = 3.9083 · 10-3 °C-1 B = -5.775 · 10-7 °C-2 C = -4.183 · 10-12 °C-4 R0 = 100Ω |
| Class B: dt = ±(0.3 + 0.005 · l t l)°C | |
| Class A dt = ±(0.15 + 0.002 · l t l)°C | |
