Res pt
Type Function: REAL¶
| Input T | REAL (temperature in °C) |
| R0 | REAL (resistance at 0° C) |
| Output | REAL (resistance) |
| RES_PT calculates the resistance of a PT resistance sensor from the input values T (temperature in °C) and R0 (resistance at 0°C). | |
| The calculation is done using the formula | |
| for temperatures > 0 °C | |
| RES_PT = R0 * (1 + AT + BT²) | |
| and for temperatures below 0 ° C | |
| RES_PT = R0 * (1 + AT + BT² + C(T-100)T³ | |
| A = 3.90802E-3 | |
| B = -5.80195E-7 | |
| C = -427350E-12 | |
| The calculation is suitable for temperatures from -200.. +850°C. |
