RTD Calculator (Pt100/Pt1000)
Sensor and value
Tolerance classes (IEC 60751)
Each class is valid only within the temperature range stated by the sensor manufacturer.
Lead resistance
Resistance per conductor
0.000 Ω
2-wire: both conductors add to the sensor. 3-wire compensates equal conductors, 4-wire eliminates them. Copper ρ = 0.0175 Ω·mm²/m at 20 °C.
