Is a compensation wire needed for a PT100 platinum resistor?
A three-wire system is generally used, with 1-square copper wire, and no compensation wire is needed!
One of the wires in the three-wire connection serves as a compensation wire
Only thermocouples require compensation wires; thermal resistors do not need them, haha
All use a three-wire system; no compensation wires are needed, only for thermocouples
Thermocouples require compensation wires, while thermal resistors do not. Thermal resistors generally use a three-wire or four-wire system to eliminate the impact of changes in ambient temperature on wire resistance, which could affect measurements.

I agree with what was said on floor 5: it’s not that thermal resistors don’t require a compensation wire; rather, one of the wires in the three-wire system serves as the compensation wire. It’s just that we don’t call it a compensation wire in everyday usage. Everyone is familiar with the compensation wires for thermocouples, but some may not be aware of those for thermal resistors. I also found out not long ago; it was someone from a manufacturer that makes thermoresistors who told me. . Let’s share it.
Thermoresistors do not require compensation wires, while thermocouples do. Thermoresistors use a three-wire system, and temperature compensation is achieved based on the principle of a balanced bridge~~
Generally, three-core copper wire is used, and no compensation wire is needed!
I’ve never heard that thermal resistors require compensation wires; compensation wires are generally used for thermocouples. Thermal resistors are usually connected using a three-wire system, one of which can be considered a compensation wire
No compensation wire is required. The three-wire method is typically used to overcome the impact of line resistance on measurements.
