During the heat measurement of thermal resistance, the subsequent wire can be called the platinum transmission line. The compensation wire is the extension of the thermocouple puppet. How long the platinum charging line is used, which mainly depends on the wiring method you use. It can ensure that the 3 leading resistance is equal. Theoretically, the length can be increased according to the customer's needs, but it has a lot to do with the input impedance of the temperature controller (the outer diameter that can increase the outer diameter to reduce the lead resistance), so the accuracy requirements (A -level) Top 10m, (B -level) 20M, try to use thick lead.
