PT100 temperature sensor transmission distance of the note

Pt100 temperature sensor, it is only a resistor, resistance changes with the temperature change. 2, use Pt100 directly in PLC hundred meters away, certainly great error. 3, suggest supporting PT100 temperature sensor transmitter, output 4 - 20 ma current ( Estimate that you use? ) 4, if the current transmission, more than 100 meters, there will be no problem because it is a current output ( Current size only related with the temperature, has nothing to do with the outer conductor resistance size) , so there is no current loss. 5, is too long can introduce interference, lead measurements jump, if digital display this kind of situation, it is recommended to use shielded cable and filtering processing in PLC.
