The instrumentation cables are meant for making the connection between the RTD and the measuring device (resistance loop) or between the transmitter and the measuring device (mA) loop.
In both cases, the idea is to keep the resistance of the cable as small as possible to reduce the measurement error or to allow the transmitter to draw its maximum current in the case of 4-20 mA loops. Therefore, the cross section of the cable should be increased when the cable length increases.
