on instrumentation amplifier. Resistance temperature detector (RTD) to detect the temperature change, the temperature change into an electrical signal input XTR101, XTR101 converted into the 4 ~ 20mA current output, through the twisted-pair transmission by RCV420 reception, and then converted into 4 ~ 20mA current voltage signal, amplified to the isolation amplifier ISO122P, after the ISO122P isolation amplifier output 0 ~ 5V voltage.
