Kg/cm2 by a Pressure transmitter of range 0 to 10

Going by standards, 20 mA of first transmitter will read 25 kg/cm2 pressure, while same reading for second transmitter will be 10 kg/cm2. So at same pressure, both transmitters will send different current signals. So calibration at the DCS end will be needed.
