Constant current source   to demonstrate the concept of 4-20 mA    current signal transmitter        

         Change the load resistance ( represents the both series resistance of line and load), output current will remain constant. To adjust current change input VD using pot (represent the sensor)  

        voltage source in  the current  line represent the electromagnetic interferences and demonstrate no effect on the current if changed + or - (slightly not affecting to saturate the op amp)
