Connect two plc system with one pressure transmitter

Is it possible to connect a pressure sensor with two analog inputs port 4-20 mA , one connected to a plc s7-400 and the other is plc s7-300 in one loop and is the measurement will be correct compared with one plc? And is this method is useless and correct method?

Hello,

Yes i think you can use it with Isolating amplifiers with splitter function

I mean without using isolation devices 

Connect two Ai current port series in on loop with one pressure transmitter
