can we replace a pressure transmitter of range 0 to 25
Kg/cm2 by a Pressure transmitter of range 0 to 10
Kg/cm2 ?.. Will it affect 4 to 20 mA output signal which we
will feed to the PLC.

Its not possible by answering without knowing the application
But in both the cases v can get the 4-20mA output
In case if the o/p doesnt goes beyond 10kg then v can replace and the o/p side of tx shud be calibrated before installing and the changes shud be entered on plc.
In another case if the user wants better accuracy he may b using 0-25kg/cm2 tx eventhough the internal pressure is b/w 0-10kg/cm2
