Answer / ruchita

Yes it will affect the 4-20 mA signal. say for example if we are using PT of rsnge 0 to 25 bar bt internally we use only 0 to 10 bar range den it can be replaced otherwise not

Answer / yashwant

yes, only make sure the pressure will never rise beyond 10 I
think its design for 25 in safety condition. if u wish O/p in
0-10 you can scale 4-20 ma as 0-10 at plc, no need to change
tx.

Answer / vijay

it depend upon ur range in the application for example
piston producing pressure within 10kg/cm2 then u can use it
by change program in the plc otherwise u cant

Answer / vinod hepat

Yes first of all note whether range is suitable for ur
application.replace transmitter & accordingly change the
range in DCS.

Answer / madhav kamble

Yes. you can replace the pressure transmitter form 0-25 to
0-10. it willnot change the 4-20 mA which we will send to
the PLC but you to change the calibration at PLC for New
0-10 transmitter.

Answer / govind singh

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.

Answer / imran

first of all you need permission to replace pressure tx
from operation instead 0-25 by swaping 0-10cause it will
effect process & may you r going to upset process other
point of view by technical you need to configure it & it
will give you output vice varsa

Answer / dinesh kumar

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

Answer / trideep

If range is in b/w 0-10 kg/cm2 or with in that, then it will do..
