what is the use of impulse line in AFBC boiler , WHY WE
CONNECT IMPULSE LINE TO TRANSMITTER , DRFT GAUGE ETC ????????
Answers were Sorted based on User's Feedback
transmitter has a sensor which has a temperature withstand
around 150c but actually steam line is more than 500c this
txt. cant withstand so a condensate pot is available in txt.
impulse line are connected to that pot through that a cold
dm water is poured and txt. taken in line when steam comes
it gets condenses in that pot itself so sensor will not be
affected

as the impulse line are connected to that pot through that a
cold
water is poured . taken in line when steam comes
it gets condenses in that pot itself so sensor will not be
affected
hence
the use of impulse line in AFBC boiler , WHY WE
CONNECT IMPULSE LINE TO TRANSMITTER , DRFT GAUGE ETC are
done

Answer / s vedpathak
Using DP Tx, we measure differential pressure to measure
level,flow.To measure this pressure i.e. the HP & LP
pressure , impulse tubes are required to be connected
across the capsule of DP Tx.

Answer / amit patel
In case of Level measurement boiler drum , if we are not
used impluse tube then steam directly contact with
transmitter diapharm which getting damaged beacuse of TX
diapharm can withstand maximum temp around 150 degree
centigrade. So when steam flow carrying in impluse tube
then its temp comes down due to atm temp and becomes
condensate water.

I am pujita completed Electronics and Instrumentation Engineering.As a fresher i am going to attend the interviews.Could anybody guide the topics/questions covered mostly in interviews.
Dear all... I have 1 0-400 duplex type RTD, I connected the A side to the temperature indicator and B side to the PLC panel, but when I have observed then found that The PLC side temp has the variation. and it was distub to other RTD temp also. so what can I do.
