Answer / hiren

dp transmitter is used to measure DP but the pressure
applied across diaphargm is actual process pressure. so if
any one get fail then transmitter should not fail.

Answer / komal

Static Pressure is done on DP transmitter because of check
if the transmitter can withstand the static pressure acting
due to Line Pressure when in process. The Line pressure can
be 100 bar but the DP that is measured on transmiter can be
as small as 1000 MM H2O.

Answer / mhakave rajesh

it's span of measurement may be less eg 0- 5 bar,but
pressure acting on single side either of hp or lp (i.e.
process side pressure) may be high, so to check zero of tx
at such operating pressure it is........ so and so.

Answer / b.s.m.raju

This is DP transmeter high static preesure of 100 bar.
Small range will be used 10 mbar. but span range very low
Accuracy will be poor.

While preparing the graphic diagrams trend display, 3 types of trends are prepared by Yokogawa system vender. These are for process variable, manipulated variable & set point variable. Why these 3 trends are required? Explain the purpose of these 3 trends.

Foe selecting control valve if i have the min,normal & max data of flow rate,inlet pressure& outlet pressure,inlet tem.&density than how can i assure that these data are correct,pl. let me know if therew there is any method to check it.& also how we assure that the Cv we get from this data is suitable for valve for controlling require flow.

In control valve there are two type of valve seat we can use metal to metal seat & soft seat.On this valve seat i have following doubt. 1)I have never seen practically the internal assembly of valve so my doubt is that basically weather the seat is soft seat or metal its basic MOC is same as valve body(SS or CS) only in soft seat we are using PTFE ring & place on valve seat & in metal this PTFE ring is not threr am i correct??????? 2)what are the common general rule for using metal to metal seat & soft seat,means its depend on process parameter like liquid,gas, steam & on valve leakage class.
