|why does mA signal preferred for signal transmission?
|As you are fresher in Instrumentation & control
engineer.Then why should I select you?
|In your own words, would you expect an ultrasonic level
device to work better in a pressure vessel with a high
pressure or a strong vacuum, and why?
|In E&I diagram what is the meaning of rectangular box and circular box
|why do we use 4-20mA as o/p and why don't use 0-20mA or 5-
I am MD.zafar eqbal. I have taken this id
from allinterwiev .com
I have qustion if you dont mind.
1.what is the maximum operating
temprature in instrumentation.
2. I want know about viberation i mean
wahat types of sensor used in viberation
And what types of trabsmitter used.and
hiw to control it and wher is used of
viberation transmitter and finally how to
control it and what types of fault come.
Sorry for disturbing you. I know you have
no reason for help me. Because you dont

|what is corrective maintenance , explain with difination
|what is meant by nuclear power plant?
|Air pressure in a pressure vessel can rise or fall at up to 2.5kpa/s.The pressure is
sampled every 0.5 seconds.If range of the the pressure indication is 0 to 1500
kPa, what is the max value of the error due to sampling in % of Span
|A pressure transmitter with a range of 0-100 bar.The
accuracy of the instrument is 1% of upper range value?
The pressure indicating transmitter is showing the system
pressure is 50 bar.
b. When you include the error, what is the minimum possible
pressure in our fuel gas system?
i. 49.5 bar
ii. 49 bar
iii. 1 bar
iv. 0.5 bar
We want to change the filter cartridge. We must depressure
the fuel gas system.
c. After we depressure the system in preparation for
maintenance, the transmitter displays a pressure of +0.1
bar. At this time, what is the possible range of pressures
in our fuel system?
i. +0.099 to +0.101 bar
ii. 0 to +0.2 bar
iii. -0.1 to +0.3 bar
iv. -0.9 to +1.1 bar
|why we use 4-20 mA for calibration of the instruments.why
we cant use 0-20 mA?
|Why we use 3-15 psi air for control
