Basically Instrumentation deals with measurement and
indication/transmission of physical quantities, which are
used for control and monitoring of plants/equipment. When
the Control and monitoring part is performed without
intervention of human being , it is called automation. For
100% automation system take care of operation of
plant/machinery. But, still humen intervention is required
during start up, shutdown and abnormal condition since
practically 100% automation is not achievable over the
whole life cycle of automation.
INSTRUMENTATION deals with the use of sensors and other
devices in the measurement and transmission of pysical
parameters such as flow,pressure,level,temperature etc from
one point(field) to another(CCR,FAR)for monitoring,control
and safegaurding.The monitoring,control and safegaurding
applications involves the system aspect of instrumentation
while the the field devices and sensors for measurement is
more of electromechanical hardwares.
The integration of the instrumentation hardware and systems
(application) to automatically monitor,control and
safegaurd any manufacturing and production process is what
is called AUTOMATION.
instrumentation deals with the measutemnt and calibration of the instrumnts under measuremnt it helps to achieve the goal of plant being automated
Bcoz automation is the facility which utilizes instrumentation as a key part in its facilitation to achieve the goal of plant automation
Instrumentation is measurement, control and calibration of pressure, flow, temperature, etc which are called physical parameters manually using some instruments. same way using some programming computer softwares using PLC, SCADA, HMI or DCS etc is called Automation.
Generally in which location ( JB or IO card or DCS) the
thermocouple compensation is done.Also where they measure
the atmosphere temp ( for compensation) in JB OR DCS panel?
How they compensating that atmosphere temp? is any circuit
for that ( like in rtd wheatstone bridge)?
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
know about me.but i request you please
help me these question are very usefull
for my feauture.plz sir

Please any one can explain how to calibrate transmitter
(smart) online with out remove from the container suppose
it is interface level or static pressure level measurement
we dont want to remove transmitter from the container mean
it is running plant please give me detail. thankx brothers
In closed loop control there are several “blocks” used to
show the interactions between the process and the control
system. These blocks are referred to as the “process” and
the “controller.” Describe the relationship between these
two blocks when creating a well tuned control loop.
