2. What is instrumentation system
• The term “system” refers to a set of components that
are connected to form and act as an entire unit.
An instrumentation system is collection of
instruments used to measure, monitor, and control a
process.

3. Why instrumentation is required
• some devices are used for measuring the physical
quantities such as temperature, pressure and so on ,
which are called as instruments.
• industrial instrumentation are required to control
various operations in industries

4. What is use of instrumentation
• Instrumentation
It is collective term for measuring instruments that
are used for indicating, measuring and recording
physical quantities such as flow, temperature, level,
distance, angle, or pressure.

5. What is instrumentation process
• It is the variety of measuring instruments to monitor
and control a process.
• It is the art and science of measurement and control
of process variables within a production, laboratory,
or manufacturing area Measurement parameters such
as Pressure, Flow, Temperature.

6. What is the role of instrumentation
in an industrial process
• Process Instrumentation in Oil and Gas. Process
instrumentation is an integral part of any process
industry because it allows real time measurement and
control of process variables such as levels, flow,
pressure, temperature, pH and humidity.

8. Functions of each block
Primary sensing element:
This first receives energy from the measured medium
and produces an output depending on measured
quantity.
Variable conversion element:
Converts the output signal of the primary sensing
element into a more suitable variable or condition
useful to the function of the instrument.

9. Continue
Variable manipulation element:
Manipulates the signal represented by some physical
variable, to perform the intended task of an
instrument. In the manipulation process, the physical
nature of the variable is preserved.
Data transmission unit:
Transmits the data from one element to the other.

10. Continue
Data presentation element:
Performs the translation function, such as the simple
indication of a pointer moving a scale or the
recording of a pen moving over chart.
