6. Why to Study Instrumentation &
Measurements Course
❖Instrumentation is all about measurement and control.
❖Being an electrical engineering, core objective is to design, operate and maintain machines.
❖While dealing with real world measurements are the core area of interests.
❖Engineering as a profession is strictly associated with the Measurements and Instruments.
❖Industry 4.0, The Information Age, Rise of Artificial Intelligence, and Global Trends are the true
motivation.

7. 1-Introduction to Measurements
❖Measurement techniques have been of immense importance ever since the start of human
civilization.
❖To regulate the transfer of goods in barter trade to ensure that exchanges were fair.
❖19th Century began industrial Revolution, causing rapid development of instrument.
❖In late 20th century, an exponential growth in the developments of instruments has been
observed.
❖Specially, after emergence of digital technologies, fast processing and artificial intelligence.

13. 1.3-Elements of a measurement
system
❖Measuring instrument is basically a measuring system based on:
1. Primary Sensors: Liquid-in-glass thermometer
2. Transducers: Where the output variable of a primary transducer is in an inconvenient
form and has to be converted to a more convenient form.
3. Transmitters: Electronic amplifier
4. Recording Point
5. Display

14. 1.4-Choosing appropriate measuring
instruments
❖Choosing the right measuring instrument is the most important phase.
❖ Accuracy, resolution, sensitivity and dynamic performance are the key parameters in this
process.
❖Measurement systems and instruments should be chosen that are as insensitive as possible to
the operating environment.
❖Instrument choice is a compromise between performance characteristics, ruggedness and
durability, maintenance requirements and purchase cost.
