Case Study (9 Hours) Examples chosen from local industrial situations with particular attention paid to the basic measurement requirements, accuracy, and specific hardware employed environmental conditions under which the instruments must operate, signal processing and transmission, output devices:

a)Instrumentation for a power station including all electrical andnon-electrical parameters.

b)Instrumentation for a wire and cable manufacturing and bottling plant

c)Instrumentation for a beverage manufacturing and bottling plant

d)Instrumentation for a complete textile plant; for example, a cotton foil from raw cotton through to finished dyed fabric.

e)Instrumentation for a process; for example, an oil seed processing plant from raw seeds through to packaged edible oil product.

f)Instruments required for a biomedical application such as a medical clinic or hospital.

g)Other industries can be selected with the consent of the subject teacher.

Practical:

The laboratory exercises deal interfacing techniques using microprocessors, microcontrollers. There will be about six lab sessions which should cover at following:

1.Simple and Handshake data transfer using PPI

2.Basic I/O device interfacing like keyboard, seven segments, motors etc.

3.Analog to Digital interfacing

4.Digital to Analog interfacing

5.Design exercise (small group project)
