1. Question paper will consist of total 7 questions, of 20 marks each.
2. Only 5 questions need to be attempted.
3. Q.1 will be compulsory covering entire syllabus.
4. Remaining questions will be of mixed nature.
5. In question paper weightage of each module will be proportional to the number of respective lecture hours as mentioned in the syllabus.
Practical examination will be based on one experiment performed from the list of
experiments given in the syllabus and the oral will be based on entire subject.
Term work consists of minimum eight experiments, industrial visit report and a written
test. The distribution of the term work shall be as follows,
Laboratory work (Experiments and Journal) :10 marks Test (at least one) :10 marks Attendance (Practical and Theory) :05 marks
The final certification and acceptance of term-work ensures the satisfactory performance of laboratory work and minimum passing in the term-work.
Oral Examination Based on object–oriented Industrial Visit
Visit to a process industry & calibration institute to study transducer specification &
calibration procedures. The student should submit the detailed report containing the list of seen transducers with their specifications & calibration procedures.
The transducer specification should be studied with respect to following points i) Interpreting manufacturer specification sheets.
ii) Transducer type
iii) Operating principle iv) Accuracy
v) Linearity vi) Hysteresis
vii) Environmental operating limits
The student should submit the detailed report depending on the observations made. The concerned teachers of subject Transducer-II will co-ordinate the visit. Oral examination will be based on the visit report.
