For all other instrumentation 4th sem syllabus for diploma m scheme tndte you can visit Instrumentation 4th Sem Syllabus for Diploma M Scheme TNDTE Subjects. The detail syllabus for measurement of process variables is as follows.
Rationale:
Instrumentation engineers must be conversant with the details of measurement of process variables in industries. In any process industries, the major process variables involved are temperature, pressure, flow and level. This subject covers the detailed study of principle, construction, operation, advantages, limitations and applications of the various transducers used in process industries. It also helps the students to understand about the availability of various transducers by different principles to measure the same process variable. This subject gives an idea about the selection of transducers for a given process variable by analyzing the advantages and limitations of each transducer.
