FREE 46 Hour HVAC Video Course

A FREE Online Course from NPTEL:  Lectures by Prof.M.Ramgopal,  Department of Mechanical Engineering, IIT Kharagpur, India

Note: The links at NPTEL have changed as have those at YouTube for this and many other courses. They are all apparently still available on YouTube. So, the YouTube links have been added where possible.

If you need to find the links, use the YouTube search engine to put in the course title or lecturer. (It’s a pretty painless way to go since Google owns YouTube)

Temperature Measurement – Lecture 9

“The Science & Art of Temperature Measurement”

The first Lecture in Module 2, on the first topic of the Mechanical Measurements and Metrology, a part of the course from the Indian Institute of Technology Madras, India – online at youtu.be/GNOI_7ftbQ0.

It assumes an educational level of at least first year college engineering or higher, Some of the topics in this series of lectures also assume some knowledge of prior lectures in the Series (see below).

This is but one of the 50 videos in this course. A full list of the course contents is below.

The courses related to temperature measurement in this series are Numbers 9 through 19, inclusive, titles illustrated in red below. Additional lectures in this course detail related topics in measurement errors, and measurements of thermophysical properties of matter, subects that any serious student of temperature measurement should know well, indeed. The tiles of the latter lecture topics are shown as green in the list.

All of these lectures may be seen here or on YouTube.com, or on the NPTEL website at http://nptel.iitm.ac.in/video.php?subjectId=112106138, where flowplayer is used to display the lectures. Read more Temperature Measurement – Lecture 9
