FREE Online Lectures on Industrial Instrumentation

A 40 Hour Video Lecture Series

by: Prof. Alok Barua
Department of Electrical Engineering
IIT Kharagpur, India

We have featured several educational video lectures on Temperature Sensors in Prof. Barua’s online course, (Numbers 8, 9 and 7 on Thermocouples, RTDs and Thermistors, respectively) but realize the depth and extent of just this one component of the NPTEL Courses available online for free is something special!

Below is a list of the courses available via YouTube and The NPTEL Website in this the Electrical Engineering :: Industrial Instrumentation Series along with his first video lecture in the Series.

Forty Lectures online,  just in this series and more than 4,000 available at no cost except your time and willingness to learn! Incredible!

Here’s the list of the 40, approximately one hour, lectures in this course. Note several others, such as “Signal Conditioning” and “Problems on Temperature Sensors” have a bearing on the use of temperature sensors. The number in brackets represent the lecture time as [hh:mm:ss]

As Found Calibration Data

This free, online technical paper from Burns Engineering discusses why the resistance at the triple point of water (RTPW) is considered the most important piece of information obtained during calibration of a Secondary Standard Platinum Resistance Thermometers (SSPRT).

It goes further, telling how the change in the RTPW can be used to estimate changes at other temperatures.

They also have a second related paper on their website, entitled Using an Ice Bath to Approximate the Triple Point of Water. This paper describes two methods for approximating the TPW resistance measurement of a SSPRT using an ice bath and provides a detailed uncertainty analysis to show what level of uncertainty can be achieved.

Both papers may be freely downloaded using the links above or by visiting the “Technical Papers” webpage on the Burns Engineering website.

Both papers and many of the others listed are in PDF File format. They may be read using the free Adobe Acrobat Reader, downloadable by clicking here: (Adobe Acrobat Reader).

Error Sources That Effect PRT Accuracy

Platinum Resistance Thermometers (PRTs), a subgroup of Resistance Temperature Detectors (RTDs), are are far more precise than thermocouples and more nearly measure at a point, rather than along their length. They, however, have limitations and there are specific error sources to be considered in specifying and engineering an installation of one or more devices.

Burns Engineering has published a series of free, downloadable technical papers that detail these factors. They are online and their descriptions and links to them are in the table below:

Error Sources That Effect PRT Accuracy Presentation for Midwest Chapter of NCSLI. An PowerPoint Presentation that can also be opened in the free Open Office program Spreadsheet or in Microsoft’s free PowerPoint Viewer program.
Part 1, Interchangeability

NOTE: In PDF Format.Can be read using the free Adobe Acrobat Reader.

This is the first paper in a series on error sources that affect the accuracy of industrial PRTs. This paper covers the topic of interchangeability, defines what it means, and gives information on the magnitude of the error and some ways to reduce the error from this source.
Part 2, Insulation Resistance

NOTE: In PDF Format.Can be read using the free Adobe Acrobat Reader.

This paper discusses how insulation resistance (IR) affects the accuracy of PRTs. Information is provided on acceptable levels for IR as well as estimating the magnitude of the error due to low IR. Some suggestions are given on how to reduce the likelihood of encountering IR problems.
Part 3, Stability

NOTE: In PDF Format.Can be read using the free Adobe Acrobat Reader.

This paper discusses PRT stability, it defines what it means, gives examples of the magnitude of this error and what can be done to reduce the error from this source.
Part 4, Repeatability

NOTE: In PDF Format.Can be read using the free Adobe Acrobat Reader.

This is the fourth installment in a series on error sources that affect the accuracy of industrial PRTs. This paper covers the topic of repeatability, defines what it means, and gives information on the magnitude of the error and some ways to reduce the error from this source.
Part 5, Hysteresis

NOTE: In PDF Format.Can be read using the free Adobe Acrobat Reader.

This is the fifth installment in a series on error sources that affect the accuracy of industrial PRTs. This paper covers the topic of hysteresis, defines what it means, and gives information on the magnitude of the error and some ways to reduce the error from this source.
