Transducers for Instrumentation

By Prof. Ankur Gupta | IIT Delhi

Learners enrolled: 558 | Exam registration: 3

ABOUT THE COURSE:

This course is designed with an aim to make students familier with the working principle of different types of sensors and transducers. The students will have an exposure to basic physics of the sensors and their importance in the real world applications. The students will also understand the structures of some of those sensors. The students will be provided an understanding on modern day sensors and technological advancements. The students will learn about generating the sensor data and conditioning it to make it suitable for electronics signal processing. The first objective of this course is to understand basic physics of transducers and their operating principles. The second objective of this course is to understand different types of transduction techniques for designing and developing sensors with the help of examples. The third objective is to interface the transducers with electronic microcontrollers for processing the signals.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.

The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).

Date and Time of Exams: April 27, 2025 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.

Registration url: Announcements will be made when the registration form is open for registrations.

The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.

Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.

Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

Please note that assignments encompass all types (including quizzes, programming tasks, and essay submissions) available in the specific week.

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Madras .It will be e-verifiable at nptel.ac.in/noc.
