Introduction to Sensors (Full Lecture)

- čas přidán 27. 07. 2017
- In this lesson we'll take a brief introductory look at sensors or transducers. We'll examine various methods of transduction for pressure, rotational speed, fluid velocity, flow rate, position (linear variable differential transformers (LVDT) and magnetorestrictive wave guides), level, vibration, and temperature. Additionally, we'll discuss transfer functions and the process of adjusting the zero and span of a particular sensor. Finally, we'll examine how sensors are employed in closed loop controllers and how closed loop controllers can automatically correct any errors and compensate for disturbances. (Full Lecture)

Thank you for this. I appreciate 🙏 the digital information. I will remember this for my work. Thanks!
thank you Jim at all your effort >>> you are the best lecturer
Thank you for the wonderful lecture.
Thank you very much for these videos, helped me a lot :)
thank for your instructive lecture
Many thanks Sir. help a lot
Very helpful
waiting for second part!!!!!!!!!!!!!!!!! aweosme u solved my problem with one sensor what i had problem to identivity
Nice job once again Jim. You even have referred to the correct acronym.
I'm assuming you're referring to the acronym LVDT? Which in your opinion is the correct T ... transformer or transducer? I have a tendency to use transformer (because that's what it is) but I've found a lot of technical literature saying "transducer". Either one is correct but just curious if you see the same thing I do on the street.
In order to satisfy your curiosity Jim, I do stand corrected if you were under the impression that I have seen the term "T" for "transducer"...
I do happen to recall the "T" in the acronym "LVDT", standing for "Transducer "" utilized on rare occasion, and I do believe it is indicated on the website " Acronym Attic" , but I now appreciate your clarification that "T" .actually stands for "Transformer" .
I'm always interested in the different terms employed by different industries. A farmer was telling me about a "bang-bang" valve once and it took me a minute to realize he was talking about a regular solenoid operated (non proportional) directional control valve. Makes sense ... bang its on.... bang its off.
@@bigbadtech In our plant, they are referred to as transducers in most of the technical literature.
These devices ARE transducers from my understanding of the term. (Converts one form of energy to another), but specifically they are transformers as indicated by primary/secondary winding's.
I think the first ones I came across were part of a powdered limestone weigh feeder in a coal fired power plant. The limestone would drop from above onto a plate which twisted a shaft and deflected the LVDT. I was impressed. It was 1994.
safi sana
Deep very deep
At 27:11 there's a magnetostrictive sensor, not a magnetorestrictive. Thank you for your job, Jim!
Good catch! I had a student a couple years ago that was a former English grad and she came into my office one day and said "You know it's "respectively" not "respectfully" when you're pointing something out." I came to the dramatic realization that I'd been using the term incorrectly my entire life! She also took it upon herself to point out that I never combed my hair.
Wow, she's a brave student) I wouldn't dare to point out on my teacher's haircut.)
It was one day, when i saw chinese magnetostrictive level sensors with 4-20 ma transmitters in my factory. i was amazed and didn't realize how it worked, until i read one american article in the internet. I couldn't find russian article at first. So i wanna say again - "Thank you USA!"
I'm from Russia and have difficulties to understand English, especially some slang expressions. But i keep trying. I'm looking forward to your new lessons. Thank you.
Introduction to Sensors
small typing mistake in 11.51sec,in your min 50 psi pressure and max 500 psi example divider of 0-5v is 0-500 psi. how it happen ?
Good catch! Yes it should be 5/500-50=5V/450psi for the 11.1mV/psi transfer function.
Sir when you teach us servo motor drives and encoder concepts.....we are eagerly waiting....
Stay in touch because once I finish up the basic electronics series I'd like to cover more advanced concepts.
Sure sir....no doubt...
your classes changes my career and increase my value as a engineer....
Thanks once again.....
My problem is that I always remain in a deactivated state.
