I love this channel even though i'm not in the engeneering field

[@realpars]

Thanks a million! Great to hear that

[@SEALTRONICS]

You are the best, please keep on making new videos, instrumentation to the fullest, i like you guys too much, more lessons guys. Even 5 videos per week

[@realpars]

Thanks a lot, Amos! We appreciate your support

[@SEALTRONICS]

@@realpars I'm really inspired by you guys, , since i started watching your videos, I'm becoming the best Student for instrumentation Engineering, and i will be the best programmer soon

[@zainaabdin]

Something that I didn't know about....Very nice and excellent presentation

[@realpars]

Glad you liked it!

[@dhousermouthpiece]

Very informative video-thanks!

[@realpars]

Glad you enjoyed it!

[@divyan4271]

It was really nice explanation , could you pls share other instruments working process.

[@realpars]

Thanks for your comment and suggestion, Divya! Will happily pass it on to our course developers. Happy learning!

[@siva99444]

Thank you for this video. please put the video about Beckhoff plc.

[@realpars]

Thanks for your suggestion, Siva! I will happily pass this on to our course developers. Happy learning!

Tq sir and Tq for your reply about my message

[@africantales124]

Well explained.

[@realpars]

Thank you!

[@aminokamad1681]

speechless always awesome video 🔥🔥🔥

[@realpars]

Thank you so much!

[@balamurugan4993]

Team, kindly discuss about liner scale like potentiometric and magnetortive types

[@realpars]

Thanks for your topic suggestion, Bala! I will happily go ahead and pass this on to our course developers.

How amazing ❤❤

[@antonarasanastasopoulos3482]

I just learn all the sensors including lvdt in college...thats some nice videos ...next video will be strain gauge sensor right?😉😉hope you doing well mate thats a good work there... always better when you see those in action than a big pile of paper.nice one⚡⚡

Please make a video on MAGNETOSTRICTIV LINEAR TRANSDUCER.

[@realpars]

Hi Mukesh! Thanks for your message and your suggestion. I will pass this on to our course developers! Thanks for sharing and happy learning!

[@moaisl.3357]

Magnetorestriction is pretty robust and largely used in hydraulic applications, with high presision. I work with a combination of the 2. Lvdt in valve spool positionning (part on motion control system). While temposonic rods (magnetorestriction) is used for tool positionning.

[@realpars]

Thanks for adding that, Moaïs!

[@bitebonumbere1426]

Please RealPars how is the LVDT different from a potentiometer-type device? Nice video.

[@adisharr]

Look up how a POT works and then imagine the moving part of the transducer connected to the wiper of a POT.

[@bitebonumbere1426]

@@adisharr Many thanks.

[@realpars]

In a potentiometer, when the wiper moves, the resistance changes in the circuit. In an LVDT the voltage applied varies the magnetic field between the coils, thereby causing the push rod to extend or retract.

When you said “no passive device can produce energy”. The first component immediately popped into my mind was a thermal couple. Here you have a passive device as the ambient temperature increases it starts producing energy.

[@johnjones5354]

First, it's thermocouple, second, it produces an EMF proportional to the difference of temperature at the thermocouple junction and the reference junction.

[@coldfinger459sub0]

@@johnjones5354 = voltage = current = power

[@realpars]

A passive sensor is one that has no external power source. While it is true that a thermocouple produces a voltage between the measurement and reference junction, there is no current flow until you put the thermocouple into a measurement circuit. Even then, the current is very small. You can configure a set of thermocouples to produce significant current, but in that case, you have a thermopile, not a thermocouple.

[@realpars]

@@coldfinger459sub0 A car battery, not connected, has a voltage across the terminals with no current flow (no complete circuit). Your analogy is correct when a load is applied across the terminals.
