The Engineering Mindset Hi, i’m a fan of your videos, I’ve been watching them to get through school and they’ve really helped me understand things so thank u, but I was wondering whether u could do an explanation on the differences between conventional current and electron flow? Like are they the same thing cause like u said current is the flow of electrons in a circuit and and they flow from the negative terminal but conventional current flows from the positive terminal then soo??

Me too 😅😂

This is a great explanation. None of our engineers (including me) knew how the K-type thermocouples we use at work function. Now I know why I get such different readings when the thermocouple is hooked up to the wavelogger backward.

alot of his vids helps me with basics knowing and more advanced, working as an marine electrition, ive never studies cause i cant afford it, still live with my parents, but using your pdfs and vids to help myself understand what im working with and how it works, thank you🙌

THANK YOU so much! I am a mechanical engineer and still had not understood so well the differences and working principles of each sensor. . Your 10 min video was so much more efficient than the 6h throughout 2 weeks that my professors spent trying to explain the same topics to the class. . Even so most of us could not understand 100%, but now it is crystal clear

In hvac school online and they just say here read this after working 12 hours I was struggling at night trying to read like becoming cross-eyed and falling asleep. This video just condensed two weeks of reading into an interesting informative video thank you!!!

Just wanna say THANKS.

Great video we love temperature sensors, great timing. We use these sensors in our titanium oxidize, we just call it anodizing and in power coat baking oven set ups controlled temp and heated liquids required for best results and it is nice to learn more about them here. Thank you. Lance & Patrick.

OMG! This was super helpful, I had a superficial understanding but this helped me go a bit deeper so I now what I am seeing and reading. Thank you so much!

Really good explanation. Thanks!

I can't believe it can be this good

Hi Thank you for the video, great content. Is there a kind of thermal sensor just turning on or off following if we get below a temperature or above a temperature ? I struggle to find this kind of components. I dont want in my application what is the temperature between A and B. But just to know if the temperature is below A or above B. Thank you very much ! Ed

Hi! There is something i'm looking into right now that seems to be generally overlooked: When you have radiant heating sensors should be covered by a "black bulb". I cant find a good explainer video showing the difference between operating a radiant heating system with a regular temperature sensor and a black bulb sensor.

Super sir

Would it be possible for you to do a video on transducers ? You explain things much better than most engineers.

Hi sir. I am rather confused now. Is the thermocouple used with RTD in industry pratices?

Cold junction compensation is most likely handled by either an IC temperature sensor or a thermistor. RTDs are quite expensive for that

Explanation to Temperature Sensors

@1:57, ok the two different metals react differently to temperatures, but they are tied together, and thus shorted out....so how is there still a voltage difference???

@dioptre

3 жыл бұрын

I think they're shorted using the voltmeter that gives us the voltage reading

Hey, I did not understand the difference in working between the metal/conductor atoms and semi-conductor atoms. Why is one a PTC type and the other NTC type? Both ways of working are similar. Both must have increasing resistance to current flow.

@caffeinatedinsanity2324

2 жыл бұрын

I think it has to do with the materials used. I don't have any reference other than what I read on DigiKey, but I think NTCs use metal oxides while PTCs use, I think, ceramic stuff or polymer, can't remember. I'm not a chemist so I couldn't explain why this would affect its behavior

Can anyone tell me how to determine the correct tip size for temperature sensor??

Very useful thing are you doing and your explanation is superb.Thank you.

Thermocouples themselves are relatively inexpensive but the hardware needed to read them can often br a different story

Is an RTD then technically also a PTC?

You need to contact a specialist refrigerant recovery company in. The chiller will be contaminated with moisture and need to be treated, new oil and filter driers. The tubes tested and repaired, you might be able to plug the tubes if not many. Speak to the manufacturer

But how can the electrone moves to the cold place i mean why ,i want to know the force ,pllzzz tell mee pllzz i really want to know

It's a real pain when TCs fail too because they can fail in a way that is very subtle at first so anytime a negative temp trend occurs everyone wants to blame the TC first.
