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??
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!!!
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
I would like a video on pyrometers also. I work with thermocouples and RTD's everyday and being an electrician I understand them but I also work with pyrometers which I dont understand. I was pushed into a facilities eng. job at a ceramics company and find myself lacking in knowledge of extreme heat. They cook stuff at temps I didnt think possible like 3300C. Glad I was pushed. Never loved a job before this one.
Great video !! it really helps to know about the basics of temperature sensors. Could you give details about the advantages and disadvantages of each temperature sensor?
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!
@Engineercan i tell you what it is loke to have your ide. M noty stolen fkr fools like you to to know a little more about policies that you sighned up for but I didn't know that a person on. Here didn't without asking me
@@garrysekelli6776 According to the Google definition, "a device that converts variations in a physical quantity, such as pressure or brightness, into an electrical signal, or vice versa." Hence, why a better, animated explanation would be helpful.
Can you please have a video locating the balancing valves, differential pressure sensors, differential temperature probes and how sequencing of chillers and pumps are done. Basically the sequence of operation of the system with an illustration would be very helpful with all the parameters.
Great video! Quick question though, if RTDs are medium to high cost why would they be used on a thermocouple which is lower cost? Seems like you could just use the RTD and call it a day
@@abhinandanawasthi3814 you have to touch both the wire and the track to complete the circuit, just like the train. but that will also kill you so don't do it.
I love the channel. Best channel I have subscribed to. Thank you for starting this. I enjoyed this video in particular but you didn't talk about infrared sensors.
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.
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.
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
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
Suppose I want to measure the temperature of air in my compressed air system. Doesn’t need to be super accurate or have high resolution. I’d like to insert something into a copper tee fitting at various places and read the temperature. What would I use without breaking the bank? Thanks
Very good video 👍👍. But another important Temperature sensor used in large scale manufacturing plants is Gauges (Bimetallic strips connected to Pointers)which show accurate measurement without the need for any electrical input or measurement technique. Maybe you can cover a short video on those along with their applications on Thermostats
@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???
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.
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.
That's a good one. Where I work, controls basically use a lookup table and do a linearization between 2 temperature points. If you want to use a formula, you'll have to use the Steinhart-Hart formula
I have a problem I have tried to solve for years. Controlled from a computer, control at least 32 (off/on) switches, isolated, with a possibility of an acknowledge line back to the computer. What circuit will do it?
Top of my head I'd say use a raspberry pi to control an IC chip and piggy back more off that to give you 32 on/off points. Can then use relays off those to control larger circuits
Brother can you help me my chiller tube is leakage . now I got water inside the shell how can I remove that water from the shell . Can you explain to me in video .
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

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

I can't believe it can be this good
Awesome video,
Please make video on how train runs on electricity by only a single wire. How circuit completes by one wire only?
The track works as a ground.
@@LukeSumIpsePatremTe then why can't we feel shock on touching the tracks?
@@abhinandanawasthi3814 you have to touch both the wire and the track to complete the circuit, just like the train. but that will also kill you so don't do it.

It was very easy to understand 👍
Thanks
Thank you, Sneha
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

thank u so much for this great and useful video.
9:48 Only one data missing: "Speed". Which one of those is the first one to respond to temperature changes? Is it the high accuracy of the RTD ?
excellent explanation
Awesome video! I loved it
Thanks sir
Glad you enjoyed
I learned so much , thank you
so useful
What difference between temperature sensor and temperature transducer
Jove this channel but wish you could make it easier to understand
Good job
Perfect
What about temperature sensor that are based on infrared? How they know the IR light coning from something?
All thermal emission is infrared radiation. The IR thermometer literally reads the amount of infrared radiation that hits the detector.
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.

@@EngineeringMindset second this, fluid expansion temp switches too!
@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???
I think they're shorted using the voltmeter that gives us the voltage reading

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.
Is an RTD then technically also a PTC?
Well it has a positive temperature coefficient but it's not a thermistor because of the materials.
Why the neutral current is zero in Y configuration?
Sir pls would u make video about control valve and calibration and trouble shooting
Can you use ice water to calibrate an industrial thermistor and expect it to still be accurate when it warms up to around 30-40°C?
How long I can use T type thermocouple for regular measurement?
I agree, more accurate than mechanical thermometer which uses the materials expansion
Digital is the way forward
nice videos ! Coriolis mass flow meter coming soon ?
Which temperature sensor better performance one with temp higher than debye and one less than debye temperatur
Very useful thing are you doing and your explanation is superb.Thank you.
Electrons actually move randomly around the nucleus
Not in shells
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.
Super sir
Awesome 😎
please explain us varistor vs thermistor
I was right my logic won :)
Are NTC and PTC’s interchangeable?
If we pass current through wet wood, will it shock?
Thermocouples themselves are relatively inexpensive but the hardware needed to read them can often br a different story
Explanation to Temperature Sensors
what about infrared sensor or thermo imaging
Nice vdo.. thanks sir..
Thank you
Can anyone tell me how to determine the correct tip size for temperature sensor??
can you please make a video on 24 dc Governor control
make a video on linearizing a thermistor
