This is a good one. I am a materials engineer and I use thermocouples everyday to measure the furnace temp. Never knew how they functioned. TILL NOW! Thanks :)
This video really helped me a lot in understanding thermocouples. I was having difficulty understanding thermocouple in wikipedia. This video is really useful. Thanks and keep up the good work.
Amazing video! very enjoyable! Very useful information. if you are searching for Thermocouple manufacturing please visit our video ua-cam.com/video/yoVnLRLmK_k/v-deo.html
my physics professor had a nifty gizmo he showed in class, it used the same effect ; heating dissimilar metals to generate voltage. it was a copper bar wrapped around a 3/4" thick 2" diameter steel disk. both ends had large (1.5^2")plates, (didn't get a close view) but since the copper wrapped about 350 degrees around the steel disk, when he hit the plate with a torch, he produced an electromagnet that held up 8kg and i've been searching the web to find it. when it cooled the weights fell.
Muchas gracias Peter. Una excelente presentacion. Me gusto mucho el final y la medicion de temperatura en la carne. Muy sabrosa forma de terminar. Gracias.
Hey, maan! Nice video, nice channel! I'm a Control & Automation Engineering student from Brazil, and your channel is very usefull! Sorry 'bout the bad english!
When you boil water, you have to take into account the atmospheric pressure (determined by elevation). Water boils at 212F at 1 atmospheric pressure (1 atmosphere = 0.101325 MPa). So, at higher elevations the temp water boils will be several degrees lower. So if you want an accurate reference temp, you have to take that into account.
+John Smith true for water, but how often are you just measuring pure water temps in the real world? again, you're right but i don't think he had to spell that out here
this is really easy to understand because it has visual aid, straight forward and simple.. usually in a classroom, you only see letters and mathematical formula.. i think it lacks attraction..hence, students become bored and the understanding of the idea is lacking..or maybe they just care about exam and not practicality.. haha "better known as my basement" a good one..
Interesting but confusing, i assume since the reference has two different temperature he is reading the difference of the two 212 - 34= 178 = 4 millivolts. But i get that is a wire integrity test. Checking my type K table after i had guessed 178,, the table says 175.. Great video, i know understand how it all works. This must be how solar panels work.
Do you ever put joint compund or teflon tape on pilot light connection.I never seen a pilot light fitting ever having any dope or teflon.I just changed a gas valve and tried to use the gas pilot tube originally there and the there was a gas leak Are you supposed to put compund dope on a gas pilot light fitting?So then how do you fix the gas leak on the gas pilot tube fitting that goes into the valve. he new gv has its own fitting with like 3 or 4 extra threads do you force this on a pilot tube?
need help ... based on your voltage and mV values in type T tables it looks like you are getting close to 212 temperature difference, but I am confused ... if the ice water is 32 deg F then would the difference not be 212-32-180 deg f ... yielding closer to 3.459 mV?
More detail man. More detail! Chemistry, Zeeman effect and all. (Because now that I'm interested in thermocouples I gotta drag my ass to my bookshelves and look for my transducers book. And they said the Internet would be the end of books ;P) hehe
i thought the detail was ok, i had a lecture today on thermcouples (It was just an introduction, i'm a first year student) and it left me confused so i wanted to get some insight. one slight issue was the use of the term temperature gradient, i had to google what that meant.

What? Thanks for watching?!? Where the invitation to the barbecue? Kkkk, I am kidding; congratulations for your explanation.
So what is the main objective and hypothesis for this experiment anyone? coz I need it for my experimental investigation :) and also what are the list of materials? thanks! hope some of you reply.
I think on the hot side, some if the electrons gain enough energy to jump over to the other type of atom. Perhaps a nickel electron goes to the copper side. From there, it gets conducted to the cold thermocouple. The electron jumps from the copper to nickel. It loops back through the nickel wire back to its point of origin. As soon as the initial jump is done, an electric field exists in the entire wire loop and this guides the electron back to the point of origin. That's my guess.
ahh i see now thats why ma experiment is fail somehow i was trying to detect the voltage using multimeter set to 10v (minimum reading set) n nothing happening :| so dis makes sense the voltage was not enough to be detected by ma analog multimeter that had been set to 10v but even when i was set it to 500 or 0.5 dc mA the niddle isn't moving somehow :| both tried with only 1 junc n 2 different junc
Thermistor's resistance decreases with increase in temperature. So if I'm correct it can be used with ammeter and constant voltage. Not quite same as thermocouple though.
I like it well explain for vision impaired people i been scearching UA-cam for somebody to explain it what the micro volts and tempchture degree of boiling water was for a K thermocouple I own a talking Micronta 22-164 digital and a RadioShack 46-Range Digital Multimeter remenber this that vision impaired people has ears but no eyes now i need to find a K thermocouple data chart that my screen raeder JAWS can read simple or the formula to figger it out

love the ending, he even changed clothes :) Good to have some practical use :)
3.2 mV - looks like we're almost done here.

Good video. Very informitive. I never understood the concept before watching this you have a good method of teaching and communicating.
Thank You
Peter, My Instrumentation I class benefitted greatly from your demonstration as part of the presentation on Thermocouples. Well done!
Good video. It was well explained. Measuring the temp of the meat is a cool neat trick there at the end.
my physics professor had a nifty gizmo he showed in class, it used the same effect ; heating dissimilar metals to generate voltage. it was a copper bar wrapped around a 3/4" thick 2" diameter steel disk. both ends had large (1.5^2")plates, (didn't get a close view) but since the copper wrapped about 350 degrees around the steel disk, when he hit the plate with a torch, he produced an electromagnet that held up 8kg and i've been searching the web to find it. when it cooled the weights fell.

Thanks for producing this. Very cool application at the end of the clip!
Excellent and very useful tutorial. Thank you so much.

Thanks for your time and this great video. I appreciate you sharing your knowledge...
Thank you great Engineer,You are really helpful..
Keep moving in this-Good Luck
خیلی عالی توضیح دادین
very Good sir
Especial thanks for the Ice Bath and temperature gradient.
great tutorial! enjoyed how you used it to cook your steak to the right temperature. :P
very simple step by step, thank you.
Thank you so much for this video!

true for water, but how often are you just measuring pure water temps in the real world? again, you're right but i don't think he had to spell that out here
Yes, at 1 atm, water boils at 100 C. The mp is 0 C.

thanks for teaching us... can we generate 2 to 4 volts from temp not more than 60 degree's and if yes then which typ of thermocoulpe will be used ?
you make this stuff fun... keep it up
You Sir, are a legend.
this is good. I wish you made more videos
Thank u very much ,its a very useful video
Excellent video. Thanks
Cool vid thanks for that.
i have an idea on how to use it as a constant power source but i need your opinion on it if it might work?
Do you ever put joint compund or teflon tape on pilot light connection.I never seen a pilot light fitting ever having any dope or teflon.I just changed a gas valve and tried to use the gas pilot tube originally there and the there was a gas leak Are you supposed to put compund dope on a gas pilot light fitting?So then how do you fix the gas leak on the gas pilot tube fitting that goes into the valve. he new gv has its own fitting with like 3 or 4 extra threads do you force this on a pilot tube?
Why is the iced water being used in series to the heat source..?
Someone may explain me? Thanks
need help ... based on your voltage and mV values in type T tables it looks like you are getting close to 212 temperature difference, but I am confused ... if the ice water is 32 deg F then would the difference not be 212-32-180 deg f ... yielding closer to 3.459 mV?
Check the units you are using, is it in Fahrenheit?
this video was helpful thank u
Love it. how do you calculate the temperature from the voltage reading? How is the ref. junction (ice water) used as far as mathematics is concerned?
So well explained! Thank You!
thanks for the video.Are the two wires in the ice glass joined?
can u tell from where i will get the research paper regarding calibration of thermocouple
Great tutorial ! However, I was just wondering why did you use nickel and copper wires ? And can I use a substitute ? Thanks !
How temperature can be measured inside of combustion chamber of Gas Turbine Engines?
Very informative and entertaining!
How did you eliminate noise? Personally as soon as I turn the multimeter on, I get 0 to 2mv noise signal.
+cyrusIIIII
you change the range to as low as it goes, his was 0-300 mV. yours may not be be able to reach that though
Love the end test!!!
How do you know the temperature of a sample at some other reference junction with a table for the reference junction as 0C?
Great information
thanks alot
Can ligth a bulb? Or not
More detail man. More detail! Chemistry, Zeeman effect and all. (Because now that I'm interested in thermocouples I gotta drag my ass to my bookshelves and look for my transducers book. And they said the Internet would be the end of books ;P)
hehe
Thanks for sharing your knowledge
how dose the ice water work as a control, wouldent it act like a resistor being cold?
If so is the tempreture of the ice water the known vareable?
how can we use transistors instead of copper-steel wires...? thanks in advance..
i thought the detail was ok, i had a lecture today on thermcouples (It was just an introduction, i'm a first year student) and it left me confused so i wanted to get some insight. one slight issue was the use of the term temperature gradient, i had to google what that meant.
What?
Thanks for watching?!?
Where the invitation to the barbecue?
Kkkk, I am kidding; congratulations for your explanation.
Brilliant video! 5/5
So what is the main objective and hypothesis for this experiment anyone? coz I need it for my experimental investigation :) and also what are the list of materials? thanks! hope some of you reply.
Ya but how does this tie in to a flux capacitor?
great stuff
Thank you very much sir.
On an atomic level how is electomagnetic potential differrence created by creating more heat ?
I think on the hot side, some if the electrons gain enough energy to jump over to the other type of atom. Perhaps a nickel electron goes to the copper side. From there, it gets conducted to the cold thermocouple. The electron jumps from the copper to nickel. It loops back through the nickel wire back to its point of origin.
As soon as the initial jump is done, an electric field exists in the entire wire loop and this guides the electron back to the point of origin.
That's my guess.
thanks for the help!
This is just great! Now i ve a craving for meat. :P nice video btw...
Nice quality :)
Thanks
I can understand the working of Seebeck effect but i can't get enough idea of how heat energy is converted into electrical energy ?
3:12
If I understand your question the answer is:
It is in function of the grade of shake of molecules of materials.
GOD bless you.
thnx thnx thnx superb grt,,maavalous!!
yes, but I was wondering, I know that today it's in a pile drive format of ic chips. I thought it is called the pilfered effect.
Thank u...
ahh i see now
thats why ma experiment is fail somehow
i was trying to detect the voltage using multimeter set to 10v (minimum reading set) n nothing happening :|
so dis makes sense
the voltage was not enough to be detected by ma analog multimeter that had been set to 10v
but even when i was set it to 500 or 0.5 dc mA the niddle isn't moving somehow :|
both tried with only 1 junc n 2 different junc

Now what about thermisters? Are they the same as thermocouplers?
no thermistors are temperature depemdant resistors, whereas thermocouples are just thermometers using metal properties.
Thermistor's resistance decreases with increase in temperature. So if I'm correct it can be used with ammeter and constant voltage. Not quite same as thermocouple though.
nice one
Cool
man I screw up most of the time when I calibrate it using thermometer
I wish he was my prof
