I never seen the inside of a pressure gauge before and always wondered how it works. I am a mature student maintenance apprentice based in the UK and this has helped so much. Thank you Mr Pete!
I've made the decision to watch one of your videos every day until I've seen all of them. They really are both entertaining and informative and we thank you for making them.
Hi Mr. Tubelcain, I've known for many years how these things work, but have never seen a demonstration like this. I hope that a lot of young dogs will be viewing this! Thanx!
Awesome Mr. Pete. I usually am the guy wondering how things work, taking things apart, etc, but it never occurred to me to consider a pressure gauge for some reason. I use them all the time, but had no idea how they worked.
you are the excellent teacher, the explanations and the reasons are head on. i am mechanical engineering student and your channel is the best one to get the practical knowledge. thanks a lot.
Mr. Pete!! Thank you so much for this video. My gauge in my air tank will not zero out. Now I know how I can calibrate it. You’re right, never before seen on RUclips! Take care, Sir!
Pete thank you so much. I’m making a miniature one for a steam engine and was having trouble understanding the bourdon tube. Now I do. And of course I was delighted to see it was Tubalcain when I found it.
Thank you Sir....Well Done ... Again thanks for showing the inner workings of bourdon tube ... very much appreciated. You are an excellent teacher and all of your teaching videos are going to live ever...
What a wonderful legacy you are leaving for future generations. Highest regards to you for sharing your time, knowledge and skills with the whole world!
Thanks for a great instructional video! I have a bicycle floor pump, with a similar gauge, that I guess I must have dropped a few years ago. Since then, it has read about 15psi at no pressure. I have always just added 15 to the reading. After watching your video, I opened it up and was able to squeeze the curved "loop linkage" with a small pair of needle-nosed pliers to re-calibrate it to read zero at zero pressure. I then checked it on a tire pumped to 50psi against a new pump and it was bang on! Thanks to you, I feel like I have learnt and accomplished something today!
Again your rears of knowledge helped me solve a problem,milton compression tester would not zero.by bending the brass loop,fixed the gauge,and tested accurate Mr Pete you are the best preciate ya
I’d never explored the inner workings of a pressure gauge until just now. I am north of (60) years old and taking Operations and Instrumentation courses at TSTC in Marshall, Texas. Again, I’ve used air-pressure gauges in all kinds of work oblivious to their mechanics ... until today ☀️ A note of thanks for your guided tour. How It Works - Bourdon Tube. I took detailed notes that I might describe it’s working as well. JA Frazier, Marshall, Texas
Great analogy with the party favor, Mr. Pete. Pretty interesting engineering when you think of it. The radial travel of a specific type of formed copper tube expanding/contracting in some preconceived pattern, translated by gear ratios, and the linear linkage/ adjustments to a rotating shaft, needle and linear scale...impressive. Eddie currents are another favorite. Thanks!
Thank you so much for this in-depth informative explanation. I hope all your videos are like this as I’ve just subscribed. You explain things to us like my father used to, the do’s don’ts why’s and why not’s and all the outcomes. Please stay well and keep educating us with your videos. I’m 60 now and still learning, What a wonderful world. Kindest regards Ash from Scotland 🏴
That's really awesome! Never before have I seen how these work. I can't wait to see your other videos as well. Thank you for creating these very educating videos.
Very nice demonstration and explanation! Have never pulled one apart to see how it worked! I grew up in Amboy, IL on my parents farm. (just north of you on route 52) my high school shop/welding/carpentry teacher was just like you. Very talented at explaining and teaching young minds. Mark Streit was his name. Keep up the vids. I live in Indianapolis,In now. I always pass by your town on our way to my parents and say " theirs mr Petes place!" 👍🏻
Again a very interesting video.The picture quality and camera work are excellent. The gauge looked very good quality to say it was cheap, not like fancy looking plastic crap we are forced to buy nowadays. Thanks for sharing.
of all the things I took apart as a kid, one of these gauges was never at my disposal to look into.....I always figured it was some sort of spring loaded plunger, but this seems like a far more durable, and ingeniously elegant method.....thanks!
Marvelous as always. I expect that the ever so slightly greater surface area in the outside radius of the tube is causing the tube to try to straighten out. Like the Chinese windless. The differences doesn't need to be much. Thanks again.
It's quiet awesome, as i wondered how did such tings work since longtime now, and now i remember that i've already seen such mechanism pictures but forgot them. Very inspiring, it gimmes some ideas now about making some, calibrate them approximately following another one as a reference pressure gauge, and digitize the apparatus with some potentiometer, to plug that on a microcontroler for cheap. Thanks !
Hi LyleYes excellent once again. I deal with pressure gauges every day at work. mainly cheap ones. working from 0-15WC which is about 1/2 PSI to 10,000PSI. I design pressure washers. The low pressure ones are for gas pressure and the high pressure ones are for the water. Huge range and everything in between. The zero is normally done with the needle it is on a taper on the spindle and that little loop is to adjust the linearity. i.e. 0 is obviously 0 but 100psi might be 95psi and it changes the distance of the link radius. thereby changing the leverage and hence the linearity. Simple but effective. Never had to adjust one so far. You have to be careful with the LP ones, a colleague blew in one once and I shouted but to late it was wrecked. Allister
i converted one to become a DTI using the mechanism as the means to turn the needle disregarding the boron tube. a curved shaft to enable them. indicator pin to deflect the required indicator. yes, interesting worked a treat, to centra job remember were needs must the devil drives the way.

Fantastic. "Never before seen on youtube." I love that line. Great post!
+mycompasstv Thanks
I just wanna know from where the pressure is entering and forcing the that copper coil to move !
The air enters through a manifold and actually travels into the bourdon tube.
Great explanation, but that line really took it to another level 😂
As a lecturer in engineering. This has really helped me explain this. You are brilliant.Thank you.
👍👍👍
Mr. Pete. I would have loved to have had you as a teacher. Oh, my mistake, I have you as a teacher now. Thank you.
+Roy Lucas Thanks
I never seen the inside of a pressure gauge before and always wondered how it works. I am a mature student maintenance apprentice based in the UK and this has helped so much. Thank you Mr Pete!
Never before experience. This is the TRUE way of teaching the mechanism
I've made the decision to watch one of your videos every day until I've seen all of them. They really are both entertaining and informative and we thank you for making them.
I learn something new every day. At 62 years of age, I look forward to your shop class on RUclips.
+Monte Provolt Thanks
Hi Mr. Tubelcain,
I've known for many years how these things work, but have never seen a demonstration like this. I hope that a lot of young dogs will be viewing this!
Thanx!
Very interesting Mr. Pete! Your manner of teaching makes it very entertaining for us 45 year olds!!!
As always, clear and simple. Many thanks for another superb video Mr Pete.
Awesome Mr. Pete. I usually am the guy wondering how things work, taking things apart, etc, but it never occurred to me to consider a pressure gauge for some reason. I use them all the time, but had no idea how they worked.
Good video Mr. Pete. I think that's the only thing I never tore apart to see how it works. Thanks for doing the honors.
you are the excellent teacher, the explanations and the reasons are head on. i am mechanical engineering student and your channel is the best one to get the practical knowledge. thanks a lot.
Tha ks so much, I was trying to understand this while reading a textbook on the subject and I'm really a visual learner so I appreciate your efforts
👍👍

Never thought how pressure gauges actually measure pressure. Thank you for the great explanation and demonstration!!
OMG Tubalcain! Work and learning throughout my life always brings me back here!
👍👍👍

thank you so much for making this video, sir. i have an essay on how the guage work and i've never touched one before so i had to seek youtube's help.
Once a teacher always a teacher. Fantastic job. Thank you.
+Terry LaRotonda Thank you very much
This video is amazing! I use it all the time to explain how pressure transmitters on aircraft work! We love THE BOURDON TUBE!
Thanks
I have learned a lot by watching this series. Keep it up.
Great MrPete, Many thanks from a mechanical engineering student.

Thank you, it's a very helpful demo for my class.
Much vivider than 2D images on the textbook.
Thanks, I'm glad I clarified it for you
This helps me with my science exam! Thanks for making this video! :)
Man I wish there were still shop classes and teachers like this. Adding this to my homeschooling playlist.
👍👍
Loved it, thanks... helps me understand some of the theory concepts for my forthcoming IE exam

Thanks for sharing.
+Nodrog Awson Thanks
Another top-notch presentation ... Clearly, you were, and still are, a superb teacher.
+carver3419 Thanks
Thank youu!! Very informative and just explained simple but thorough. This is going to help me with my test I'm about to take for BioManufacturing
I knew how they work...But now I know how they are calibrated Thanks for the Very detailed video !!!

This is great. I've never taken one of these apart. Now I know how to make an adjustible pressure switch.
Excellent clear demonstration.
Excellent tutorial as usual mrpete. regards from the UK
+Gary C Thanks
About to start a job in a calibration lab. Thanks for this video
Exactly what I was looking for; seeing a bourdon tube in action!
You did an exceptional explanation 🎉
This was very helpful! Something my aviation school failed to elaborate on....Thanks!
Thanks
Fascinating. What an elegant piece of mechanical technology.
+MrSpinteractive Thanks
Thanks! I love the old, ornate, fancy pressure gauges. I have a 6" Ashcroft air gauge that is probably 50 or more years old.
+davida1hiwaaynet Thanks
Very useful and informative video, thank you for your time and endeavour.
Amazing! I'm currently studying Chemical Engineering and this is really helpful for me. Thanks!
Thanks
What a great subject. They just get better.
Thanks for your time.
+Lee Waterman Thanks
Very detailed explanation, beautifully captured to video. Thanks
Thanks
Thanks for this practical presentation. I want to observe how you are applying pressure to the pressure gauge.
Excellent presentation! Thank you!
Marvelous as always. I expect that the ever so slightly greater surface area in the outside radius of the tube is causing the tube to try to straighten out. Like the Chinese windless. The differences doesn't need to be much. Thanks again.
Very good explanation 👍 very helpful, thanks
You're the best at explaination.
Thanks
Excellent presentation.
Very educational and very good quality.
Quality video. Happy valentines day!
+Ron Icard Thanks
Great informative and entertaining video!
Very interesting, I did not know that. Thanks as always Mr. Pete!
+ShysterLawyer Thanks
Thanks for sharing , I had no Idea of how they worked.
Excellent presentation, thank you, sir.
Thank you for explaining that. Very easy to understand now.
Thanks for posting this video! very useful! Exellent explanations and views!
Thanks, Peter, very helpful video!!!
Glad it was helpful!
thanks so much for this video. useful and informative. and yes, never seen one like it in you tube

Moholo 88 Thanks :) (but i just found that fun as a project)
+Okto Putsch Thanks
Very interesting. Our friend AvE tested failure point on one of these and it went many many times past its range before the tube bursted.
+phooesnax Cody'sLab opens one up and discusses its workings in his video "Oversized Pressure Gauge"
+Neds Head I'll check it out
Another great video. Thanks for posting.
Excellent! Thank you for sharing.
wow it was awesome. it cleared my doubt of bourdan tube. and how it works.
Good job man seeing this for the first time
👍👍
I like this pretty well. shows detail to students.
Great video and wonderful explanation, thank you very much from Great Britain
Thanks
Thanks Sir for learning how the pressure gauge work, I understood that, If over pressure come. The pressure bar will broken...
Very fascinating device!
Fantastic video, very informative.
EXCELLENT PRESENTATION AND VERY PRACTICAL
Thanks
