A pressure gauge is a device that measures the pressure of a fluid in a system, the fluid can be a gas or a liquid. A Bourdon tube-type pressure gauge is a mechanical pressure-measuring instrument that operates without electricity. There are various types of pressure gauges that use different principles for sensing pressure. The C-shaped Bourdon tube type is the most common one.
In this 3D animation video, we will be looking at the key external components in order to understand how the mechanism inside the pressure gauge works.

Glycerine is not a "silicon oil".
Excellent, the sort of question that was rattling around in the back of my head without any real motivation to go a-looking for the answer.

Yes same, use them often but never looked at how they work.
Thank you, I now know how common pressure gauges work.
I always thought there was a spring loaded piston inside which the fluid pushes, not a tube that deforms. This is a really clever solution.
Watching this while my pressure gauge broke. I've seen it before but watching it again with the thing disassembled in my hands is something else.
I use a dry one for concrete testing and have to observe others use an oil filled one for post-tensioning. It's interesting to learn the reason for the oil and it makes a lot of sense in this context. With concrete testing (specifically when using the pressure method for testing air content), there's no change in pressure when the gauge is read. With post-tensioning, the guage is constantly changing and jumping around even with oil as the tendons are stressed. Without the oil, it might be nearly unreadable.
2:52 The spiral torsion spring aka hair spring doesn't help return the pointer. It's function is to remove the backlash of the sector and pinion gear by lightly applying torque resistance. This prevents the needle from being free to fluctuate under vibration.
Excellent work!
BRO keep it up, this channel is fantastic. Can't wait for more vids!!
Informative AND interesting!
Great explanation
Wow. More simple than I ever imagine.
Dang, I just realized that this is one application of Hooke's law. Where stress is proportional to strain or vice versa. Very cool.
excellent work 🤯🤯
Excellent video, congrats!
excellent and informative video!
Great video thank you
Glad to see you are getting sponsored!
Very informative video
Liquid vs dry filled. Vibration etc are important but also variance speeds, for example compression gauges are always dry as the sudden change in pressure could cause damage in a liquid filled guage. This is the most important aspect when choosing liquid or dry as the other points you make do have an impact on failure rate but will not be a consideration for general use.
This video deserves a lot more views.❤

I'll leave the gospel here: How do you get to hell? Very simple: claim that you're innocent. How do you get to heaven? Very simple: Admit that you're not Innocent, you're guilty and ask for mercy. How to know if you're guilty or not? Simply: Compare your life to the Ten Commandments God gave you in the Bible. Everyone agrees that if people followed the ten commandments there would be no need for governments or police. Do not lie. Do not steal. Do not commit adultery. Do not insult God by using his name as a cuss word. There are six more but let's just leave it at that. How many lies have you told in your life? Have you ever taken anything that didn't belong to you? Jesus said, if you look at a women lustfully you've already committed adultery in your heart with that woman. How many times a day do you do that? Do you use God's name as a cuss word? Would you do that with your own mother's name? If you answer these questions honestly you know that you're guilty. God can justly punish you and send you to hell. Ask him for mercy. His name is Jesus. It's as simple as this, The Ten Commandments are called the moral law. You and I broke God's laws. Jesus paid the fine. The fine is death. Ezekiel 18:20 - "The soul who sins shall die." That's why Jesus had to die on the cross for our sins. This is why God is able to give us Mercy. Option A. You die for your own sins. Option B. Ask for mercy and accept that Jesus died on the cross for you. ❤ **Honest questions are welcome.**
Wow well done video keep up good work
Thanks
I absolutely dig your content keep making more cuz I wanna watch like 5 hours of you scalping this stuff!
AAAA YES, NEED MORE VIDEOS LIKE DAT
Its very great❤
Can you do a speedometer, Love the channel!
I’m just waiting for someone to make a piston-controlled pressure gauge that uses platform gears to turn the knob. I feel like this method would actually be longer lasting.

A piston would suffer from static friction. The reading would tend to stick-slip rather than move smoothly.

Beautiful! Maybe look at a micrometer.
I need more…
Song is Ice and Fire for anyone wondering
would love to see an mechanical automatic transmission one day!
Nice video, excellent graphics, and clear explanations NICE JOB!! Not expected from a channel I'm not used to, but i think I'll be getting use to it by watching lots .ore
Thanks!

Why do you need a spiral spring to return the indicator, since the connection to the boudon is geared?
@patrickadair8503

Maybe to keep tension in the moving parts? Like when the tube is switching from straightening to bending back it keeps everything in the places it should be? Just an idea, id love to know too :)

@@patrickadair8503 maybe it reduces backlash.
recommended to me randomly after replacing three gauges todays.. thanks for listening google. Appreciate the video too
I always thought it was just a spring pushing against the liquid and a simple gear in the middle to transform linear to rotational motion. I guess the design in the video is more leak-proof
If you contionue this, I swear your channel will blow up. Only 4 videos and 56,5k subs and 1.3M views on the latest video sais it all.

We use Bender
so when the pressure goes up, the budon tube goes like the system reproduction of male human
I don't know what i thought was happening in there, but it wasn't that
Am I the only one who thought the pressure gauge was spinning to the right at the beginning and got mindfucked? No idea why my brain did that.
