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.
@SerpentM52
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.

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.
@5gallonsofwater495
Dang, I just realized that this is one application of Hooke's law. Where stress is proportional to strain or vice versa. Very cool.
@calebkern4116
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.

Good example to understand of Bourdon Tube.

Wow. More simple than I ever imagine.

i subscribed to this channel because of the video on pressure regulator. and then watched this one too. well done pal.
@roystiner3937
I'd like to request a video on Chillers as in for building utilities

You should do a Auto Shut Off Valve Next. Fun, and easy to do.
