overloading guages

Can you break a guage by putting more pressure in it than it reads?

You can tell how awesome a cannon is by the pressure used.

You can break anything if you put enough pressure in it :wink:

Yes.


If you overpressurise it it might give very wrong readings for ever. Like not being at zero unpressurized. It might also start leaking.

Yes. Don't you just love it when the answer is simple? :)

The damage will vary with the amount of overpressure.(NO,... REALLY?)

From least noticeable to most;

Loss of accuracy (gauge error increases but gage still comes to zero)

Gage does not zero anymore, accuracy is a thing of the past.

Ran the sector off of the pinion gear and gage is "stuck", oops!

Bourdon tube ruptures,...Ka-Freaking-Boom. Enough said.

Should I ask "Why do you want to know?" :wink:


Edit: Must learn to type faster. :D

Anyone knows how much a gauge can be overpressurized before damage occurs? Bringing a gauge up to 105 or 110% of its intended pressure isnt really something to worry about, but what is the limit?

Ofcourse different brands and different gauges will give different results...

Darn! I hoped for an answer like: "Most gauges tend to get damaged after exactly one round, thus being on 0 again." or "Some gauges get damaged after 105% and some others after 115%"
Wich would allow me to know how close to the 35 bar I could push my 25 bar gauge without having to remove it....
