One thing i would do is derate the jack somewhat for example a 20 ton jack limit to the pressure equivalent to 12 tons.
Adding pressure gauge to floor jack.
Does anyone know how to do this if the jack does not have port for a guage.
Using the math discussed above we can calibrate the gage in tons adding marks on the face with a paint marker or other method.
Picked a 12 ton press off craigslist first thing i had to do was add a pressure gauge.
For instance with a 3000 psi gauge and a one inch area piston then it reads up to 1 5.
Lets me know just how much pressure i am putting on things in the press.
It really is a useful little tool.
The 20 ton heavy duty h frame shop press utilizes an air hydraulic power system that delivers up to 20 tons of pressing force.
Designed for fast easy installation hydraulic gauges are ideal for use in many applications specifically for high cycle and harsh environments force gauges measure external load supported by a.
The reason i want the guage is so that i can test the breaking strengths of various welds.
If you make the piston ten times bigger then the gauge reads in lbs times ten.
If you have another way of testing welds that is repeatable please let.
Use and ordinary pressure gauge calibrated in psi and fill the cell with oil.
First thing drain the fluid and tear it down.
Gauging hydraulic pressure from 0 to 50 000 psi.
Adding a pressure gauge to a hydraulic jack.
By tapping the casting you are adding stress risers to something that may not be well engineered in the first place knocked off and not analyzed or tested or operating on the outer window of safety factor already.
Having a gauge on this jack lets me know how much weight it is lifting or when in the press how much force it is apply.
Enerpac hydraulic gauges and accessories supply a visual reference for system pressure and force.
Idea copied off one of my pyro mentor s website.
Fyi it is a 35 tonne press with a hand operated jack.
I have wanted to do this for a while.
When components need to be removed or assembled this press delivers the controlled power to get the job done.
We may have to settle for a 10 000 psi gage realizing that the top 1 3 of the range is out of bounds for this jack.
Remember to calculate the size of your piston.
Adding a pressure gauge to a bottle jack.
If you make the area of the piston exactly one square inch then the gauge reads in pounds directly.
You could also use it to calculate the weight of something very large like lifting a house.
The author points out that a jack with a 1 1 8 inch ram will be within six pounds per thousand of having the pressure gauge read directly in weight this means the 3000 psi gauge shown in the project should not be coupled to anything beyond a 1 5 ton 3000 pound jack.
We need a pressure gage that reads something over 6 700 pounds.
