hello i hope you are doing well
i have tocontroll a pneumatic cylinder using air compressor as energy source
i want to make a pgramme in order to make the actuator go in and out with a precision for the amplitude
i wish that you can help me how to do it with arduino or even if i have to use other tools
thanks
I'm not sure what you mean by "amplitude" in this case, but I'm guessing you want to be able to extend the cylinder varying amounts?
Pneumatic cylinders are difficult to control that way, due to the compressibility of the air. Is there any chance you could switch to hydraulic?
You might have a better chance of success with a hydraulic system that has a flow meter in it...
yet that whaat i wanted to say
fo examplei want that the cylinder extends with 3 mm in and same for out to get a mouvement up and down
for the hydraulic i didn t choose yet so it s possible
Another possibility is an electric linear actuator. That might be the best. Hydraulics can be very messy if you're not a good plumber. :-D
Depending on how much force and speed you need, something like these might be much easier to use and control with an Arduino.
i thought in the electric but i m not sure if its can make what i want as u said
i m working on fatigue testing machine so first the actuator must move so fast , and the electric actuator mosut stop to change the sens of motion that s not good for my project
and thanks so much for replying me
if u have other ideas or even if u want to know more information u r welcomed
