My project is to perform a simple clamping procedure using a pneumatic pressure regulator and air cylinder. I will be using a microcontroller (possibly Arduino Motor Shield) to control the pressure regulator, which takes a 0-10 V input. I wanted to be able to vary the voltage, though Arduino of course only relies on PWM.
I was thinking of buying the pressure regulator in the URL below (Part number 2859T3). I tried contacting the seller to see if the pressure regulator will work under PWM, but they were not sure. I'm not very experienced with pneumatic systems, so do you think it would be possible for the pressure regulator to register a PWM signal and output the desired pressure? If not, would I need to purchase some DAC device? If so, what would be appropriate?
