Hello,
My goal is to measure the control signal used to control a proportional valve.I need to plot it into the same chart with pressure. (x=DC,y=bar).
We use 100Hz/12V PWM to control solenoidvalves.
Our x-y recorder can only deal with voltage.
How is this PWM-voltage conversion usually done? Filterig? What kind?
Digitally?
Commercial products?
(There are abrubt changes in the closed loop control signal)
Thank you for Your attention.
