Thank you :) I want to understand the charging and charge measuring process better. A year ago I tried to just put the piezo nozzle, charge electrode and charge sensor together and tried to measure the charge, but it did not work very well and when I broke one amplifier I also saw that the result was not repeatable with other amplifiers. Now I want to try it step by step, starting with large drops at low frequency and a simple setup. My plan is to build my own amplifier next for measuring these drops and if everything works well I want to increase the drop frequency and reduce the drop diameter until ultimately ending up at 0.1mm drops at 40000 to 60000 drops per second for the CIJ printer. What I learned so far is that shielding seems to be very important to not pick up noise like the mains frequency with your charge sensor on the way to the amplifier.
Looks like you're making good progress! What's the end goal here?
Thank you :)
