A small important component for my "pick and place" machine #pcknplc is the pressure sensor, which can be used to detect whether a component has been successfully picked up or not.
Because if a component "clogs" the pick up tip, the pressure in the vacuum line between the pump and the tip drops noticeably. With the help of a suitable pressure sensor, it is therefore easy to determine whether a "pick" process was successful.
Since I was a bit overzealous when I bought a sensor that didn't fit when building my vacuum chamber (it could only measure a "positive" pressure) I ordered a few candidates to test this time. The sensor shown seems to fit nicely. Now all I have to do is print a suitable bracket and at the weekend I will finally start wiring the individual components. 🙃
