Re: Pressure Sensor

Let me see if I understand your question:

You want to limit the distance a pneumatic cylinder's piston will travel based on the pressure that is used to move it?

If that is indeed the intent, then I feel compelled to advise you that it is not a good idea. The piston's movement cannot be predicted that easily.

In general, a pneumatic cylinder's piston has two very well-defined positions: Fully retracted and fully extended. Those are the only two positions you can be sure about. Anything in-between cannot be assured easily, since the position of the piston will vary based upon the load on the piston.

In addition, you will need pneumatic solenoid valves that can provide an "all stop" position, where the air pressure on both sides of the piston are equal and unchanging. These are readily available, but are not supplied in the KoP.

My best advice is to find a different mechanism if you need anything other than full-extend or full-retract.

FYI: Bimba is the name of a company.
