So my current project needs to have a PWM controller to adjust the speed of some peristaltic dosing pumps. Its important that the controller doesn't get bumped by accident. So I was wondering if there is such a thing as a locking potentiometer?
So I was thinking of buying something like this to controll the speed.
And then replacing the potentiometer with something like this. I'm not sure if that would work, this is more of an example of what else I'm thinking if there isn't such a thing as a locking potentiometer.
If you have any other ideas please let me know. The motors that run these pumps are 12v and draw about 200mA at full speed. Not sure if that changes once they start drawing liquid or not though.
Just looking at pictures, I've attached a few things that might work physically, but not necessarily correct for a replacement potentiometer. That's why I'm here, asking for a correct option.
