I have a project that I've been working on for awhile and I've recently decided to try and upgrade parts of it. However, my knowledge on the subject is pretty sparse. What I want to do is have a vacuum pump which will shut off when my chamber reaches a certain level of vacuum. If anyone could point me in the direction of literature and or parts I will need I would really appreciate it.

Google vacuum pressure switch.

But do you really want to switch the pump off? Won't that release the vacuum? How much vacuum is it?

I dont have the exact vacuum i need on hand but it's not much, ive been using a sort of hand pump piston i made until now. Will it? I had assumed that the pumping chamber would be air tight and serve to hold the vacuum until i could seal the valve to the vacuum chamber.

Also would i be able to use a cpld circuit with that?

Air-tight checkvalve in the vacuum line would do it.
