Pressure-ok sensor?

Pressure-ok sensor? was created by JetForMe
In my CNC router table build, I'd like to include a pressure-ok sensor, so it doesn't try to operate the ATC unless there's good air pressure. I'm looking for a 24-V sensor that has a 24 V output, and something like a 1/4" NPT female port, available in different threshold pressures, like 120 psi. I've done some googling but haven't had much success finding anything.
Anyone have any recommendations?
Thanks.

Something like this should work:

Beware compressor control switches as they will have very high hysteresis

Correct. I think the 12 volt one in my 4WD is like 100 psi on and 150 psi off which is ideal when you want an air tank with > 90 psi in it and enough air to reseat a tubeless tire on a rim.

Hmm. Anything from a reputable vendor? I'm willing to pay for quality. What I wanted to avoid was building an interface circuit for it to my 24 V Mesa digital I/O.

A pressure switch doesn't need any interface
I would chose a NO switch
Here is a switch from a more reputable supplier:

What pressure ?
For 2.5 to 3 bar, use car manifold pressure sensor at 10 to 20 euro new, very reliable and measure from -3 to 3 bar, depending on the model. Analogue output from 0.2 to 4.8V.
For 5 to 5.5 bar, use a plasma air pressure sensor, no price info, they are used in all smallish plasma cutters, 7 bar on big ones. Digital output, NO or NC pins.
If space is no issue, use a compressor pressure switch used on all compressors to turn the motor on or off, they are all adjustable for low and high limit usually up to 11 bar. Here 17 euro a piece.

the Festo ones work like a Induktiv limit switch
Festo 527467 Drucksensor SDE5-D10-O-Q6E-P-M8
25Euros
its 0-30V
and 0-10bar
you can edit the point of trigger

No it is 15 to 30V
