The FX12-AIR is pressure sensor that can convert 0-1000mm of water in to .2 to
10V voltage output. It could also be used as a blow test detector or really measure the
pressure of anything (in theory as a scale as well). There is a version
that has a solid state relay output to trigger at a set point.
If
you use the analog output version, it can be run to a FX350 or other FX controller and drive all
the logic you’d need. The SSR (solid state relay) version could open a
maglock when a certain pressure is reached, but no further logic, latching,
etc.
