Should I use Analog or Digital input to read Vacuum pressure?

I am looking to order a Vacuum Pressure sensor, and I have the option of a few different types of output from it. There is a model with 0-10V analog output (Which I am sure will work), but there is also the option of a PNP Digital output. Is there a way to read the digital version?
The sensor I am looking at is from Festo, Documentation is here:
The reason that I like the idea of the digital output is that I may be able to read multiple sensors from one Neuron.....
Any input much appreciated!

A sensor with digital output will only give you information whether the pressure is below or above given threshold. You can connect it to digital input of UniPi. You have to decide whether this is sufficient for your project or not.
