Hello,

I've got a question about a honeywell absolute pressure sensor. So, im looking for a sensor which I can completely put into a vacuum chamber and measure the air pressure. Absolute pressure sensors should be able to do this as they use an internal vacuum chamber for reference. However, all the absolute sensors im looking at right now (e.g. SSCDANN015PAAA5) seem to be having 2 ports. In the data sheet/instructions one port is called the pressure port and the other port is called the reference port. I think the reference port is only used when measuring with the gage or differential option (which should also be possible with the same sensor).

So my question is, would this absolute sensor work if completely put into a vacuum chamber?
