MPX4250GP - Absolute vs gauge pressure

Hello guys!


The MPX4250GP is supposed to be a gauge type sensor (i.e. reads pressure above barometric pressure) however I'm confused about its data sheet.


It states it reads 0-250kPa and I would assume firstly this is the reading above barometric pressure.


However, in page 4 of the data sheet (…), it says "Figure 4. Output vs Absolute Pressure" and here is where my doubts begin.


If this is a gauge type sensor why the grap/figure 4 says absolute pressure?


Does this sensor actually read 0-250kPa absolute pressure or 0-250kPa above barometric pressure?


Thank you!
