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 (http://cache.freescale.com/files/sensors/doc/data_sheet/MPX4250.pdf?fasp=1&WT_TYPE=Data%20Sheets&WT_...), 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!
