Studying the datasheet, in my interpretation, this measures the pressure at the inlet P1 relative to the atmospheric pressure, since P2 is not sealed under vacuum. However, on adelivery side, it is referred to as an "absolute" pressure measuring, which would mean a measurement relative to 0Pa. How to interpret it?
Hi Sandor,
Your interpretation is correct, the MPXV5004GC6U is a positive gauge pressure sensor measuring the positive pressure on the P1 side relative to the ambient pressure on the P2 side.
Best regards,
