PRESSURE (P1)/VACUUM (P2) SIDE IDENTIFICATION TABLE
Freescale designates the two sides of the pressure sensor
as the Pressure (P1) side and the Vacuum (P2) side. The
Pressure (P1) side is the side containing fluoro silicone gel
which protects the die from harsh media. The Freescale MPX
pressure sensor is designed to operate with positive
differential pressure applied, P1 > P2.
The Pressure (P1) side may be identified by using the
