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 the silicone gel

which isolates the die. The differential or gauge sensor is

designed to operate with positive differential pressure

applied, P1 > P2. The absolute sensor is designed for

vacuum applied to P1 side.

The Pressure (P1) side may be identified by using Table 3.
