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 silicone gel which

isolates the die from the environment. 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

following table.
