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 fluorosilicone gel

which protects the die from harsh media. The MPX pressure

sensor is designed to operate with positive differential

pressure applied, P1 > P2.

The Pressure (P1) side may be identified by using the

table below:
