PRESSURE (P1)/VACUUM (P2) SIDE IDENTIFICATION TABLE

The two sides of the pressure sensor are designated 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:
