Pressure (P1)/Vacuum (P2) side identification

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 MPX53 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.
