Voltage Output vs. Applied Differential

The differential voltage output of the sensor is directly

proportional to the differential pressure applied.

The absolute sensor has a built-in reference vacuum. The

output voltage will decrease as vacuum, relative to ambient,

is drawn on the pressure (P1) side.

The output voltage of the differential or gauge sensor

increases with increasing pressure applied to the pressure

(P1) side relative to the vacuum (P2) side. Similarly, output

voltage increases as increasing vacuum is applied to the

vacuum (P2) side relative to the pressure (P1) side.

Figure 1 illustrates a block diagram of the internal circuitry

on the stand-alone pressure sensor chip.
