Voltage Output versus 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.
