Figure 1. Uncompensated Pressure Sensor Schematic

VOLTAGE OUTPUT VERSUS APPLIED DIFFERENTIAL PRESSURE

The differential voltage output of the sensor is directly

proportional to the differential the pressure side (P1) relative

to the vacuum side (P2). Similarly, output voltage increases

as increasing vacuum is applied to the vacuum side (P2)

relative to the pressure side (P1).

Figure 1 shows a schematic of the internal circuitry on the

stand-alone pressure sensor chip.
