Figure 1. Uncompensated Pressure Sensor Schematic
VOLTAGE OUTPUT VERSUS APPLIED DIFFERENTIAL PRESSURE
The output voltage of the differential or gauge sensor
increases with increasing pressure applied to 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).
