Voltage Output versus Applied Differential Pressure

The differential voltage output of the sensor is directly

proportional to the differential pressure (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).
