VOLTAGE OUTPUT VERSUS

APPLIED DIFFERENTIAL PRESSURE

The differential voltage output of the sensor is directly

proportional to the differential pressure applied.

The output voltage of the differential or gauge sensor

increases with increasing pressure applied to the pressure

side relative to the vacuum side. Similarly, output voltage

increases as increasing vacuum is applied to the vacuum

side relative to the pressure side.
