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).
