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 vacu-
um is applied to the vacuum side (P2) relative to the
pressure side (P1).
NOTE: Pin 1 is noted by the notch in
the lead.
