The MPX200 series device is a silicon piezoresistive pressure sensors provide a very
accurate and linear voltage output — directly proportional to the applied pressure. This
standard, low cost, uncompensated sensor permits manufacturers to design and add
their own external temperature compensating and signal conditioning networks.
Compensation techniques are simplified because of the predictability of Motorola’s single
element strain gauge design.

VOLTAGE OUTPUT versus APPLIED DIFFERENTIAL PRESSURE
The differential voltage output of the X–ducer is directly proportional to the differential
pressure applied.
The absolute sensor has a built–in reference vacuum. The output voltage will decrease
as vacuum, relative to ambient, is drawn on the pressure (P1) side.
The output voltage of the differential or gauge sensor increases with increasing
pressure applied to the pressure (P1) side relative to the vacuum (P2) side. Similarly,
output voltage increases as increasing vacuum is applied to the vacuum (P2) side
relative to the pressure (P1) side.
