The new MPX7050 series pressure sensor incorporates all the innovative features of
Motorola’s MPX2000 series family including the patented, single piezoresistive strain
gauge (X–ducer) and on–chip temperature compensation and calibration. In addition, the
MPX7050 series has a high input impedance of typically 10 k
for those portable, low
power and battery–operated applications. This device is suitable for those systems in
which users must have a dependable, accurate pressure sensor that will not consume
significant power. The MPX7050 series device is a logical and economical choice for
applications such as portable medical instrumentation, and remote sensing systems with
4–20 mAmp transmission.

VOLTAGE OUTPUT versus APPLIED DIFFERENTIAL PRESSURE
The differential voltage output of the X–ducer 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 (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).
