SEMICONDUCTOR TECHNICAL DATA

0 to 50 kPa (0 to 7.25 psi)

40 mV FULL SCALE SPAN

(TYPICAL)

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 kΩ 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).
