SEMICONDUCTOR TECHNICAL DATA  
The MPX100 series device is a silicon piezoresistive pressure sensor providing 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.
