The MPXM2102 device is a silicon piezoresistive pressure sensors providing a highly  
accurate and linear voltage output — directly proportional to the applied pressure. The  
sensor is a single, monolithic silicon diaphragm with the strain gauge and a thin–film  
resistor network integrated on–chip. The chip is laser trimmed for precise span and offset  
calibration and temperature compensation.

Figure 1. Temperature Compensated Pressure Sensor Schematic  
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).  
Preferred devices are Motorola recommended choices for future use and best overall value.
