Silicon Pressure Sensors

The MPX2102/MPXV2102G series device is a silicon piezoresistive pressure sensor

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.

VOLTAGE OUTPUT versus

APPLIED DIFFERENTIAL PRESSURE

The differential voltage output of the sensor is

directly proportional to the differential pressure applied.

The absolute sensor has a built–in reference vacu-

um. 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 vacu-

um is applied to the vacuum (P2) side relative to the

pressure (P1) side.

Preferred devices are Motorola recommended choices for future use

and best overall value.
