Silicon Pressure Sensors

The MPXM2053 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 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 Freescale Semiconductor recommended choices for future use and best overall value.
