Silicon Pressure Sensors
MPX12 SERIES
The MPX12 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 Freescale's single element strain gauge design.
