10 kPa Uncompensated

Silicon Pressure Sensors

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.
