AP4 series(Digital output)

The AP4 pressure sensor series(Digital output) is composed of a silicon piezoresistive pressure sensing chip and a signal conditioning integrated circuit. The low-level signal from the sensing chip is amplified, temperature compensated, calibrated and finally converted to digital data that is proportional with the applied pressure. The AP4 series measures gauge pressure.
