Low Pressure & Digital Output
Semiconductor Pressure Sensor
AL4 Series
Description
The AL4 pressure sensor series is a low pressure and
digital output pressure sensor. It 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.
