High performance and high accuracy enable the use of this pressure sensor in many applications including differential pressure measurements. Standard 2nd order temperature and pressure compensation provide 0.5% FS total error from 0°C to 70°C. A single power supply from 2.7V to 5.5V, customized compensated pressure ranges, standard digital outputs, one wire interfaces, or analog voltage outputs provide OEM users with maximum flexibility for any application with dry air or non-corrosive gases.
Pressure ports with various options can accept standard pneumatic tubes or can be customized for integration into end customer housing with straight pressure ports. Different pressure ranges are available from 0-1 mbar up to 0-10 bar.
