This Amplified Output pressure sensor is based upon a proprietary technology to compensate all errors. This model
provides a calibrated amplified output with superior output characteristics. Output characteristics are tested at
pressure and temperature and then digitally compensated using a proprietary 3D mapping scheme. In addition the
sensor utilizes a silicon, micromachined, stress concentration enhanced structure to provide a very linear output to
measured pressure.
These calibrated and temperature compensated sensors give an accurate and stable output over a wide temperature
range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the
like.
The output of the device is ratiometric to the supply voltage over a supply voltage range of 4.5 to 5.5 volts.
