General Description
The Amplified line of low pressure sensors are based upon a proprietary technology to reduce all output offset or common mode er-
rors. This model provides a ratiometric 4-volt output with superior output offset characteristics. Output offset errors due to change in
temperature, stability to warm-up, stability to long time period, and position sensitivity are all significantly reduced when compared to
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.
conventional compensation methods. In addition the sensor utilizes a silicon, micromachined, stress concentration enhanced structure
