The Amplied line of low pressure sensor is based upon a proprietary technology to reduce all output oset or common mode errors.

This model provides a ratiometric 4-volt output with superior output oset characteristics. Output oset errors due to change in

temperature, stability to warm-up, stability to long time period, and position sensitivity are all signicantly reduced when compared to

conventional compensation methods. 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 uids 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.
