General Description

The Amplified line of low pressure sensors is based upon a proprietary technology to reduce all output offset or

common mode errors. 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 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 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.
