Amplified Low Pressure Sensors

Amphenol All Sensors Corporation's amplified line of low pressure sensors is based upon a proprietary technology that tries to reduce all output offset or common mode errors. This model provides a ratiometric 4 V output with superior offset characteristics. Output offset errors due to changes in temperature, stability to warm-up, stability to long time periods, and position sensitivity are all significantly reduced when compared to conventional compensation methods. 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.
