Product Specification

Barometric Pressure Sensors
600 to 1,100 mbar Barometric Pressure

AXCA Series Barometric Amplified Pressure Sensors General Description
These Barometric pressure sensors are based upon a proprietary package technology to reduce errors. This model provides a fixed 4-volt output with superior output characteristics. The sensor housing has been designed specifically to reduce package induced parasitic stress and strain. In addition the sensor utilizes a silicon, micromachined (MEMS) structure to provide a very linear output to measured pressure. The sensor embodies a vacuum reference.

These calibrated and temperature compensated sensors give an accurate and stable output over a wide temperature range. Each sensor is internally compensated using an ASIC compensation technique. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like.

AXCA Series Barometric Amplified Pressure Sensors Options
• Ratiometric Output
