Attention:
The absolute pressure transducer setra 278 is permantly installed in both aircraft as part of the Basic Meteorology module. Additionally, the pressure transducer is installed in nose booms used for turbulence measurements.
The pressure transducer does not operate below 500 hPa.
Summary
The DPM7885 measures absolute pressure from 30-1300mbar in the temperature range of -40 to +70°C with a resolution of 5Hz.
