Electronic measuring sensor for the registration of the atmospheric air pressure.
The primary pressure absorber is based on a silicon absolute pressure sensor item, whose function is based on the piezo-resistive effect. It is measured against a vacuum as the reference. It has an internal active temperature compensation for a wide temperature range.
The electrical measuring signal is changed into a standardized output signal in a following switched transducer electronics. The measured air pressure depends on the measuring point. For this reason, in the meteorology, all pressure indications are referred to sea level. Therefore, the air pressure sensor has to be adapted with the help of a table (barometric elevation formula) according to the setting up height.
It is supplied in a sturdy and impact-resistant plastic casing.
