For technical reasons, you must apply atmospheric pressure
to the reference side of the pressure sensor.
A special ventilation unit (1) is screwed into the electronic
housing from the outside and is equipped with a PTFE filter on
the inside. Make sure that the ventilation opening is not
covered (e.g., do not paint over).
