Humidity measuring device

摘要

The invention relates to a humidity measuring device comprising a humidity measuring sensor (2) comprising a first surface (24) forming an air-filled chamber (4), the air-filled chamber (4) comprising the humidity measuring sensor (2) inside the chamber (4), the first surface (24) comprising a first barrier part (9) being permeable to air and water vapour, and the first barrier part (9) forming a flow path between inside the air-filled chamber (4) and outside the first surface (24). A second surface (25) arranged to surround the first barrier part (9), the second surface (25) comprising a second barrier part (8) being permeable to air and water vapour, and the second barrier part (8) forming a flow path between inside the second surface (25) and outside the second surface (25). The first barrier part (9) and the second barrier part (8) arranged successively to form a flow path between inside the air-filled chamber (4) and outside the second surface (25), an air gap (10) between the first barrier part (9) and the second barrier part (8) providing a capillary break.
