Abstract

A drying module for a relative pressure measuring transducer, which has in the interior of a housing of the measuring transducer a reference pressure supply leading from a relative pressure sensor to an opening in a housing wall of the housing, and which has a connection element, whose inner space is connected via the opening with the reference pressure supply extending in the measuring transducer. The drying module comprises a module housing, which has an inner space, in which a drying means is located, and, extending through the module housing (23), a reference pressure supply, whose first end is contactable with the reference pressure via an opening of the module housing, whose second end is connectable to the reference pressure supply of the measuring transducer via a connection element of the drying module connectable with the connection element of the measuring transducer, and whose inner space in the module housing is in humidity permeable connection with the inner space containing the drying means.
