Pressure Equalizing Element

The invention relates to a measuring transducer (1) for metrological registering of a pressure to be measured (p) as relative pressure (pR) referenced to a reference pressure (pref) reigning in the environment of the measuring transducer (1), comprising a housing (2), a relative pressure sensor (3) arranged in the housing (2), a pressure supply, via which the pressure to be measured (p) is fed to the relative pressure sensor (3), and a reference pressure supply (5), via which the reference pressure (pref) is fed to the relative pressure sensor (3), wherein an entrance of and to the reference pressure supply (5) communicates with an opening in a housing outer wall (2a), on whose exterior the reference pressure (pref) acts, characterized in that a pressure equalizing element (6) is applied in the entrance of the reference pressure supply (5), and the pressure equalizing element (6) has a securement element (7), a filter element (8) and a protective cap (9).
