Abstract
A measuring transducer for metrological registering of a pressure to be measured as relative pressure referenced to a reference pressure reigning in the environment of the measuring transducer, comprising: a housing; a relative pressure sensor arranged in the housing; a pressure supply, via which the pressure to be measured is fed to the relative pressure sensor, and a reference pressure supply, via which the reference pressure is fed to the relative pressure sensor. An entrance of and to the reference pressure supply communicates with an opening in a housing outer wall, on whose exterior the reference pressure acts, characterized in that a pressure equalizing element is applied in the entrance of the reference pressure supply, and the pressure equalizing element has a securement element, a filter element and a protective cap.
