Relative pressure measurement recorder for determining a first pressure of a medium

Relative pressure measuring transducer for determining a first pressure of a medium, comprising

• a process adapter having a basic body,
• wherein, in a first, medium near, end region of the basic body, a pressure-sensitive process diaphragm is provided, wherein the basic body includes a first pressure transfer line, which is embodied to lead the first pressure of the medium from the process diaphragm to a pressure sensor arranged in a cavity of the basic body and to supply a first area of the pressure sensor with the first pressure of the medium,
• wherein in a second, medium far, region of the basic body, a pressure-sensitive reference pressure diaphragm is provided, which is supplied with a reference pressure present in the environment of the relative pressure measuring transducer wherein the basic body includes a second pressure transfer line, which is embodied to lead the reference pressure from the reference pressure diaphragm to the pressure sensor and to supply a second area of the pressure sensor with the reference pressure, and
• a housing adapter, which is embodied to surround the process adapter at least in the region of the reference pressure diaphragm and is connected with the process adapter in at least one connection region,
• wherein the housing adapter is arranged in such a manner relative to the process adapter that in the region of the reference pressure diaphragm an intermediate space is formed between the housing adapter and the process adapter,
• wherein there is arranged in the housing adapter a passageway, which connects the intermediate space with the environment of the relative pressure measuring transducer.
