ABSTRACT:
A measuring head for a vacuum gauge. An essentially cylindrical housing encloses a measuring cell which is sealed in a vacuum tight manner against the surrounding atmosphere and is connectable with an evacuatable cavity. A measuring filament for producing an electrical signal corresponding to the pressure in the measuring cell is disposed in the measuring cell. The measuring filament is disposed approximately perpendicularly to the axial direction of the housing.
