Abstract: The invention relates to a vacuum measuring cell device comprising a vacuum membrane measuring cell (8) having a connecting means (5, 6) arranged thereon for a communicating connection to the medium to be measured, an electronic system (34), which is electrically connected to the vacuum membrane measuring cell (8), and also comprising a heating arrangement (20, 21) for heating the vacuum membrane measuring cell (8) to a predefinable temperature value, wherein the heating arrangement (20, 21) substantially encloses the entire vacuum membrane measuring cell (8) such that said cell forms a thermal container (20). Said container constitutes a thermal body (20a) in the area of the connecting means (5, 6) and connecting means (6) are guided through it, the connecting means thereby being thermally contacted at least in some areas by the thermal body. The thermal container (20a) comprises a heating source (21) for the heating thereof.

Abstract: A shield arrangement for a vacuum measuring cell has a tubular shield housing encompassing a shield and an exit port for connection to a vacuum measuring cell and a connection opening for the object space to be measured. The shield is between the two openings and is implemented as a screw shield with spiral convolutions, its thread flange in the outer diameter being in contact on the inner wall of the shield housing such that a gas throughflow between the outer diameter of the thread flange and the inner wall is inhibited and is substantially forced into the spiral thread flight, and the exit port is on one side of the tubular section and the connection opening is on the other, opposite side and the screw shield is implemented such that in the axial line of vision the shield arrangement between the two openings is optically tight.
