Patent ID: 7946178

Claim:
Vacuum measuring cell device comprising a diaphragm vacuum measuring cell ( 8 ) with a diaphragm ( 2 ) acting as a pressure transducer, wherein on one side of the diaphragm ( 2 ) spaced apart from it a first housing plate ( 1 ) is disposed under sealing in a margin region of the diaphragm using a bonding, such that a reference vacuum volume is formed between them, and that on an other side of the diaphragm ( 2 ) spaced apart from it a second housing plate ( 4 ) is disposed under sealing in the margin region using a bonding, such that a measuring vacuum volume ( 9 ) is formed between them, and that the second housing plate ( 4 ) includes an opening on which connection means ( 5 , 6 ) are disposed under sealing using a bonding for the communicating connection of the measuring vacuum volume ( 9 ) with the medium to be measured, the measuring cell device including electronic circuitry ( 34 ) which is electrically connected with the diaphragm vacuum measuring cell ( 8 ), and the measuring cell device includes a heating configuration ( 20 , 21 ) for heating the diaphragm vacuum measuring cell ( 8 ) to a predeterminable temperature value, and wherein the heating configuration ( 20 , 21 ) substantially completely encompasses the diaphragm vacuum measuring cell ( 8 ) such that it forms a thermal container ( 20 ), wherein this container forms a thermal body ( 20 a ) in the proximity of the connection means ( 5 , 6 ) through which connection means ( 6 ) are carried and herein are thermally contacted at least in subregions by the thermal body ( 20 a ), and that the thermal body ( 20 a ) includes a heat source ( 21 ), wherein the thermal container ( 20 ) is substantially completely enclosed by an insulation jacket ( 22 ).
