3. The pressure-measuring device as recited in claim 2, wherein the diaphragm has a fastening segment that is connected to the force-transmitting segment via the radial segment, and the diaphragm is connected at least indirectly to the housing at the fastening segment.
4. The pressure-measuring device as recited in claim 3, wherein the diaphragm is connected to a sensor cage at the fastening segment.
5. The pressure-measuring device as recited in claim 4 wherein the diaphragm is connected at least indirectly to the housing at the radial segment.
6. The pressure-measuring device as recited in claim 5, wherein the diaphragm is connected to the sensor cage at the radial segment.
7. The pressure-measuring device as recited in claim 2, wherein one end of the radial segment goes over into an end of the force-transmitting segment.
8. The pressure-measuring device as recited in claim 2, wherein one end of the radial segment goes over into a central part of the force-transmitting segment.
9. The pressure-measuring device as recited in claim 1, wherein the force-transmitting segment has a first contact surface at which the force-transmitting element contacts the diaphragm, and a second contact surface that faces away from the first contact surface, and wherein a transmission of force to the pressure sensor takes place via the second contact surface.
10. The pressure-measuring device as recited in claim 9, wherein at least one force-transmitting element is provided that on the one hand contacts the second contact surface of the diaphragm, and on the other hand stands in effective connection with the pressure sensor.
11. The pressure-measuring device as recited in claim 1, wherein the diaphragm is fashioned by turning.
12. The pressure-measuring device as recited in claim 1, wherein the diaphragm is fashioned a metal diaphragm.
The claims below are in addition to those above.
