PRESSURE SENSOR |
摘要 |
The invention relates to a pressure sensor consisting of a chip (11) which i s mounted on a support wall (10) and which is provided with a resistance unit consisting of strip conductors and being arranged at the lower side (13) of a substrate (12). Said lower side faces the support wall (10). The resistance unit is located on a thin membrane (18). A recess (19) is located behind sai d membrane. The chip (11) is fixed on the support wall (10) by means of an elastic intermediate layer (26). The electrical components of the chip are protectively arranged between the substrate (12) and the support wall (10). The invention provides for an extremely flat sensor unit without additional sensor housing. Said sensor unit can even be used for measuring pressures in electrically conductive mediums.
