Abstract
The invention relates to a pressure sensor consisting of a chip ( ) which is mounted on a support wall ( ) and which is provided with a resistance unit consisting of strip conductors and being arranged at the lower side ( ) of a substrate ( ). Said lower side faces the support wall ( ). The resistance unit is located on a thin membrane ( ). A recess ( ) is located behind said membrane. The chip ( ) is fixed on the support wall ( ) by means of an elastic intermediate layer ( ). The electrical components of the chip are protectively arranged between the substrate ( ) and the support wall ( ). 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.
