Patent ID: 7509866

Claim:
A pressure sensor with a carrier ( 2 ), which in an inner region comprises a membrane ( 4 ) on which four first measurement elements (R 1âˆ’ , R 1+ ) for detecting a pressure impingement of the membrane ( 4 ) are arranged, wherein additionally, four second measurement elements (R 3âˆ’ , R 3+ ) for detecting a pressure impingement of the membrane ( 4 ) are arranged on the membrane, wherein the first measurement elements (R 1âˆ’ , R 1+ ) are spaced apart a first distance from the edge of the membrane and the second measurement elements (R 3âˆ’ , R 3+ ) are spaced apart a second distance from the edge of the membrane, the first and second distances being different, and wherein the first and second measurement elements are connected to one another in a bridge circuit so that the output signals of the first and the second measurement elements (R 1âˆ’ , R 1+ , R 3+ ) detect a differential pressure acting on the membrane ( 4 ), and thereby compensate the influence of the system pressure acting on both sides of the membrane ( 4 ).
