Patent ID: 6845656

Claim:
A semiconductor pressure sensor for sensing pressure of an interior of an intake pipe of an internal combustion engine of a motor vehicle, said pressure sensor comprising: a sensor body adapted to be attached on a wall section of said intake pipe, such that a pressure inlet port of said sensor body faces the interior of said intake pipe; and a semiconductor gauge for sensing said pressure, said gauge being located so as to be exposed directly in said pressure inlet port of said sensor body; wherein said sensor body is a two-piece structure, which includes a sensor holder and a cylindrical cap; said sensor holder includes a semiconductor gauge housing section, a circuit substrate housing section for holding a circuit substrate mounted with electronic circuitry, and a connector; said cylindrical cap has said semiconductor gauge housing section and said circuit substrate housing section inserted therein, with said connector extending out thereof; and said pressure inlet port is formed by a shape of said semiconductor gauge housing section of said sensor holder and an inside of said cap.
