Hall generator pressure transducer

A pressure transducer producing an electrical signal representing pressure and capable of service in the intake air duct of an internal combustion engine, comprising a membrane or aneroid capsule constituted and held so that its center moves in dependence upon pressure applied thereto, a permanent magnet and a Hall generator provided in an integrated circuit so disposed that the movement of the center of said membrane varies the spacing between said permanent magnet and said Hall generator integrated circuit and, further, comprising the improvement that consists in that:

• said Hall generator and said permanent magnet (2) are coaxially disposed;
• and
• the Hall generator integrated circuit (3) exhibits linear relation between its output voltage (U.sub.a) and the magnetic induction (B) to which it is subject over a range of variation of said spacing between said Hall generator and said permanent magnet, produced by movement of said membrane center.
