A pressure sensor, in particular suitable for use with motor vehicles, comprises a body (4) with an elastic means (8) suitable be deformed by pressure, is provided with a microelectronic circuit (9) with a resistive strain gauge. The deformable means is obtained as an integral part of the body (4). The microelectronic circuit (9) is realised using the thin-film technique, and is connected to an amplification (40) circuit comprising temperature compensation means. The invention further relates to the manufacturing process of said sensor. <IMAGE> |
