Pressure sensor comprising a hall-effect gaussmeter is incorporated in circuit integrated

摘要

P a.l' invention relates to a pressure sensor comprising a membrane or a box a membrane 1 is subjected to the pressure and which travels as a function of this pressure by varying the distance between a permanent magnet 2 and a list of the hall a circuit 3 has integrated. / p & & p & characterizes sensor is incorporated in which the hall-effect gaussmeter 3 comprises a linear relationship between its output voltage ua and the magnetic induction b and in that the list of the hall-effect gaussmeter and the permanent magnet 2 are disposed coaxially. / p & & p & c.l' invention is applicable in particular for determining the pressure of the intake air of an internal combustion engine. / p
