PCT No. PCT/NL96/00212 Sec. 371 Date Apr. 27, 1998 Sec. 102(e) Date Apr. 27, 1998 PCT Filed May 29, 1996 PCT Pub. No. WO96/38731 PCT Pub. Date Dec. 5, 1996The invention provides a device for determining the direction and speed of an air flow, comprising a chip which is provided with two mutually perpendicularly positioned pairs of measuring circuits placed at a distance opposite each other, optionally four heating elements in positions coinciding with the measuring circuits and a control circuit, which chip is fixed onto a substrate, characterized in that the mounting between chip and substrate is substantially homogeneous and preferably effected by gluing. The chip is for instance accommodated in a housing of conducting material. The device can contain in addition to the measuring chip a reference chip without heating elements which is embodied in substantially identical manner and which is shielded from the measuring chip by an insulator. |
