The anemometer (1) includes a support structure (2-7) carrying first and second resistive elements (RV, RT), the resistances of which are variable in dependence on the speed of the surrounding air and on the ambient temperature respectively. These resistive elements (RV, RT) are connected in a bridge circuit (BC) with a first pair of terminals (B, D) operatively connected to a source of supply voltage (VB) and a second pair of terminals (A, C) operatively connected to amplifying and processing circuit devices (AMP). <??>The support structure (2-7) includes first and second plates (2, 3) of an electrically insulating material arranged one above the other, essentially parallel and horizontal in operation and connected to each other by a plurality of pillars (4-7) operable to act as electrical connector elements. On its upper surface, the upper plate (2) carries the said first resistive element (RV) which is connected to a first pair of the said pillars (4, 5). The lower plate (3) carries the second resistive element (RT) on its lower surface, connected to a second pair (6, 7) of pillars. <IMAGE> |
