Patent ID: 6996490

Claim:
A sensor device (S) which includes a support structure ( 1 ) of a heat insulating material, a measuring area ( 1 d; 1 e ) being formed on one side thereof, and having a measuring device (DA, DB) disposed thereon, said measuring device including an electric heater ( 2 ) connected to the said structure ( 1 ) together with an electronic thermal flow sensor ( 3 ) and an associated electric temperature sensor ( 4 ), these being arranged above the heater ( 2 ) on the opposite side to the structure ( 1 ); the sensor device (S) also including electronic acquisition and control means (ACE) operable to control the operation of the heater ( 2 ) according to predetermined instructions and/or to receive the signals emitted by the aforesaid sensors ( 3 , 4 ); the sensor device (S) being characterised in that it comprises a second measuring area ( 1 e; 1 d ) formed on the same side of the support structure ( 1 ) as the first one ( 1 d; 1 e ) and spaced from the first measuring area ( 1 d; 1 e ), also the second measuring area ( 1 e; 1 d ) having a respective measuring device (DB; DA) disposed thereon; and a flow-speed sensor (AS) associated with the said support structure ( 1 ) and arranged on the said side of the support structure ( 1 ), for supplying during operation electrical signals which indicate the speed of air flowing in the vicinity; said flow-speed sensor (AS) being connected to said electronic acquisition and control means (ACE), which are secured to said support structure ( 1 ).
