Abstract
An air-mass sensor having an air mass sensor module provided with two temperature sensors ( ) and two heat sensors ( ) which are incorporated into two separately acting bridges (I, II) whose bridge output signals (U , U , U ) are supplied to a microprocessor ( ) incorporated on a common support with the air-mass sensor module. The microprocessor ( ) is calibrated such that crude bridge signals (U , U , U ) measured in a base mode are inscribed in support places (x , x , x ) of support place tables (St , St ). A customer characteristic curve is filed in the form of measurement points (m , m , m ) in the support place tables (St , St ) and are utilized to adjust the crude bridge signals.
