temperature sensor when the measuring device is in the assembled state the temperature sensor 36 is situated laterally beside the bypass channel 16 and downstream of the electronics housing 22 as illustrated in fig3 the electronics housing 22 is provided with the contact pins 38 which when inserted establish an electrical connection between evaluation electronics 48 and the connector element 24 fig4 shows the bypass element 16 with its opening 14 for the bypass channel the bypass channel has a first section for the inflowing air and a second section that is connected to the first section by way of a deflection section in the area of the deflection section the first and second sections are separated from one another by a wall 40 the sensor carriers bearing the sensors 18 and 20 are disposed in the bypass channel the channel element 16 has a flange 42 running around it onto which a housing base element 44 is placed the housing base element 44 is provided with the contact pins 38 the contact pins 38 project from a pedestal 46 disposed in the base element 44 is the flat electronics substrate 48 that evaluates the measurement signals from the sensors 18 and 20 and forwards its results by way of the contact.
