摘要： The invention relates to an ultrasonic flow sensor (110) for detecting a flow of a fluid medium in a flow tube (112). The ultrasonic flow sensor (110) comprises at least one first ultrasonic transducer (116) and at least one second ultrasonic transducer (118) and at least one wave guide (122). The wave guide (122) is designed to conduct ultrasonic waves between the at least one first ultrasonic transducer (116) and the at least one second ultrasonic transducer (118) by means of reflection on walls (126) of the wave guide (122). The wave guide (122) is further designed for the fluid medium to flow through. The ultrasonic flow sensor (110) is equipped such that the ultrasonic waves can propagate between the first ultrasonic transducer (116) and the second ultrasonic transducer (118) on at least two ultrasonic paths (124). The ultrasonic waves are reflected on the different ultrasonic paths (124) with varying frequencies. Sound energies of the ultrasonic waves transmitted on the at least two different ultrasonic paths (124) differ from each other by no more than a factor of 100.

摘要： The invention relates to an ultrasonic transducer (110) for use in a fluid medium. The ultrasonic transducer (110) comprises at least one piezoelectric transducer element (112) and at least one adjustment body (116) for promoting vibration coupling between the piezoelectric transducer element (112) and the fluid medium. The ultrasonic transducer (110) furthermore comprises at least one equalization body (118) introduced between the piezoelectric transducer element (112) and the adjustment body (116) in order to reduce thermal stresses, especially at least one intermediate layer, wherein the equalization body (118) has a thermal expansion coefficient (CTE
Zwischen ) that ranges between a thermal expansion coefficient (CTE
Piezo ) of the piezoelectric transducer element (112) and a thermal expansion coefficient (CTE
Anpass ) of the adjustment body (116). The equalization body (118) has at least one homogenous and/or macroscopicically at least substantially isotropic material, especially a material mixture.

摘要： The invention relates to a pressure sensor device (101) for an air-mass-flow measurement device for a vehicle. The pressure sensor device (101) comprises a circuit carrier, a first pressure sensor (221), which is arranged on the circuit carrier and is designed to sense a pressure and to provide a first pressure signal representing the pressure, a second pressure sensor (223), which is arranged on the circuit carrier (351) and is designed to sense the pressure and to provide a second pressure signal representing the pressure, and an evaluating apparatus (225, 227). The evaluating apparatus is arranged on the circuit carrier and has a first input interface (231) for receiving the first pressure signal, a second input interface (225) for receiving the second pressure signal, and an output interface (239) for outputting an output signal, which output signal is provided by using the first pressure signal and the second pressure signal.
