Mehrkanalige Ultraschall-Messeinrichtung

DE 10354473 A UPAB: 20050818 NOVELTY - The device has a control unit (1) with measuring channels for connection of ultrasonic sensors (2) to transmit and receive generated low frequency ultrasonic signals. The unit (1) has an analyzing unit with a transmitter to control the sensors to evaluate the reception of the signals of the sensors. The unit (1) measures high frequency body impact signals to measure running time in gaseous medium. DETAILED DESCRIPTION - The ultrasonic sensors are arranged in an ultrasound transducer and sense a task e.g. impact sound measurement. USE - Used for measuring a task e.g. distance measurement, liquid level measurement and impact sound measurement, in a motor vehicle. ADVANTAGE - The unit measures high frequency body impact signals to measure running time in gaseous medium, thus ascertaining the level of fuel through term measurement in the gaseous medium, detecting a distance between objects through operating time measurement in air, and recognizing damages to the vehicle component. The ultrasonic sensors can sense the measuring task and can be simply arranged in the ultrasound transducer without having to start another control electronics for each measuring task
