Maximum range with outstanding precision thanks to focused ultrasonic transducers
Focused airborne ultrasonic transducers play a central role in distance measurement and level measurement as they enable precise and non-contact measurements to be made in a wide range of industries. These transducers use high-frequency ultrasonic waves that are transmitted through the air and reflected by objects or filling media. By measuring the time of flight of the sound signal, the distance or level can be accurately determined. This technology is widely used in the manufacturing, logistics, automotive, chemical and food industries.
Distance measurement
In distance measurement, ultrasonic transducers are used to determine distances between the sensor and a target object. Thanks to their ability to direct and focus sound waves in a targeted manner, they can perform precise measurements even over long distances. A significant advantage over other technologies such as infrared or laser sensors is that ultrasonic waves also work reliably in dusty, harsh or damp environments. This is particularly useful in industrial applications, such as robot navigation, where obstacles need to be detected and distances precisely determined.
Ultrasonic distance measurement is also used in automation, e.g. for positioning machines or workpieces on production lines. In warehouses and logistics centers, customers use these transducers to detect obstacles or automatically determine distances in order to improve the efficiency of transport systems and autonomous vehicles.
Level measurement
Another important area of application for focused ultrasonic transducers is level measurement in tanks, silos or containers. Here, the ultrasonic waves are sent down into the container and reflected by the surface of the filling medium (e.g. liquid, powder or granulate). The transit time of the returning signal provides information about the fill level. Ultrasonic level gauges are particularly popular in the chemical industry, food processing and agriculture, as they are non-invasive and do not require direct contact with the material to be measured.
One advantage of this technology is its high flexibility. Ultrasonic level gauges can be used in a wide variety of containers, regardless of the shape or material of the container. They are also resistant to dust, dirt and temperature fluctuations, which makes them ideal for demanding industrial environments.
To summarize, airborne ultrasonic transducers are indispensable tools for distance and level measurement. Their versatility, precision and durability make them an ideal solution for a wide range of industrial applications.
