Technical functionality of ultrasonic sensors in industrial electronics
Ultrasonic sensors essentially consist of a piezoelectric transducer that converts electrical signals into mechanical vibrations. These generate ultrasonic waves that hit an object and are reflected. The sensor measures the time between transmission and reception of the echo in order to calculate precise distances or fill levels.
Depending on the application, closed or open designs are used: for example in distance meters, flow or level sensors. In the electronics industry, these sensors are often used for the non-contact detection of objects, liquids or gas flows. Audiowell offers variants with a long range, temperature resistance and powerful signal processing, which are distributed by Rotima.

Ultrasonic sensors in vehicle technology and flow measurement technology
Ultrasonic sensors are used in a wide range of industrial and technical applications where precise, non-contact measurement methods are required. In automation technology, they detect distances, fill levels and movements - for example for detecting the position of workpieces, for material monitoring or for safety functions on machines.
In vehicle technology, they are used as reversing sensors, in parking aids or for detecting the fill level of liquid containers, for example in AdBlue systems. They are also indispensable in flow technology: ultrasonic flow sensors precisely measure the flow rate of liquids or gases, without moving parts and with minimal pressure loss.
Thanks to the cooperation with Audiowell, Rotima offers specialized sensor solutions: from high-temperature and underwater variants to modules with pipe integration or particularly compact designs. This variety makes ultrasonic sensors an important component in modern electronic systems with the highest demands on precision and reliability.
