Where the acoustic sensor technology of ds Schallsensorik is used

Many of our customers are looking for methods of non-destructive materials testing or process monitoring and discover the versatility of acoustic testing methods. Our experience shows that acoustic sensors can be deployed successfully where optical systems, for example, are not suitable due to their technical limitations and manual checks are too time-consuming and therefore not cost-effective.

Acoustic changes can reveal leaks in containers, cracks in materials such as metal, ceramics or glass, geometric defects and other quality differences in a wide range of products. Acoustic methods are used to monitor production processes and ensure the quality of final products.

In addition, the acoustic properties of production equipment and other industrial plants, often in combination with other operating parameters, provide valuable information about their condition. Building on this, acoustic sensors can also make decisive contributions to the development of predictive maintenance concepts.

The benefits of our developments are in their high processing speed, which enables acoustic analyses to be carried out in real-time and in-line, if necessary. The range of applications is broad. Acoustic sensor systems are currently used in the food processing and packaging industries, for example.

We develop individual solutions for specific applications.

Areas of application for the acoustic sensor technology of ds Schallsensorik

Areas of application

Process monitoring

The objectives of process monitoring are to improve the quality of products, increase the availability of manufacturing processes and product, machine and plant safety.

Progression in automation requires an automatic and continuous process monitoring. Structure-borne and airborne sounds can be measured relatively easy, even below and above the threshold of human perception. The evaluation of the measurements, however, requires specific knowledge. Together with our customers, we determine sensor settings to enable fact-based decisions on process interventions. Monitoring a process by means of sound sensor technology makes it possible for the customer to react in good time to deviations or faults.

Condition monitoring

The monitoring of operating parameters, e.g. speed, vibration or temperature, serves to detect faults in production equipment. In addition to the identification of causes for deviations, condition monitoring serves to replace the previously common preventive or reactive maintenance with condition-based maintenance. Compared to reactive maintenance, downtimes are minimized and, in contrast to the preventive approach, the remaining lifetimes of the components are used more effectively.

Condition-based maintenance requires continuous machine monitoring to protect the machine and its components. Wear of components causes changes in the properties of the machine structure, which have to be detected. The behaviour of the machine and its components serves as a signal source that enables the use of sound sensors.

Quality inspection

Various factors in the manufacturing process, such as fluctuations in material characteristics and process parameters or tool wear, lead to quality differences in the mass production of small parts.

Manufacturers need non-destructive, often 100 % testing of their manufactured products to avoid the delivery of defective products.

For specific products these tests can be performed by means of sound sensors. Some customers solely rely on this control method, in other cases the acoustic test is used complementary.
