  • Offer Profile
  • Our main area of business is the development, production and sale of electronic subassemblies and devices. We see ourselves as a comprehensive service-provider in that we offer our customers – primarily industrial companies – both development and production services (production planning and product fabrication) for our custom designed electronic subassemblies.

    We are able to offer our customers a complete, project-based service – from the development of a product-concept, the creation of performance specifications and the design of circuits and devices to the fabrication of various models, the planning and engineering of production and the support of the customer in the product approval and certification processes.

    As our core area of expertise, we offer engineering services in the field of electronics.
Product Portfolio
  • Applications

      • Examples for use

          • Transmission monitoring

          • Problem:
            By faulty transmission in motors or generators, caused by abrasion or imbalances, grave damages can occur.

            The use of our USS5 sound sensor for acoustic monitoring of various types of gears in machinery and equipment. Incorrect noises can be detected and processed by the sound sensor (e.g. for error messages or machine shutdowns).
          • Lighting control in underground car parks

          • Problem:
            High electricity costs by a continuous operation of the lighting system, and high costs for the installation of motion detectors.

            The use of the sound sensor ALC1 guarantees a comprehensive ensurance of the car park lighting, even on locations that are difficult to view within a parking deck. Advantages compared with motion detectors:
            • reduced installation effort
            • cost-effective operation, because larger parking areas can be monitored
            • higher energy savings because only emergency lighting is required
          • Acoustic monitoring of relays and contactors

          • Problem:
            In the production of electrical cabinets and their enclosure monitoring faulty relays trigger disturbances.

            The use of our USS5 sound sensor for acoustic control during tests of relays and contactors. The faulty relay generates noise with a certain frequency if the anchor is not activated by the correct noise. This can be detected by the sound sensor.
          • Acoustic monitoring of connectors

          • Problem:
            During the assembly of electrical cabinets or cable harnesses plug connections don´t snap properly.

            The use of our USS5 sound sensor for monitoring the production of various connectors. With the sound sensor the noise during the snap mechanism (plug-in contact into the connector) can be checked. In this way the correct operation of the connector can be ensured.
          • Acoustic leakage testing

          • Problem:
            Leakages in pipeline systems or containers.

            The use of our USS5 sound sensor for leakage testing of pipeline systems. Escaping gases out of containers and pipes cause a usable noise for the sound sensor, which can be used for monitoring and error detection.
            Special feature: Due to its high degree of protection (IP67) the sound sensor can also be used under harsh industrial conditions.
          • Monitoring of filling systems

          • Problem:
            The filling and closing of the bottles can cause breakage of glass.

            The use of our USS5 sound sensor for monitoring of filling systems. (Filling and closing of glasses and bottles) To ensure a continuous filling process the sound sensor is used for glass breakage monitoring. It recognizes, on the basis of an altered noise, the cracking of the facility of the glass container.Quality control of small components
          • Quality control of small components

          • Problem:
            Various factors in the production process, like variations of material properties and process parameters or tool abrasion trigger quality differences in the series production of small parts. So at the end of the production process good and bad parts must be separated.

            The use of our USS4 sound sensor in the quality inspection of small parts to ensure a faultless quality of parts. The sound sensor is in advance trained on certain resonant frequencies of the good parts and the necessary control parameters for the sound check are set.
            • After stimulating the parts from the outside, the produced sounds are compared with the trained sound patterns. So the faulty parts can be separated directly from the faultless parts.
            • max. 15 different sounds with 30 possible frequencies can be monitored simultaneously
            • modulation of the faulty parts can be done via two switching outputs
          • Monitoring of agricultural machinery

          • Problem:
            When obtaining harvest stones, which can then in processing destroy machinery and equipment, are also often transported (e.g. in sugar beet extraction)

            The use of our USS5 sound sensor for monitoring of harvested crop in sugar beet extraction. By the sound sensor a continuous separation of sugar beets from carried stones is guaranteed for further utilization of the beets in biogas plants.

            • Why acoustic sensors?

            • Certainly, not everyone needs an acoustic sensor.
              For everyone else: the sensors of the dsound®series

              Equipment for industrial quality testing is often expensive, difficult to install, requires frequent and often difficult maintenance, and is not applicable in many areas. The dsound® USS4 "hears" small changes of sound emitted by small parts or glass containers. Even the tiniest faults, like cracks, inclusions or geometry deviations are reliably detected despite intense ambient noise. Using the means of sound detection, high enclosure class and the compact housing of the sensor; quality testing is now possible in areas where other methods, like for example cameras fail. You will be amazed by the intelligent USS4.

              A deviation from the usual sounds of a production process is often the first sign of an operational fault such as ripping material, breaking tools or bursting pressure hoses. With the help of the dsound® USS5, machines and processes can be reliably monitored acoustically. Additionally, assessments of valve- or relay states or snapped-in parts in assembly are viable. If the need arises, the USS5 is able to intervene in the event of unwanted ignitions or emerging leakage. The USS5 provides security to critical processes.

                                    • The first acoustic lighting controller for parking garages,  stairways and hallways.

                                      Many people are familiar with the following problem:

                                      Compliance with statutory minimum lighting for public transport routes and corridors causes high power requirements. Because of that energy costs are one of the biggest cost drivers.
                                      An alternative, temporary control lighting system via motion detector due to their short range is very expensiveresepectively complex and is thereby hardly able to generate savings. 

                                      With the dsound ® ALC1 there is now the first lighting control, that achieves maximum energy savings and accounts the special needs of parking and garage operators despite the high safety standards.


                                      The advantages are obvious:
                                      • up to 80% less energy costs
                                      • range up to 1500 qm (with one sensor!)
                                      • high security due to individual lighting control
                                      • simple configuration via remote control

                                      A development of our company is the Windows Panel PC with UCT1 4.8“ touch
                                      display. This serves both as a front end for our USS4 and USS5 sound sensors of
                                      the dsound® series and the control of machines and systems in production
                                      In connection with the dsound®-sound sensors an extensibility of sound detection
                                      systems up to retraining in batch change is possible. Thus, a flexible adjustment of
                                      the sound check to changing parameters is guaranteed.

                                      Because of its Windows operating system, the panel PC UCT1 with its compact
                                      dimensions and its rail mounting is available for a wide range of applications.
