Stationary Condition Monitoring with Ultrasound

With the help of a fixed installation of ultrasonic transducers at a test point, short-term level changes as well as long-term trend developments can be observed. Based on changes in the ultrasonic levels, it is thus possible to make statements about the condition of the plant or the process. Furthermore, it is possible to display the level of process displays on a PC or to trigger switch events directly with the help of alarm triggers.

Turbulent flows of gases and liquids, e.g. in pipes or valves, can be monitored with permanently installed structure-borne sound probes (contact probes) as well as air-borne sound probes. In addition, structure-borne sound probes are also suitable for processes in which friction is responsible for the generation of ultrasound (e.g. bearing testing).
In combination with the stationary sensor box S-SB10 and a fixed installation of ultrasonic transducers at an inspection point, short-term level changes as well as long-term trend developments can be observed. Based on changes in ultrasonic levels, it is possible to make statements about the condition of the plant or process. For recurring measurements with recording of measurement data, the ultrasonic probe can be fixed with a magnetic base or universal magnet. For continuous monitoring or fixed mounting within a safety cover/zone, the probe is screwed on with a grub screw.
