The main function of the S-SB10 is to convert high-sampled ultrasonic signals in a usable way for downstream, low-sampled systems. Ultrasonic signals must be sampled in the range of several hundred kilohertz (kHz). Simple measurement cards or signal inputs of machine or process controls are unable to do this. If data in the ultrasonic range is to be processed, an appropriate conversion must be made. In the S-SB10, the high-frequency data is first amplified and filtered accordingly. Then, a level formation takes place, which leads to the reduction of the data stream. Finally, the level data or an alarm signal can be sent through the current output. With these signals it is now possible to feed simple measurement cards or PLC controls, which then take over the further data processing.
It is also possible to display the level of process displays or to trigger switching events directly with the help of the alarm triggers.
With the help of SONOTEC's own PC software and the USB-RS485 converter, it is simple parameterize the S-SB10. The input gain, corner frequencies of the bandpass filter (in 5 kHz steps), or averaging can be set, which is essential for commissioning and adaptation to the respective measurement task. Furthermore, alarm thresholds can be established and the type of level and its averaging can be selected.
The S-SB10 can be operated with both airborne and structure-borne sound probes. This allows versatile conditions and processes to be monitored. For example, airborne ultrasound can be used to detect turbulent flows of gases at leakages, as well as partial discharge processes at electrical installations, since both processes generate high-frequency ultrasonic signals.
