KSB Sonolyzer
Read full descriptionHide full description
The first App that hears if you save energy. KSB Sonolyzer enables you to appraise the efficiency or inefficiency of pumps and other rotating equipment by simply listening. You enter four parameters which you can find on the type plate of the machine and hold your mobile device for 20 seconds close to the fan of the induction motor operated with constant supply voltage and frequency. Sonolyzer captures the operational noise with the inbuilt microphone and analyses the noise spectrum within seconds. The results are displayed afterwards on your device display, e.g. that pump and motor are operated in partial load. You can request advice based on your individual analysis, and your locally responsible KSB contact can connect seamlessly to your analysis.
