Optimized cleaning for maximum product quality

thyssenkrupp measures cleaner concentrations with Teqwave I

Teqwave I from Endress+Hauser provides thyssenkrupp Presta AG with a new reliable solution for monitoring cleaning media in its spray and flood part cleaning machines. Teqwave uses special sound waves to create an acoustic “fingerprint” of the high-quality cleaning media being used. This enables Teqwave to detect their concentration in cleaning baths continuously and with high precision.

The result

  • Safeguarded process quality thanks to real-time measurement with high accuracy

  • Quick reaction through immediate readjustment in case of changes in the cleaner concentration

  • Minimum risk of errors, for example, as caused by writing down measured concentration values by hand

The challenge

The concentration of the cleaning medium used to be measured once a week by a specialist using an elaborate titration method. This process included documenting the measured concentration values, which are crucial in maintaining the desired process stability. Both the measurements and the documentation were very time-consuming and made intensive use of consumables. In addition, the process of reading out measured values manually during titration and documenting them proved to be very error prone.

Our solution

With the installation of Teqwave I , the cleaning processes at thyssenkrupp can be carried out safely, more efficiently, and more cost-effectively:

  • Continuous monitoring of density, concentration and temperature of the cleaning medium in real time

  • Optional monitoring of a second concentration

  • Direct on-site measurement in the plant – no time-consuming sampling for laboratory measurements

  • Reliable, maintenance-free and long-term stable measuring technique with high accuracy
