For over 60 years, the French brand Yves Rocher has been synonymous with high-quality cosmetics based on vegetable raw materials. The company is strongly committed to ecological issues and biodiversity. Even small factors such as the optimal use of raw materials play a role here. In order to avoid product losses during processing, Yves Rocher relies on automatic level control with the NCS-L level sensor when filling cosmetic cremes. With full success.
The filling systems for cosmetic creams were previously controlled manually. The filling level in the buffer tank had to be monitored by an employee and the filling process had to be stopped manually at the appropriate moment.
In order to prevent the filling pump from running dry, the process was stopped for safety reasons at an early stage, leaving important quantities of cream in the tank. This residual product was then disposed of, resulting in a significant loss of value.
With the NCS-L level sensor, the filling process is automated. Due to its special sensor shape with 18 mm length and its measuring method with an extended measuring range, the NCS-L-12/18 is particularly suitable for low-water, viscous media such as oils, syrups or even cosmetic creams. Thanks to its inline integration in the outlet pipe of the filling system, the sensor signals safely and reliably as soon as no more cream comes out of the buffer tank, thus stopping the filling process automatically.
” We were not sure whether sensor monitoring could work on this medium with viscosities up to 160 Pa·s. But Anderson-Negele’s NCS -L immediately showed perfect results without adjusting the factory setting. We save time for our employees and have been able to significantly reduce product losses. Based on the positive test results, we will now convert all filling systems to the NCS-L. “

By level measurement directly in the outlet pipe after the buffer tank, the NCS-L reports a reliable empty signal even with the viscous consistency of the cosmetic cream. Dry running of the pump, resulting in inadequately filled cream pots as well as splashes and contamination of the filling system, can thus be reliably avoided.
