Level Control of Cream in a Mixer with Ultrasonic Distance Sensor

In the pharmaceutical and cosmetics industries, ingredients of ointments or creams are mixed together in fully automated mixers. In order to perform the mixing process correctly and to achieve the correct consistency, the minimum and maximum fill levels must be continuously monitored. For this purpose, an ultrasonic distance sensor is installed above the mixer, which reliably detects the material regardless of color, condition or transparency. The fill level can be checked either via an analog measured value or by defining individual switching thresholds via IO-Link.
