Fill-Level Measurement of Spices in Frozen Pizza Production via Ultrasonic Sensor

Frozen pizzas are produced and the toppings added in highly automated production facilities. Spices such as oregano are sprinkled on top of the pizzas after the toppings have been added. The spice mixture is located in an open container directly above the conveyor belt. An ultrasonic distance sensor in a hygienic stainless steel housing monitors the container to detect the exact fill level at all times so the container can be refilled in good time. The level can be continuously monitored thanks to the analog output.
