Wide range of sensors for food and packaging machines

With its broad sensor portfolio featuring many different technologies, Baumer is able to meet the high requirements associated with producing, processing and packaging food products. Photoelectric, inductive and ultrasonic sensors provide valuable support in the diverse applications and are characterized by their chemical resistance and hygienic or washdown design.

For example, Baumer offers the UNAR 18 series of ultrasonic sensors in different versions. With its stainless steel housing and the chemical resistance that its parylene coating provides, this sensor is an ideal choice for the food industry. The switching version enables the sensor to detect the presence of cups or bottles, whereas the measuring version of the UNAR 18 is particularly well-suited for the contactless level control in filling machines.

For volume measurement, such as used in meat and cheese processing, Baumer provides the OADR 20 series of laser sensors. The sensor in the stainless steel housing features a high degree of accuracy, more specifically a resolution from 5 µm. Moreover, the design with Baumer's unique proTect+ impermeability concept ensures that the sensors comply with protection class IP 68/IP 69K even after many temperature cycles.

The IFBR and IFRR series of inductive sensors are available in the hygienic and washdown design. That means that these products feature smooth, continuous or sealed surfaces, corrosion-resistant materials as well as flush and hygienic connections. At the same time, the sensor is able to withstand the ever more frequent and intense cleaning and disinfection cycles. The Ecolab-tested and EHEDG-certified inductive sensors are particularly well-suited for presence detection in food processing machinery.

Series 14 photoelectric sensors, which are used to detect food or packages on convey belts, feature the hygienic and washdown design as well. This feature is also present in a version of the SmartReflectTM, an award-winning light barrier without a reflector that has a sensing distance of 800 mm.
