Baumer Hygienic Sensors for Food Processing and Packaging

To meet the demanding requirements associated with processing and packaging food products, Baumer offers a broad portfolio of photoelectric, liquid level, inductive, and ultrasonic hygienic sensors designed to withstand chemicals and/or high pressure washdowns.

For volume measurement in meat and cheese processing, Baumer’s OADR 20 series of laser sensors provides a high degree of accuracy and resolutions from 5 µm. Encased in a stainless steel housing, these sensors feature Baumer’s unique proTect+ impermeability design to ensure compliance with protection class IP68/IP69K, even after repeated temperature cycles.

Used to detect food items or packages on conveyor belts, Baumer Series 14 hygienic photoelectric sensors are available in standard models and in a version featuring SmartReflect, an award-winning light barrier that operates without a reflector and has a sensing distance of 800 mm.

In liquid level measurement applications, Baumer CleverLevel sensors are outstanding alternatives to vibrating fork switches. Certified according to FDA, EHEDG, and 3A guidelines, these sensors offer 1.4404 stainless steel housings, matching PM023 weld-in boss, and PEEK plastic sensor tips that protrude only 18 millimeters into the container or tube to avoid flow blockage. LBFS versions feature standard output configurations and operate from -40 to +115°C, while LFFS versions withstand operating process temperatures from -40 to +200°C and are programmable using a separately ordered Flexprogrammer.

For presence detection in food processing machinery, the Baumer IFBR and IFRR series of inductive sensors feature corrosion-resistant materials, flush connections and smooth, continuous or sealed surfaces. The sensors withstand increasingly frequent and intense cleaning and disinfection cycles, and are Ecolab-tested and EHEDG-certified.

Designed to handle challenging food packaging applications, Baumer’s UNAR 18 series of ultrasonic sensors feature stainless steel housings with a parylene coating for increased chemical resistance. The switching output version enables the sensor to detect the presence of items such as cups or bottles, while the measuring version of the UNAR 18 is well-suited for non-contact level measurement and control in filling machines.
