BAUMER sensors designed for hygienic and wash down applications.

Baumer announced that it offers a range of photoelectric, liquid level, inductive and ultrasonic hygienic sensors designed to withstand chemicals and/or high pressure washdowns. For example, Baumer’s OADR 20 series of laser sensors provides resolutions from 5 µm and carry an IP68/IP69K rating. Baumer Series 14 hygienic photoelectric sensors are available in standard models and in a version featuring SmartReflect, a light barrier that operates without a reflector and has a sensing distance of 800 mm.

Baumer CleverLevel sensors are certified according to FDA, EHEDG, and 3A guidelines and offer 1.4404 stainless steel housings, matching PM023 weld-in boss, and PEEK plastic sensor tips. 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.

The company’s IFBR and IFRR series of inductive sensors are Ecolab-tested and EHEDG-certified. 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 suited for non-contact level measurement and control in filling machines.
