Capacitive sensors track level for all types of media

The Advanced SmartLevel Sensor (photo) combines standard capacitance-sensing technology with patented SmartLevel technology, which enables it to reliably sense solids, granulates and highly conductive acids and bases, says the company. It is housed in 316 stainless steel to withstand aggressive environments. The polyether ether ketone (PEEK) housing on the sensing nose provides protection against sticky and adhesive materials. It can withstand use in an autoclave for up to one hour, and when used with proper mounting accessories, the sensor can be used in hygienic applications. It can be easily integrated into control systems (discrete-output and IO-Link versions are available). This sensor provides excellent compensation against foam, film and material buildup that cause false triggers in competing sensors, according to the manufacturer. — Balluff GmbH, Neuhausen, Germany
