LevelTech level sensors use innovative frequency-stroke technology to identify different media based on their resonance frequency. With two individually adjustable switching outputs, they enable reliable differentiation between foam and liquids or between two different media. For applications with frequently changing media, the adaptive trigger offers an efficient solution. The parameterization of the sensors, including filter and output functions, takes place flexibly via IO-Link. The robust, FDA-compliant stainless steel housing is easy to install even in confined spaces thanks to its compact format.
