Baumer''s multi-purpose LBFS level switch is now available in three different ATEX configurations which enable safe level detection in explosive gaseous and dusty atmospheres. Baumer uses a highly specialized protective design for the ATEX versions of the LBFS. Thanks to this, versions Ex ta for dust (zones 20, 21, and 22) and Ex nA for gas (zone 2) can be used without a Zener barrier because the housing itself already provides all the necessary protection. This is very cost-effective because usually all sensors for hazardous areas require a Zener barrier. The ATEX certifications cover zones 0, 1 and 2 (gas) as well as zones 20, 21 and 22 (dust). Quick installation and ease of use is also ensured for version Ex ia for gas (zones 0 and 1).
