MR Series Liquid Level Sensors now feature ATEX Approval allowing them to be listed as an intrinsically safe device. With the use of a separate intrinsically safe barrier, these MTS sensors may be used in hazardous locations where there is a potential for explosions via flammable gases, dust or vapors. The directive was adopted by the European Union and is required for use in all EU countries. The ATEX “ex” symbol carries with it approvals in the following plant designations: II1/2 G or II 2 G EEx ia IIB or EEx ia IIA T4. Liquid level gauges are also CSA, FM, JIIS and NEPSI approved.
