The SOBA EX is an ATEX certified float switch ideal for hazardous environments 0, 1, 2 (gas) and 20, 21, 22 (dust). As the liquid level reaches the float, the mechanical switch inside the float will tilt, thus closing or opening a circuit connected to an electrical panel. The SOBA EX is equipped with an external adjustable resin ballast, and its +/-25? switching angle ensures a precise level measurement.
Double waterproof thanks to its HR HY (High Resistance) housing No maintenance needed, thanks to its biconical shape that avoids any clogging Easy to install, easy to use Ecological float switch (no mercury, no lead)
