0-1 Output level switch for explosive zones +/-25º ATMI Soba Ex

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 +/-25º switching angle ensures a precise level measurement.

Advantages

• 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)

Applications

• Hazardous areas: 0, 1, 2 (gas) and 20, 21, 22 (dust).
• Waste water, sewage water, charged liquids
• Oils, mud, paint, etc.
• Aggressive liquids : acids, solvents, corrosive liquids, hydrocarbons, sea water, etc...
• Level control of multiple pumps
• Emptying / Filling function
• Overflow or dry-running protection
• High / low level alarm

Remarks

It is the customer's sole responsibility to determine whether or not its facility is located in a hazardous area. It is highly recommended to use cable hangers with our float level switches. The SOBA EX float switch must be connected through an instrinsically safe relay
