ATEX certified tilt level switches

Since July 1st 2003, all level measurement devices marketed in the European Community for hazardous environments applications must be ATEX certified according to the European Directive ATEX 94/9/EC.

It is important to know that most silos and bulk storage containers are located in hazardous areas due to the explosive nature of grains and powders they contain. Indeed, the dust emitted by certain products (corn, flour, organic powders, for example) can create explosive dust clouds.

It is important to know that it is the customer’s sole responsibility to determine before installation if its production / operation facilities are located in a hazardous area.

Please note that a non-hazardous area can become potentially explosive if this area is located close explosive environments formed by gas, vapors and combustible dust. For example, in summer, water is scarce. The scarce rain carries the pollutants along its way. As a result, grain silos and other bulk solids containers end up having high pollutant concentrations, thus creating a rather permanent potentially explosive risk.

A few examples of ATEX hazardous environments:

  • Explosive dust clouds:
    corn, flour, organic powders, …
  • Flammable gas:
    town gas, propane, butane, … 
  • Flammable vapors:
    ethanol, acetone, toluene, kerosene … 
  • Flammable liquid mists:
    aerosol, …

For this reason, it is strongly recommended not to take any risk in this domain, as the consequences could be disastrous.

To secure your facilities in a reliable way, ATMI has developed its range of SOLIBA ATEX certified tilt level switches for hazardous areas 0, 1 ,2 (gas) and 20, 21, 22 (dust).
