Explosion protection made by MOLLET
Level measurement in explosive atmospheres requires know-how provided by MOLLET Before level measurement in a potentially explosive atmosphere could be operated the potential risk of explosion has to be evaluated in a risk assessment. Part of this is the evaluation of the formation of explosive atmospheres. This will occur only, if atmospheric oxygen in sufficient quantities, an effective ignition source and combustible material appear at the same place. Combustible material could be flammable dust, gas and hybrid mixtures. Flammable dust means dust, fibers or suspended particles which can burn or glow in the air and could explode in atmospheric conditions. Products like coal dust, aluminium powder, powdered sugar, wheat flour or dust caused by grain are included. These dusts occur permanently by transportation, filling and discharging of bulk solids and are often been spread over the entire premises.
Depending on the danger of explosion the premises is classified into different potentially explosive atmospheres according to the ATEX guidelines.
