WEIGHING IN ATEX AREA

 
Weighing in hazardous area
  • Hazardous areas are designated places where the presence of materials, such as gases or dust make an explosion probable if a source of ignition is introduced. Products operating in hazardous areas are required to meet stringent criteria to avoid the possibility of them becoming a source of ignition. 

  • Over many years, SCAIME has built up a wealth of experience in designing and manufacturing explosion-protected weighing equipments. 

  • Our wide selection of intrinsically safe weighing systems includes safety barriers, accessories and load cells of any capacities.

  • As an ATEX-compliant manufacturer, we ensure full safety with globally approved equipment for use in explosive dust or gas environments.
 
 
ATEX SI Intrinsic safety protection mode

Three essential elements are required for an explosion to take place:
  • Gas, mist, vapour or dust in sufficient proportions.
  • Sufficient supply of air or oxygen.
  • Source of ignition.

The hazardous areas are classified following the risk level and material type : Zones 0, 1, 2 for gas and zones 20, 21, 22 for dust. Hazardous area apparatus is classified according to the protection mode used to eliminate the explosion risk.

SCAIME provide equipements using intrinsic safety protection mode. The objet of this mode available for zones 1, 2, 21, 22 is to eliminate the source of ignition by using safety barriers.

ATEX Protection modes without safety barriers

SCAIME offers two protection modes allowing the use of weighing equipment without safety barriers :
  • Protection mode 'n' (normal) can be used in zone 2 against gas risks.
  • Protection mode 'tD' by enclosure, can be used in dust zone 21, 22.
