Intrinsically Safe doseBadge Noise Dosimeter

The doseBadge is available with ATEX and EEx intrinsic safety approval for use in hazardous and explosive atmospheres. The intrinsically safe doseBadge (product code CR110AIS) has all the same acoustic functions as the standard doseBadge but comes in a gold plated brass case and with the I.S. certification.

  • ATEX and EEx approval for:
    • Group I (Mining Applications)
    • Group II (Non-Mining Applications)
  • MSHA approval
  • SABS approval for South Africa
  • Gold plated brass case
  • Same acoustic performance as standard doseBadge

Intrinsic Safety Limitations

The doseBadge noise dosimeter, mounting kit and wind shield are approved for hazardous and explosive environments. None of the other items (Reader, Charger, etc.) have I.S. approval as the doseBadge charging, calibration and start-up is carried out outside the hazardous area.

What is Intrinsic Safety?

Intrinsically Safe equipment has energy levels so low that they cannot cause an explosion. Hazardous areas are those with combustible materials such as gases, dusts, or fibres that might produce an ignitable mixture.

What is ATEX and EEx?

The ATEX Directive, (ATmosphere EXplosible), is an EU Directive that provides the technical requirements for equipment intended for use in potentially explosive and hazardous atmospheres.

The ATEX Directive became a mandatory requirement for all hazardous area equipment sold in the European Union from 2003. In addition to the technical requirements demanded by the appropriate standards for each type of produce, the Atex Directive imposes additional requirements on the certificate holder in terms of quality systems and product documentation.

Please note that the CR110AIS is the only doseBadge model with Intrinsic Safety Certification.
