CR:110AIS Intrinsically Safe doseBadge Personal Noise Dosemeter

The CR:110AIS is a version of the CR:110A doseBadge Personal Noise Dosemter with Intrinsic Safety Certification. The CR:110AIS carries ATEX and EEx approval for both Group II (Non-Mining Applications) and Group I (Mining Applications).

The CR:110AIS has the same performance and specifications as the standard CR:110A version of the doseBadge, but has several significant differences to allow it to carry the ATEX and EEx certification. Please refer to the CR:110A doseBadge for details of the acoustic measurements provided.

What is Intrinsic Safety?

As the name suggests, Intrinsic Safety refers to equipment and wiring that is inherently safe. In other words, an Intrinsically Safe system is one with energy levels so low that they cannot cause an explosion.

The term hazardous area can be confusing. Hazardous area refers to any location with combustible materials such as gases, dusts, or fibres that might produce an ignitable mixture.

A hazardous area can be a sealed room filled with a volatile material or an area that is open to normal foot traffic, such as the area around a gasoline pump.

What is ATEX and EEx?

The ATEX Directive, named after the French “ATmosphere EXplosible”, is an EU (European Union) Directive which provides the technical requirements to be applied to equipment intended for use in potentially explosive atmospheres.

The Directive has been mandatory for all equipment of this type being sold in the European Union from the 1st July 2003.

Any equipment that is sold in the EU which is designed to be used in potentially explosive atmospheres must carry an ATEX Approval.

Please note that the CR:110AIS is the only doseBadge to be approved with Intrinsic Safety Certification and no other version of the doseBadge has been approved.
