The RFID Shop offers a range of ATEX certified tags.
These tags can be safely employed on equipment that is used in potentially explosive areas.

 

hid_logo Our partner HID Global have achieved ATEX certification for their Glass Tags, IN Tags and Logi Tags according to the latest EU standards. The RFID Shop offers the entire range of these tags that can be safely used in potentially explosive environments.

What is ATEX?

ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres, ATEX Workplace Directive and ATEX Equipment Directive.

Explosive atmospheres can be caused by flammable gases, mists or vapours or by combustible dusts. If there is enough of the substance, mixed with air, the slightest source of ignition can cause an explosion.

Explosions can cause loss of life and serious injuries as well as significant damage.

What does ATEX equipment certification certify?

ATEX certification validates that our HID Global RFID tags operate without danger of directly causing or contributing to an explosion when used in flammable gas environments.  These environments include offshore drilling platforms, petrochemical plants, mines, flourmills and other process industries in which there is a mixture of gases, vapors, mists or dust in the air that can ignite at specific temperatures or under certain operating conditions. ATEX certification also validates that the company’s RFID tags perform while maintaining surface temperatures low enough to prevent the risk of ignition.

Here is The RFID Shop’s range of ATEX certified tags:

glasstags

HID Global’s Glass Tag passive contactless transponders can be easily inserted or molded into a variety of materials, to enable automated asset identification and management applications using radio frequency identification (RFID).
Manufactured with patented HID Global direct-bonding technology, these tags deliver exceptional size to performance ratios, in both low frequency and high frequency applications.
The glass enclosure ensures reliable transponder performance, despite potentially harsh conditions in finished tag production and field use.

intagIN Tag passive contactless RFID transponders deliver reliable performance in rugged conditions. Each heavy-duty IN Tag disc is highly water, chemical and shock resistant, ATEX certified for use in explosive environments and withstands peak temperatures up to 140° C.
Low frequency (LF) IN Tag discs perform well affixed to virtually any surface. They offer reliable, cost-effective tagging for near-proximity reader applications.

logitagThe HID Global Logi Tag™ family of products enables uniform companies, commercial cleaners and medical facilities to automatically track clothing, linens, rags, surgical sponges and other assets, resulting in more accurate, efficient inventory management.
Compliant with standard RFID readers and modules, Logi Tag discs are easily sewn into the hem or seam of a garment, uniform, napkin, tablecloth or runner. They may also be affixed to custodial supplies, such as mats, mops, washrags and towels.
The Logi Tag Button 162 transponder is virtually indistinguishable from ordinary buttons, and can be sewn onto clothing with standard stitching equipment and processes.
Logi Tag discs endure severe conditions while protecting data integrity.

Please remember:

Splodge-goldThe RFID Shop offers tags at conveniently low order quantities for smaller projects or for initial test applications. Large order quantities attract price reductions. Any questions? Contact us:

Understanding ATEX – What is it and what does it do?

Ever wondered what ATEX certified means? Ever tried to decipher something along the lines of: II 1G Ex ia IIC T4 Ga? Read our in-depth guide here:

What is ATEX?APEX logo

ATEX comes from the French ‘ATmosphères EXplosibles.’

It is the name commonly given to the two European Directives for controlling explosive atmospheres, ATEX Workplace Directive and ATEX Equipment Directive.

Explosive atmospheres can be caused by flammable gases, mists or vapours or by combustible dusts. If there is enough of the substance, mixed with air, the slightest source of ignition can cause an explosion.

Explosions can cause loss of life and serious injuries as well as significant damage.

What does ATEX equipment certification certify?

ATEX defines and certifies a range of Elements:

  • The device group:

I = can be used in mining
II = can be used in all other explosive areas (but not in mining)

  • A category that defines the zones the equipment can operate in.

Employers must classify areas where hazardous explosive atmospheres may occur       into zones. The classification differentiates between gas and dust-based fuels, the likelihood of an explosive atmosphere occurring and its persistence if it does:

ATEX-zones

  •  Which Atmosphere the equipment can be used in

G = Gas
D = Dust

  • Explosion Protection

Ex = ATEX certified

  • Ignition protection class:

What method the equipment uses to achieve safety. These include for example separation, special mechanical construction or limitation of energy.

Examples:

o =    Equipment components are completely submerged in oil
q =    Equipment components are completely covered with a layer of Sand, powder or quartz
p =    Equipment is pressurised to a positive pressure relative to the surrounding atmosphere           with air or an inert gas, thus the surrounding ignitable atmosphere cannot come in contact with energized parts of the apparatus. The overpressure is monitored, maintained and controlled
ia =    intrinsic safety, The development of inadmissibly high temperatures, ignition sparks and arcs are avoided due to the restriction of energy in the circuit

  • Explosion Group (data only for devices used in areas rendered potentially explosive by gas). Group I needs the most amount of energy to ignite, group IIC the least, so equipment designed for use in e.g. gas group IIB is also safe to use in IIA.:

explosion-groups

  • Temperature Class

The maximum surface temperature of a device must be less than the minimum ignition temperature of the atmosphere it is operating in. For this reason, the maximum surface temperature of equipment for use with inflammable gases, vapors or mists is specified in temperature classes. Here are the classes of the maximum permitted housing or component temperature of the operating devices:

T1 = 450°C
T2 = 300°C
T3 = 200°C
T4 = 135°C
T5 = 100°C
T6 = 85°C

  • Equipment Protection Level
Equipment Protection Levels (EPL’s) have been introduced to indicate the inherent ignition risk of equipment irrespective of the type of protection being used.

The EPL is defined by the intended use in the specified zones.
