What are ATEX Scales?

ATEX scales are specialized weighing systems designed and certified for use in potentially explosive atmospheres. The term "ATEX" is derived from the EU Directive 2014/34/EU (Atmosphères Explosibles). This regulation stipulates that only devices posing no ignition risk may be used – even under extreme conditions.

Thanks to their rugged, gas-tight construction and spark-free design, ATEX scales meet the highest standards for safety and precision. They are essential in industries working with flammable gases, vapors, or dusts.

ATEX Directive and Legal Framework

The use of explosion-protected equipment is based on the European ATEX Directive 2014/34/EU, which is binding for both manufacturers and operators. It defines the requirements for equipment and protective systems used in potentially explosive atmospheres – such as in production facilities, storage areas, or laboratories handling flammable substances.

ATEX Zone Classification

The zone classification under ATEX distinguishes areas based on how frequently and for how long explosive atmospheres can occur. Zone 0 or 20 indicates a constant presence of explosive gases or dusts. Zone 1 or 21 refers to areas where such conditions may occasionally occur during normal operation. Zone 2 or 22 are zones where explosive atmospheres are rare and only present for short periods. Devices like ATEX scales must be appropriately certified for their intended zone.

Typical Areas of Application

In the chemical and petrochemical industry, ATEX scales enable the safe weighing of highly flammable liquids and gases, such as in refineries or chemical plants. They help ensure that processes like filling or dosing can be carried out safely.

The pharmaceutical industry benefits from precise and secure weighing solutions during the production of medications, where flammable solvents and powders are common. ATEX-certified scales ensure exact dosing while complying with strict regulations.

In paint shops and cosmetics production, explosion-proof scales are essential. When mixing paints, lacquers, or other flammable substances, ATEX scales prevent any potential ignition hazard.

Mills and distilleries face an increased risk of dust explosions. ATEX-certified scales minimize this risk when processing materials like flour, sugar, or alcohol.

In hazardous materials warehouses and logistics hubs, ATEX scales ensure safe weighing and handling of flammable goods and chemicals – from incoming goods inspection to shipping.

The recycling and waste management sector requires reliable weighing solutions in environments where residues, vapors, or gases may be present. ATEX-certified scales support safe operation even under such conditions.

Advantages of ATEX Scales

Maximum Safety: ATEX scales are engineered to eliminate any potential ignition sources. Gas-tight enclosures, intrinsically safe electronics, and certified components provide reliable explosion protection.

High Precision: Despite their protective features, ATEX scales deliver accurate and repeatable results – even under challenging environmental conditions such as dust or temperature fluctuations.

Robust Materials: High-grade materials such as stainless steel ensure durability and resistance to corrosion and mechanical impact.

Diverse Designs: Whether tabletop, platform, or floor scale – there’s a suitable solution for every application. Weighing capacities range from a few grams to several tons.

Modern Interfaces: Many models feature USB, RS-232, WLAN, or Bluetooth interfaces, making them easy to integrate into existing systems and enabling convenient data transfer and documentation.

Which ATEX Scale Is Right for You?

Choosing the right ATEX scale depends on several factors. First, identify the ATEX zone in which the scale will be used. The device must be certified for that specific environment.

The type of substances being weighed – gases, vapors, or dusts – also influences the required level of protection.

Additionally, consider the maximum weighing capacity and the required accuracy. From precise laboratory analysis to robust industrial use, different applications have different needs.

Lastly, assess whether features like data transfer, mobile use, or counting functions are needed. This ensures the scale fits seamlessly into your workflow.
