ATEX Scales

ATEX Scales

ATEX scales – precise and safe weighing technology for areas at risk of explosion

Precision scales with explosion protection – safety in sensitive working environments

ATEX scales are specially developed industrial scales for use in areas at risk of explosion. They meet the strict requirements of the ATEX Directive 2014/34/EU and offer the highest level of safety when weighing materials in industries such as the chemical and pharmaceutical industries, food production and paint shops. These scales are designed to work reliably in ATEX zones 1/2 and 21/22 and to ensure both precise measurement results and explosion protection.

Why choose an ATEX scale? – The most important advantages at a glance

ATEX-certified scales offer essential advantages for companies operating in potentially explosive atmospheres. The most important features are:

1. Maximum safety through explosion protection

ATEX scales are certified according to the legal requirements for explosion-prone work areas. The risk of ignition is minimized by special protective mechanisms, such as stainless steel housings, gas-tight seals and special cable connections.

2. Exact measurement results in all areas

Thanks to the latest weighing technology, these highly precise Ex scales provide reliable measurement results – even under challenging conditions. Whether as a precision scale, platform scale or counting scale, the exact measurement remains constant.

3. Robust construction and durable materials

ATEX scales are made of high-quality stainless steel to prevent corrosion and mechanical damage. This makes them ideal for long-term use in demanding environments.

4. Versatile

Whether in a paint shop, chemical production or food processing, ATEX scales are designed for a wide range of applications. Depending on the model, they can be used for various industrial weighing processes, from verifiable ATEX scales to scales with wireless systems.

5. Expandable functions and accessories

Many ATEX scales are equipped with interfaces such as RS232, WLAN or Bluetooth to enable easy data transfer. They can also be expanded with printers, software solutions and special displays.

Areas of application for ATEX scales – where are they used?

ATEX scales are used in a wide range of industries where there is a high risk of explosion. The main areas of application include:

1. Chemical and pharmaceutical industry

In chemical and pharmaceutical companies, handling of flammable liquids and powders is common practice. Ex-protected precision scales ensure safe and accurate measurement results while excluding any ignition source.

2. Food production and milling

Dust explosions pose a major risk in food processing, especially in mills, bakeries or factories with fine flour and sugar particles. ATEX-compliant industrial scales minimize this risk.

3. Paint shops and coating plants

Solvents and paint vapors in paint shops require special explosion-proof scales that enable safe weighing of paints and chemicals.

4. Petrochemical industry and gas stations

ATEX scales are certified for use in environments where gases and flammable liquids are present. In refineries or tank farms, floor scales or verifiable ATEX scales are used to ensure accurate measurements.

5. Waste management and recycling industry

In the waste disposal and recycling industry, there is often a risk of flammable dusts and gases. Here, platform scales and industrial scales with ATEX certification ensure safe working.

The right ATEX scale for your application

When selecting the appropriate ATEX scale, various factors should be considered:

  • Area of application: Depending on the industry, a platform scale, counting scale or floor scale may be the best choice.
  • Protection class: ATEX zones 1/2 or 21/22 define the required explosion protection.
  • Accuracy: High-precision models are essential for certain applications.
  • Function extensions: Interfaces, printers or external displays can be important.

What do the different ATEX zones and ATEX protection classes mean?

The ATEX protection classes define how often and in what form explosive atmospheres can occur:

Zone 1:
Areas in which an explosive atmosphere caused by gases, vapours or mists may occasionally occur during normal operation.

Zone 2:
Areas in which an explosive atmosphere caused by gases, vapours or mists is not likely to occur in normal operation but, if it does occur, will persist for a short period only.


Zone 21:

Areas in which an explosive atmosphere caused by dusts may occasionally occur during normal operation.

Zone 22:

Areas in which an explosive atmosphere caused by dusts is not likely to occur in normal operation but, if it does occur, will persist for a short period only.

The zones differ mainly in the frequency of occurrence (occasional vs. infrequent or short-term) and the type of explosive atmosphere (gases/vapours/mists vs. dusts).

Frequently Asked Questions

Frequently Asked Questions about ATEX Scales (FAQ) 5

An ATEX scale is a scale approved for use in potentially explosive atmospheres. It is designed so that it does not constitute an effective ignition source in defined Ex zones – depending on whether the atmosphere contains gas or dust.

The operator carries out the zoning as part of the risk assessment. It describes how frequently and for how long an explosive atmosphere may occur. Only then can the appropriate scale be selected.

Yes, depending on the model, ATEX scales are also available in calibrated or calibratable versions. Whether calibration is required depends on whether the scales are used in commercial transactions.

ATEX scales feature special design measures, tested components and appropriate marking for use in potentially explosive atmospheres. Standard industrial scales are not approved for this purpose.

No, even in Zone 2, only equipment that is suitable for this zone and marked accordingly may be used. The relevant equipment category and documentation are decisive.
