Understanding Explosion-Proof Zones and Equipment Categories Correctly - What is an ATEX Zone? A Clear Explanation Using Real Examples
There is always a risk of explosion in areas where flammable gases, vapors, mists, or dust may be present. Examples include the chemical industry, energy supply, biogas plants, solvent processing facilities, hydrogen infrastructure, and gas distribution systems. An important point to understand about explosion protection is the location of the measurement point within the zones. A common misconception is that if flammable gas is used, the highest hazard classification automatically applies; however, the frequency of explosive atmospheres can vary significantly from one industrial plant to another. For instance, explosive mixtures may always be present inside a tank, while they rarely occur in well-ventilated piping areas, typically only during abnormal situations. This is precisely why ATEX systems classify zones as 0, 1, and 2. The related links below provide detailed explanations of the basic principles of ATEX zones, real-life examples from hydrogen filling stations, comparisons of protection concepts (why safety barriers or isolation amplifiers are necessary), and what types of pressure sensors we at KELLER can offer for each zone.

Examples of applications for explosion-proof pressure sensors - automotive, petroleum, aerospace, chemical industries, etc.
Products suitable for environments with a risk of explosion are used in a wide range of applications. Since 1988, KELLER has been developing and manufacturing explosion-proof pressure measurement technology. Based on years of experience and achievements, KELLER's explosion-proof pressure sensors have received high praise in many industries. Examples of applications (one example each): - Automotive sector: Painting robots When atomized by a spray nozzle, the mist can generate a flammable mixture. - Oil sector: Monitoring fuel levels at gas stations At gas stations, there is a risk of gas atmospheres exploding due to electrical sparks. - Aviation industry: De-icing machine liquids De-icing fluids contain more than 50% highly flammable glycols and are used in a mixture with water. - Chemical industry: Monitoring the storage conditions of chemicals Warehouses owned by chemical manufacturers and distributors store numerous containers of various chemicals, which may contain all kinds of explosive and hazardous substances.
