Engler information about float switch with ATEX approval
Our devices of the UniEx series may only be operated in connection with an Ex barrier / switch amplifier. For the operation of the UniEx.ANM series you need an individually programmed Ex barrier. For this purpose, ENGLER offers you specially configured Ex barriers.
A switch amplifier or pulse isolator for the ATEX area is a specialized electronic component used in potentially explosive environments to amplify, isolate, or transmit analog or digital signals. These devices are designed to minimize the risk of explosions in environments where flammable gases, vapors, mists, or dust are present. In the ATEX area, strict safety requirements apply to electrical devices and systems to ensure they do not pose ignition sources. A switch amplifier or pulse isolator approved for the ATEX area meets these requirements and provides additional protective mechanisms to reduce the risk of explosions. These devices typically feature galvanic isolation between input and output to ensure safe signal transmission. This means that the input signal is electrically isolated and has no direct connection to the output, preventing the transmission of hazardous voltages or currents into potentially explosive areas. Switch amplifiers or pulse isolators for the ATEX area can fulfill various functions depending on the application's requirements. For example, they can amplify, isolate, or convert analog or digital signals. They can also serve as interfaces between different devices or systems by facilitating signal communication between them.
What does ATEX mean?
ATEX is an abbreviation for "Atmosphères Explosibles," which translates to "explosive atmospheres" in German. It refers to a directive of the European Union, specifically Directive 2014/34/EU, which sets out the requirements for equipment and protective systems used in potentially explosive atmospheres.
What is the ATEX Directive?
The ATEX Directive encompasses a set of regulations and standards that apply across Europe. It covers aspects such as conformity assessment, product marking, requirements for technical documentation, and more. As such, the ATEX Directive is a crucial component of occupational safety and security in many industries. It helps minimize the risk of explosions and associated damage, creating a safe working environment.
Why is there an ATEX Directive?
The aim of the ATEX Directive is to ensure the safety of individuals, property, and the environment in potentially explosive atmospheres. An explosive atmosphere arises when flammable substances like gases, vapors, mists, or dust are mixed with air and can cause an explosion under certain conditions.
Which areas does the ATEX Directive cover?
The ATEX Directive applies to all areas where there is a potential risk of explosion, including the chemical industry, oil and gas industry, pharmaceutical industry, food industry, mining industry, and many others.
The ATEX Directive stipulates that equipment and protective systems used in potentially explosive atmospheres must meet certain requirements to function safely and reliably. These requirements include:
Compliance with the ATEX Directive is of utmost importance to ensure safety in potentially explosive environments. Non-compliant devices can pose significant risks to human safety and the environment.
What to be aware of?
Taking the necessary safety measures to minimize potential explosion risks is of paramount importance. Here are some key points to be aware of:
Classification of hazardous areas: The directive defines various zones based on the likelihood of an explosive atmosphere. There are Zones 0, 1, 2 for gas atmospheres and Zones 20, 21, 22 for dust atmospheres.
Conformity assessment: Manufacturers of equipment and protective systems must undergo a conformity assessment to ensure their products meet the requirements of the ATEX Directive. This involves testing and certification of products by an authorized body.
Marking: ATEX-certified devices and protective systems must bear a specific marking that provides information about the zone classification and other relevant details.
Documentation: Manufacturers must create technical documentation containing all relevant information about the product, its characteristics, conformity assessment, and other essential details.
Examples of ATEX products
There are various types of ATEX-certified products used in potentially explosive atmospheres, such as ATEX switches, ATEX sensors, ATEX lighting systems, ATEX pumps, and many others. These products are specifically designed for safe operation in explosive environments and contribute to avoiding potentially hazardous situations.
It's crucial for companies operating in potentially explosive environments to understand the requirements of the ATEX Directive and take appropriate measures to ensure safety. This includes selecting ATEX-certified products, conducting regular maintenance and inspection of equipment, and providing training to employees regarding specific risks and precautions.
