Why choose airflow guards in ATEX areas?
Flow guards for air ATEX are essential for monitoring in explosive areas. They do valuable work in the control and measurement of air currents in environments in which there is a high risk of explosions. There are industries such as chemistry, mining, oil and gas or in systems that work with flammable gases, steam or dust. In these environments, it is of crucial importance to monitor the air currents with a flow guard ATEX carefully in order to avoid potentially dangerous situations, to intervene in good time and to ensure security.
The peculiarity of the Flow guard ATEX is that this is developed and certified according to the strict safety regulations. Flow guards ex protected must be constructed in such a way that they cannot generate sparks or reach temperatures that could trigger an explosion. They have to be robust and reliable in order to work precisely under rough conditions.
A flow guard ATEX should therefore always be certified for use in ex-areas, as with us and correspond to the applicable standards and regulations. In order to ensure constant performance and security, a regular check of the devices is also indispensable.
When choosing and configuring your flow guards ATEX, we make sure that these are suitable for the specific properties of the respective ex-range. This applies above all to the type of combustible gases and the ambient conditions. The air flow guard ATEX becomes an important part of your integrative security strategy.
How do air flow monitoring work in the ex-area?
Depending on the type of sensor used, flow guards work according to a different principle. In the case of calorimetric speed or flow measurement, the flow of gas or liquid is measured depending on the heat transfer within the medium to be measured. The basic principle of a calorimetric flow guard ATEX is relatively simple: a heating element and at least one temperature sensor are positioned directly in the air flow. The heating element continuously releases heat to the surrounding medium. The amount of the heat and the resulting temperature change in the medium are recorded by the sensor.
Since the heat transfer depends on the speed of the current - quickly flowing gases take off more heat than slowly flowing - the sensor can transfer the temperature difference to the flow speed and indicate the flow of the medium.
Calorimetric flow meter are known for their accuracy and reliability and are therefore often used where precise flow measurements are required. They are also able to function in a variety of environments, including those with corrosive or contaminated currents, and require relatively little maintenance compared to other flow meters. Their versatility makes them a popular choice in areas such as chemical processing, in HLK systems, in the automotive industry and in water and sewage treatment.
What are the advantages of flow guards ATEX in explosion protection?
ATEX areas require special safety precautions, since small sparks or too high temperatures can trigger an explosion. One of the main advantages of flow monitoring in ATEX areas is increased security. Due to the continuous monitoring of all gas or air currents with a flow guard ATEX, potentially dangerous conditions such as gas leaks or unusual flow patterns can be recognized at an early stage. This enables you to intervene quickly and prevents serious accidents.
In addition, an efficient monitoring of the air flows by means of flow guard ATEX enables optimized process control. In many industrial productions, the precise control of gas or air flows is crucial for product quality and efficiency. With precise measurements, work processes can be better controlled and optimized. This in turn contributes to increasing efficiency and cost savings.
Ultimately, with a flow guard ATEX, you can fulfill the legal security standards to your company.
In summary, flow monitoring systems for ATEX areas offer the following advantages:
- Increased security: early detection of dangerous conditions such as gas leaks
- Optimized process control: precise control of air and gas flows to improve product quality and efficiency
- Compliance with safety regulations: fulfillment of legal requirements and avoidance of punishments
- Cost savings: increase in efficiency through optimized processes and avoidance of accidents and downtime
- Risk minimization: reduction of the risk of explosions and other security -relevant events
How do flow guards differ zone 1 and flow guards zone 2?
Although the flow guards of Seikom Electronic can be used in both zone 1 and inin zone 2, the main differences of these zones are in the frequency and duration of the occurrence of explosive atmospheres.
Zone 1
Zone 1 includes areas in which an explosive atmosphere occurs from a mixture of air and combustible gases, steam or fog under normal operating conditions. Flow guards that are used in this zone are designed in such a way that they function safely even under these more frequently occurring and potentially longer explosive conditions.
Zone 2
Zone 2 refers to areas in which an explosive atmosphere rarely and briefly occurs. Although the likelihood of an explosive event in Zone 2 is lower, it still requires the use of devices that are secured against such rare but potentially dangerous situations.
The flow guards of Seikom Electronic, which can be used in both zones, have no technical differences due to their zone affiliation. The main difference between the zones lies in the environment characteristics and the likelihood of the occurrence of an explosive atmosphere. The selection of the suitable flow guard ATEX is therefore not based on technical differences between the devices, but on a precise evaluation of the specific conditions and risks of the location.
Where are the areas of application of flowers ATEX?
Certified flow guards ATEX are used in different areas that all have in common that the atmosphere is a potential risk of explosion.
These include:
Chemical industry
In systems where inflammatory chemicals, solvents and gases are used, precise monitoring of the air flow is necessary to prevent explosive mixtures.
Oil and gas industry
In refineries, drilling platforms and pipelines, where combustible liquids and gases are processed, flow guards ATEX are crucial for security.
Pharmaceutical industry
In the manufacture and processing of pharmaceuticals, where work is often carried out with fleeting fabrics, these flow guards ATEX contribute to compliance with safe working conditions.
Power plants
Especially in areas where coal is processed, monitoring the air flow is important to minimize the risk of dust explosions.
Mining
Underground mines, in particular those that release flammable gases such as methane, require constant monitoring of the air flow to ensure the safety of the workers.
Color and paint industry
The production and processing of colors and varnishes often involves slightly inflammatory solvents, which requires precise monitoring of the air flow by means of a flow guard ATEX.
