The fixed particle sampler represents a technologically advanced solution for the continuous monitoring of suspended particles in the air. This device is designed to provide precise and reliable real-time measurements, detecting particles in the range of 0.3 to 10 μm. This capability enables a comprehensive and detailed assessment of atmospheric pollution, which is essential for managing air quality across various sectors.

 

The operating principle relies on an internal pump that draws the sampled air through a laser sensor. When particles pass through the beam of light, their presence causes light scattering. This phenomenon is detected and converted into an electrical pulse by a photoelectric transducer. The size of the generated pulse is directly proportional to the particle size, allowing precise identification of their diameter. The results are expressed in particles per 28.3 liters, particles per liter, or particles per cubic meter, offering various data presentation modes to meet specific analysis needs.

 

The sampler is equipped with cutting-edge communication interfaces like Modbus RTU and MQTT on RS-485, ensuring seamless integration into industrial control networks. These standardized communication protocols are widely used in the automation sector and enable efficient, secure, and real-time data management. Through these interfaces, the device can be monitored and configured remotely, simplifying data collection and analysis from centralized systems. The RJ45 port and the 4-20 mA analog output across four channels offer further integration possibilities with data acquisition systems and external control units, making the sampler a highly versatile tool adaptable to different infrastructures.

 

One of the main features of the sampler is its configurability, which allows customization of the sampling and pause times. The sampling time can be set between 1 and 10 minutes, while the pause time can range from 1 to 1,000 minutes. This functionality ensures flexible management of the monitoring cycle, adapting to both frequent measurement needs and less intensive monitoring requirements. This customization capability makes it suitable for a wide range of applications, including industrial pollution control and air quality monitoring in sensitive environments.

 

The device is designed for permanent installation and comes in a robust wall-mounted housing, capable of withstanding harsh environmental conditions. Its solid construction ensures long operational life, even in hostile industrial settings, minimizing the need for maintenance. This makes it ideal for outdoor applications, production plants, and other areas where continuous and reliable air quality measurement is required.

 

The particle sampler finds application in various sectors, including industrial production, cleanroom management, healthcare, and hospital facilities, where maintaining high air purity standards is essential. It is also widely used in urban areas to monitor outdoor air quality, especially in high-traffic zones or near industrial facilities. In healthcare settings, for example, this device allows continuous monitoring of particle levels to ensure the safety of patients and medical staff, reducing the risk of contamination.

 

The use of this device goes beyond monitoring, as it also helps optimize the efficiency of ventilation and filtration systems, ensuring that contamination levels are kept within regulatory limits. Due to its precision and reliability, the sampler is an indispensable solution for ensuring that facilities and production processes comply with regulatory requirements and safety standards. The data collected is critical for evaluating the performance of air quality control systems and implementing improvements if necessary.

 

In summary, the fixed particle sampler represents a combination of high technology, precision, and flexibility. With its advanced measurement capabilities, standardized communication interfaces, and robust construction, it is the ideal tool for continuous environmental monitoring in industrial, healthcare, and any context where air quality is a critical factor.
