Siemens launches dust sensors to detect smallest harmful particles in buildings

HQSIPR202007085927 Air duct fine dust sensorSiemens Smart Infrastructure has launched the PM2.5 duct type fine dust sensor

The sensor comes in two variants and creates a healthy as well as productive indoor air climate.

Part of the Symaro product group, the sensors measure dust and dirt particles, including fine sand, transmitting them rapidly and precisely to advanced building management systems for comprehensive climate monitoring and control.

This improves the indoor air quality of residential and commercial buildings, which in turn has a positive effect on the health and comfort of room occupants. By ensuring the early detection of hazardous particles, the sensors help achieve energy and cost-efficient control of the entire HVAC system.

Improved safety for buildings and users

The new PM 2.5 air duct fine dust sensors precisely measure and monitor the indoor and outside air quality, thus protecting the safety of building occupants. Together with a building management system, the sensors control the air quality in air handling units and can follow the air pollution in one or multiple rooms.

The new sensor is available in two variants. One sensor has duct probes that detect fine dust PM2.5, which are harmful to humans, and PM10. The other option has multiple measurement capabilities to measure fine dust, humidity and temperature. The duct type fine dust sensor design makes maintenance fast and easy.

Unique design for maximum precision

PM 2.5 duct type fine dust sensors offer high sensitivity as well as easy installation and configuration, especially in air handling units. The module has a service life of more than six years and is easy to replace. The probes rapidly provide correct measurements irrespective of room and building occupancy, thus reducing commissioning, service and operating costs.

With their unique mechanical design, which allows air to enter and exit through the same opening, the sensors offer a very level high precision. This unique feature provides an exact measurement in the inlet or outlet air ducts of the air handling unit. After the assembly of the head and detection chamber, the chamber is completely sealed off from the sensor head, making it impossible for air from the head to enter the chamber.

This ensures that only air drawn in from the air duct is measured. The new PM2.5 air duct fine dust sensors expand the Symaro sensor portfolio for CO2, humidity, volatile organic compounds (VOC), temperature, fine dust and much more applications.

Smart infrastructure from Siemens intelligently connects energy systems, building technology and industries to evolve the way we live and work.
