Autonome Netzwerke von sensorgestützten Mini-Stationen
Das Cairnet®-Gerät ist eine autonome und netzwerkfähige Echtzeit-Luftüberwachungsstation mit bis zu 6 Cairsens®-Mikrosensoren und zellularer Kommunikation in einem wasserdichten Gehäuse.
Dank des integrierten Verteilers, der eine dynamische Probenahme ermöglicht, sind die Messungen genau und zuverlässig. Die elektronischen Verbindungen sind abgedichtet und vor Feuchtigkeit und korrosiver Umgebungsluft geschützt.
Cairnet® ist kompakt, leicht einsetzbar und dank seiner Solarzellen und Batterie autonom. Es ermöglicht Ihnen eine kostengünstige Überwachung von Staub und Gasen und gibt Ihnen ein vollständiges Bild der Umweltauswirkungen Ihres Betriebs.
Es bietet eine beispiellose Flexibilität bei der Erstellung genauer und dynamischer Luftqualitätsmessungen in einem breiten Spektrum von Branchen und Anwendungen.
Echtzeit-kontinuierliche Messung und Überwachung von bis zu 6 gas- und partikelförmigen Schadstoffen gleichzeitig, darunter: H2S/CH4S, NH3, nmVOC, O3+NO2,NO2, CO, SO2, PM10, PM2.5 & PM1
- Measurement of environmental parameters: temperature, relative humidity and pressure
- Plug & Play Network: automatic pairing (Cairsens® / Cairnet® / Caircloud®)
- Dynamic sampling and improved protection against moist and/or corrosive environments
- Optional: Ultrasonic anemometer to measure wind direction and speed. Autonomous
thanks to its integrated solar panel and battery
- Automated data saving (micro SD card) and push : no consequence in case of lost
communication service - Communication frequency and measured data volume adapted automatically to the
autonomy of the station - Very high sensitivity to capture low level gas and particulate concentrations
- Modular, easy to use and move on-site: no cables
- Cairnet® requires only annual maintenance: when sensors should be renewed
- Operating cost savings: process adjustment & Improvement of local communication
(neighbors & authorities) - Possibility to set up hybrid AQMS networks (reference stations & mini-stations)
- Odor monitoring: WWTP, recycling, pulp and paper manufacturing, sewerage treatment facilities, refineries
- Indoor and outdoor air quality monitoring: smart cities, road-side & tunnels, schools, airports, ship terminals…
- Process leak detection and monitoring of fugitive emissions: quarries, storage facilities, mines, manufacturing plants
- Forecasting of industrial fence line emissions
- Environmental impact assessments
- Health and safety: mines, industrial sites, construction
- Mapping and modelling pollution sources
- Every Cairnet measurement point consists of:
- Solar panel and its battery
- Wireless communication module
- Weather protection enclosure including up to 6 Cairsens miniature sensors, each measuring one or two pollutants. The sensors are to be selected from the list, function of your specific requirements.
- Optional: ultrasonic anemometer. If this option is selected, it replaces a Cairsens® sensor
