Outdoor air quality monitoring needs fast, dependable particle data that can be integrated into existing measurement networks. This particulate matter transmitter measures PM1.0, PM2.5 and PM10 concentrations using the laser scattering principle, making it suitable for smart cities, municipalities, road controls and environmental studies.
Flexible operation helps match measurement performance to the monitoring task. The measuring circuit can run continuously for uninterrupted data collection or in user-configurable cyclic intervals to extend PM sensor lifetime. In the default 5 minutes cyclic mode, the sensor lifetime is approximately 5 years; in continuous mode, it is more than 10,000 hours at 1 meas./s.
System integration is straightforward via RS485 with Modbus-RTU or ASCII proprietary protocol. Versions with two additional 0/4…20 mA or 0…10 V analog outputs allow independent assignment to measured parameters, while the polycarbonate housing with rain-proof and UV resistant inlet air filter supports outdoor use with IP 53 protection.
The transmitter measures dust particle concentration in air using laser scattering technology.
PM1.0, PM2.5 and PM10 are measured across the same 0…1000 µg/m3 range for each pollutant.
The measuring circuit operates continuously or at cyclic intervals. The cycle interval is user-configurable.
PM measurements are available as averages over 10 seconds, 60 seconds or 15 minutes, with defined update intervals.
Versions are available with two additional 0/4…20 mA or 0…10 V analog outputs, each independently assignable.
The transmitter uses an M12 8-pole circular connector and includes a bracket with U-bolt for mast mounting.
