Particulate matter transmitter

The PCTPM000 is a PM1.0, PM2.5 and PM10 Particulate Matter transmitter with RS485 Modbus-RTU output, suitable for outdoor air quality monitoring.

The dust particles concentration is measured using the laser scattering principle.

The transmitter is maintenance-free and has fast repsonse, high sensitivity and an excellent stability.

On request, an optional CO2 sesnor can be integrated in the transmitter.

The transmitter can be supplied with up to two optional configurable 4...20 mA, 0...5 V or 0...10 V analog outputs. The two analog outputs can be associated independently to any of the measured parameters.

The transmitter measuring circuit can be operated continuously or, in order to extend the life of the PM sensor, at cyclic intervals (default operating mode). The cyclic measuring range is user configurable.

The transmitter requires no maintenance and is  characterised by a quick response, high sensitivity, excellent stability and a long service life.
