Delta OHM PMsense - Particulate Matter Transmitter

PMsense 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 response, high sensitivity and an excellent stability.

The PM sensor can be operated in two ways:

• Continuous operating mode: the sensor is always active and measurements are continuously taken. In this mode at least 10,000 hours of PM sensor life are guaranteed.
• Discontinuous operating mode (default): the sensor is activated at regular intervals, when measurements has to be taken. This mode increases the PM sensor life.

On request, an optional CO₂ sensor can be integrated in the trasmitter.

The transmitter can be supplied with up to 2 optional configurable 4…20 mA, 0…5 V or 0…10 V analog outputs.
