1 INTRODUCTION
PMsense
is a
PM1.0
,
PM2.5
and
PM10
Particulate Matter transmitter suitable for
outdoor air quality monitoring.
The dust particles concentration is measured using the laser scattering principle.
An optional CO
2
sensor can be integrated in the transmitter (
PMBsense
).
The transmitter has a digital RS485 output with MODBUS-RTU or ASCII proprietary
protocol. A version with two additional 0/4…20 mA (0…10 V
on request when order-
ing ) analog outputs is available. The two analog outputs can be independently associ-
ated with any of the measured parameters.
The measuring circuit of the transmitter can be operated in continuous mode or, in
order to extend the PM sensor lifetime, at cyclic intervals (default operating mode).
The measuring cycle interval is user configurable.
The transmitter is maintenance-free and has fast response, high sensitivity, excellent
stability and long operating life.
