AirSafe 2 consists of a flow duct and an integral electrodynamic dust sensor.
A current of air is drawn through the duct at approximately 100 m3/h.
Dust particles, carried in the air current, pass the sensor, this generates a charge transfer, which is used as the measurement signal.
This signal is converted by an analog outputs which could be used for display or control on PLC systm.
The AirSafe 2 flow duct is 500 mm long and 100 x 100 mm square.
The new design of the AirSafe 2 allows a fast and easy cleaning that makes it a perfect solution even in very dusty environment or suitable for sticky/caking material.
The integral dust sensor has a relay output, a active 4…20 mA analog output as well as ModBus RS 485 possibilities.
The unit is supplied pre-calibrated.
The alert point is set to approximately 25 mg/m³ of dust.
The user can set his own alarm threshold.
As an optional service, the alarm level can be calibrated at a particular dust level.
By using the visualisation software, up to 10 measuring points can be displayed and saved and can be interfaced to other computer programs, e. g. Excel.
