Monitoring of dust concentration in control system areas, silo areas, boiler houses or work stations.
The new generation of AirSafe is a compact, reliable, accurate and versatile ambient air dust monitoring device.
- The creation of dust explosion zones can be prevented.
- Dust concentrations at work stations are safely monitored.
- Possible dust escape from system parts is quickly detected.
- AirSafe 2 can be used as early detection for dust which could endanger the workplace.
- Available for applications in zone 22 dust (EX 3D).
- With our fan control system, you are sure of the validity of the measurement.
Electrodynamic sensor technology from ENVEA-SWR has proven itself in thousands of applications for measuring dust concentrations in process systems.
AirSafe 2 is the new generation of measuring instrument which can monitor the dust concentration in ambient air, for example in control system areas, silo areas, boiler houses or work stations.
AirSafe 2 has the new feature of a fan control system which allows you to be informed of any fan failure to have a significant improvement in sensor reliability.
AirSafe 2 monitors concentrations on the basis of pre-set limit values.
For example, to avoid the accumulation of dust in explosion zones or to detect unnoticed accumulation of dust from processes.
AirSafe 2 can be used as early detection for dust which could endanger the workplace.
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.
AirSafe 2 can be installed anywhere in a room.
Except of high ambient temperatures, there is no need to maintain distances from units or walls.
AirSafe 2 can be wall-mounted using brackets provided.
