AirSafe 2 - Continuous dust monitoring in ambient air with fan control

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.

Use

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.

Function

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.

System

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.

Mounting and Installation

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.
