DYNAairguard – Dust Sensor for Monitoring the Ambient Air

Application Area

The DYNAairguard dust sensor is a measuring device for monitoring the dust concentration in the ambient air.
The dust monitor is used, for example, in industrial production halls and detects when leaks occur in plants, machines or pneumatic conveying pipelines and dust escapes.
The use of the DYNAairguard effectively protects the health of employees.
In the case of explosive dusts, the danger of dust explosions is detected in time and intervention is possible.

 Continuous Dust Measurement for:

• Workplaces in production halls
• Machines and plants
• Pneumatic conveyor lines
• Big bag filling stations
• Silo enclosures

When delivered, the dust sensor is already preset and can usually be used immediately.

 How it works

The DYNAairguard technology is based on the proven electrostatic measuring principle (further development of the triboelectric principle), whereby particles are detected that collide with or fly past the sensor rod. Deposits on the sensor rod do not influence the measurement. Only moving particles generate a signal that is proportional to the dust content of the ambient air and is evaluated by the electronics.
To measure the dust concentration of the ambient air, an air flow is continuously drawn through the device by a quiet and at the same time robust fan. The air passes the sensor rod inside the rectangular duct and exits on the fan side.

Two electronic versions are available:
• with analogue output (4 … 20 mA)
• with relay output
