Technical data

Application Area

The DYNAairguard is a measuring device for monitoring the dust concentration in the ambient air.
The device 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 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
