APPLICATION
During the filling, it might occur that big bags are not properly attached, or that they tear. In this case a dust cloud arises and above a certain dust concentration it results in an explosive mixture. Electrical equipment and other ignition sources are in close proximity to this dust cloud, leading to a potentially dangerous situation for employees and the production facility. Therefore, the employees would shut down electrical equipment manually.
SOLUTION
With the AirSafe 2, the dust concentration in the ambient air of the silos is constantly measured. A trend value over 4…20 mA shows the dust content, an increase is detected right away. Reaching a threshold value, an alarm is triggered, resulting in an automatic shutdown of all potential ignition sources in the hazardous area around the silos, preventing a potential explosion.
CUSTOMER BENEFITS
- Continuous monitoring of the dust concentration in the silo area
- Protection of employees and the production facility from dust explosion by early shutdown of ignition sources
- Available in dust zone 22
