Avoidance of ATEX zones through continuous dust measurement - Case Study

• Customer: Food manufacturer (Germany)
• Material: Sugar dust
• Installation: Clean gas side in front of the blower / Safety shutdown to protect the fan
• Function: Reliable measurement of the dust content

Application
A well-known food manufacturer in Germany measures the dust value in mg/m3 in its exhaust air upstream of the fan in order to switch it off before an ATEX zone is created.

The ignitable mixture of its dust is 30 g/m3. By calibrating to mg/m3, the desired switching point to turn off the system can be stored exactly. This way, the customer can be sure that the system is shut down before an ATEX atmosphere is created.
