ElectroDynamic - Model Dust Alarm 40 -ElectroDynamic Bag Filters Failure Detectors

The Dust Alarm 40 provides incredible capabilities at a cost-effective price for the continuous monitoring of broken bags in Fabric Filter Baghouses. As a ‘Dust Gross Filter Failure Detector’, the instrument detects significant increases in particulate loading which indicates a failure in the arrestment plant, providing warnings of filter media degradation in baghouses and cartridge filters.
