- The DUST ALARM 40 is reliable, cost-effective instrument for the continuous monitoring of broken bags in Fabric Filter Baghouses. The instrument combines the benefits of ElectroDynamic™ Probe Electrification technology and separate control unit with a scaled 4-20mA output, dual local alarms and dual alarm relays, and a clear, simple icon-driven menu and display to deliver pragmatic and dependable broken bag monitoring. The DUST ALARM 40 electronics exclude short term signal increases associated with pulse cleaning of the bagfilter by appropriate setting of the alarm delay period. As a ‘Dust Gross Filter Failure Detector’, the instrument detects significant increases in particulate loading which indicates a failure in the arrestment plant.
- 4-20mA output (optional) scaled to 0-100% of primary alarm level (which is user defined), for external indication of dust level relative to alarm set point
- High quality leak response with sufficient dynamic range and time response to track emissions from single and multi-compartment pulse cleaned bagfilters
- Dual alarms for filter failure and early warning, user-defined to instantaneous or average levels above normal, with alarm delay
- Separate control unit for remote installation with a full-colour LCD display with icon-driven menu and effective graphical user-interface for instrument configuration and dust / alarm level status
