Rilevatore elettrodinamico di rottura maniche


Rilevatore di rotture filtro macroscopiche con unità di controllo. Rileva aumenti significativi del carico di polvere segnalando il degrado del mezzo filtrante in filtri a maniche o a cartuccia.

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.
  • The Dust Alarm 40 (DA-40) is an extremely rugged, accurate & repeatable dust measurement device
  • Full colour, icon-driven menu and display
  • Two independent alarm set points
  • Relative dust reading on clear scale 0-100%
  • Dust “Overrange” icon
  • Security setting
  • Digital Signal Processing
