Ambient air dust monitoring

AirSafe 2

Continuous dust monitoring in ambient air: control system areas, silo areas, boiler houses, work stations

AirSafe 2 is an electrodynamic dust sensor monitoring leakages and dust concentration in ambient air in production facilities or workplaces. This versatile sensor allows you to keep under control your ambient environment. An alarm is generated when a threshold is exceeded

  • Controlled and self-monitored system
  • Calibratable alarm
  • Prevents creation of dust explosion zones
  • Dust concentrations in the ambient air are safely monitored
  • AirSafe can be used as early detection for dust which could endanger the workplace
  • Adapted for applications in zone 22 dust
  • Possible dust leakage from the process is quickly detected
  • Food
  • Paper
  • Chemistry
  • Power Plant
  • Cement
  • Hospital

Application examples:

  • Monitors dust concentrations on the basis of pre-set limit values
  • Can be used as early detection of particulate concentrations which could endanger the workplace
