A Dust particulate monitor is a device that is mounted in the discharge stack of a dust collector and continuously monitors the amount of particulate discharge. The particulate monitor uses a technology known as Triboelectric or Triboelectricity. When two different materials come in contact, it is likely that one will leave with more electrons than it started with and the other will leave with less, this is called Triboelectric Effect. The interaction between the probe and particles produces a charge transfer within the probe. The charge is then converted to an output signal.Dust Particulate Monitoring systems
