FS-700E Dust Monitor Analogue or Switched

Application Scope of Use
The dust monitor FlowSwitch 700E is used for the detection of filter failure functions e.g. crack or defect in assembling. By the triboelectric measuring principle a dust breakthrough can be recognized reliable. FlowSwitch 700E can be put in metallic pipes and channels which shall be monitored on dust.

The technology is based on a modified triboelectric principle detecting particles interacting with the sensing rod and such particles just passing the rod. Build up on the rod surface will not be detected, only moving particles generate a flow rate proportional signal which is monitored by the electronic. Installation is done on the clean gas side downstream the filter at a metal duct by welding on of a thread bush boring through the duct wall and screwing in dust watch. On and off distance should this 3-fold of the pipe diameter area, the sensor length 1/3 to 2/3 of the pipe diameter.
The device isn’t usable at products, which build an electric conductive coating between sensing rod and pipe wall, caused of abrasion.
