: Name：Dust Monitor for Detecting Filter Malfunctions; Type：FS700E01; Introduction：
The FlowSwitch 700E dust monitor is used to detect filter malfunctions caused by cracks or installation defects, for instance. The triboelectric measurement principle makes it possible to reliably detect dust penetration.

Main Benefits:
●  Maintenance free
●  Adjustable sensitivity
●  Adjustable switch
●  Condition indication with LED
●  Stainless steel housing
●  Compact form
●  Easy installation

Working Principle Technical Data Application Download

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.
