The broken bag detector DYNAguard GM is used for the detection of filter malfunction e.g. a broken bag or an installation error.
The DYNAguard 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 electronics. Three electronics versions are available with analogue (GM20), relay (GM01) or transistor (GM02) output. Adaptation is done under normal conditions by switches and potentiometer, DYNAguard's alarm level (GM01, GM02) can be set above this background. Signal damping is selectable by the user.
The length of the sensor rod should be 1/3 to 2/3 of the duct diameter, 800mm maximum.
The broken bag detector is installed 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 DYNAguard. Upstream and downstream the sensor at least three duct diameters should be straight without any fittings like valves or dampers.
Comissioning is simple and requires no tools or speciali equipment.
Proven technology for reliable dust measurement.
