Filter Monitoring

Filter monitoring 1

Two inductive sensors (PLP) and a special electronic system were developed in order to be able to supervise filters. A difference signal is processed by the measuring electronics to allow supervision of the process cycle.

Monitoring with inductive sensors

Filter monitoring 2

Two inductive sensors and two electronic systems were developed in order to be able to supervise filters. The changing levels, seen in the following example, are measured before and after the filter. The sensor signal before the filter can be used to control a tilting furnace. The sensor signal after the filter activates the alarm for a filter change.
