The transmitter has a 4 ... 20 mA output proportional to the trend of the dust burden.
If there is an error found by internal system checks the output is set to 2 mA.

The best location for installation of the ProSens is in a duct section where there is even laminar flow
distribution.
The optimal position would be in a horizontal or vertical section of the duct. There should not be bends,
valves, dampers or other obstructions, either upstream or downstream, for a distance of at least 5 times the
pipe/duct parameters. (See figure 2)
