Provides continuous measurement values for dust concentration as a trend signal or absolute values
The ProSens has been specially developed to carry out reliable dust measurement on clean sides after filters.
The measuring device provides measurement values for dust concentration, either as a trend signal or as absolute values (after calibration) for emission measurement.

MOUNTING & INSTALLATION
The ProSens can be installed in metal channels and pipelines.
The installation should take place away from any curves and other inserts such as flaps and valves.
The distance between the sensor rod and inserts in the channel should be at least 3 times the channel diameter in every flow direction.
Non-metallic channels must be sheathed using a metal sleeve, a metal foil or a close-mesh metal grid over a length of at least 5 times the channel diameter. After determining the installation location, a hole must be drilled in the channel wall to insert the welding casing flush. The casing is now welded into place vertically to the channel. The sensor rod is then inserted in this and fastened with a fixing screw. The length of the sensor rod should at least 1/3 and at most 2/3 of the channel diameter. It can be shortened to the respective optimal length (up to 70 mm) without a problem.
