CAPACITANCE MEASUREMENT OF THE MOISTURE CONTENT OF SAND ON A CONVEYOR BELT

KAPZITIVE MESSUNG DES FEUCHTIGKEITSGEHALTES VON SAND AUF DEM FOERDERBAND

The capacitative measurement method described here for the moisture content of sand is an improved electrical resistance measurement. With the aid of a calibration curve, the water content may be measured exactly to within 0,5% by weight. As the result is available immediately, the production of concrete can be considerably improved, taking into account the natural water content. In the case of asphalt mixing plants, the heating oil demand can be adjusted in relation to the water content of the aggregates. /TRRL/
