2. Function
The M-Sens 2 sensor functionality is based on precise high-frequency measurement and direct
digitalization of measured values, wherefrom results a high resolution. As the materials sur-
face and capillary moisture influences strongly its specific conductive capacity, the moisture
can be measured exactly by a constant averaged bulk density.
The calibration can be done very simply by the operator by pressing the button and entering
the referenced moisture contents.
In this context it is convenient that measured value fluctuations by bulk density variations are
balanced by an internal filter function. Additionally, measured value fluctuations by tempera-
ture variations are compensated automatically by the sensor.
