2. Function
The M-Sens 2 sensor functionality is based on precise high-frequency measurement and direct digitalization
of measured values, where from results a high resolution. As the material surface 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 temperature variations are
compensated automatically by the sensor.
