M-Sens 2

Moisture in Solids

M-Sens 2 is the microwave sensor for continuous humidity measurement in dry bulk solids. The instrument is used for simple retrofitting for measurement in:-
•    container outlets
•    conveyor screws
•    On conveyor belts
•    Slides etc.
 

Features

The M-Sens 2-sensor works with precise high-frequency measurements and direct digitalization of the measurement values and thus a high resolution. 

Since the surface and capillary humidity of a material has a strong influence on its dielectric constant, the humidity can be determined exactly given a constant medium bulk density. By way of support, any fluctuations of the measuring value caused by the bulk density are balanced through an internal filter function. Temperature-related fluctuations of the measuring value are automatically compensated by the sensor.

The calibration of the system can easily be carried out by the operator. On the installed system, the calibration is a matter of pushing a button and entering the humidity reference value.
