A sensor for the measurement of moisture in a flow of material, especially loose material such as meal material, grains, granulates and similar materials which are to be pressed to form feed pills in presses. The sensor comprises a tube piece of an electrically conductive material with circular cross-section, and an elongated pole which is of circular cross-section and is disposed with its longitudinal axis concentrically and electrically insulated in the tube piece, and which consists of an electrically conductive material. When the moist material flows between the inside surface of the tube piece and the outer side of the pole, the sensor works with the moist material's conductivity as a condenser for the capacitive detection of the moistness, which can be determined on the basis of the detection.
