ABSTRACT:
In a method and apparatus for determining the moisture content of a material with a measuring line extending through the material and having a proximal end connected to a signal generator for supplying a pulse signal to the measuring line, which pulse signal is reflected and returned back to the proximal end of the measuring line to which a comparator is connected for measuring the travel time of the signal supplied, and the reflected signal returned, to the proximal end of the measuring line and its amplitude is with compared with an amplitude corresponding to a threshold, an adjustable threshold value generator and controller are provided generating a threshold value signal which depends on the amplitude of the reflected signal.
