Abstract: In a probe and an arrangement including a probe for determining a moisture content or a conductivity of a material, wherein the probe has a base body with two electrical conductors of which at least one has the form of a tape which is embedded in an electrically insulating material area of the base body in such a way that only an edge area of the tape-like conductor is disposed at the surface of the insulating material area of the base body for contact with the material.

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.

Abstract: In an apparatus for determining the moisture content of a medium forming a dielectric of a measuring conduit of a probe, which apparatus includes an electronic evaluation unit, a signal generator providing a pulse signal to one end of the measuring conduit, a receiver for receiving a reflected signal returned to the one end of the measuring conduit and a time measuring device for determining the time elapsed between the supply of the signal and the return of the reflected signal, the electronic evaluation unit is arranged in close proximity to the one end of the measuring conduit and provided with temperature compensating means.
