Abstract
The device for measuring the moisture content of a sheet-like sample consists of a microwave oscillator, microwave transmitter and microwave receiver. At least three horn transmitters are flanged via an attenuator, directional couplers and attenuators to a frequency modulated microwave oscillator, opposite each of the horn transmitters, which are fixed on a frame, a microwave receiver with detector is arranged on the same frame, and a reference detector is flanged, via an attenuator, to at least one of the directional couples. The microwave receivers can be arranged so that they can be moved on the frame.
