发明名称 Device for measuring thermal properties in a medium and method for determining the moisture content in the medium
摘要 <p>The invention relates to a method and device for determining the water content of a medium, particularly of soils and the like, in which a probe or sensor (8) located in the medium is heated. A temporary change in temperature is effected by dissipating the thermal energy through the moisture in the area surrounding the probe, this change in temperature being used for determining the moisture content of the medium. An intermediate layer (13) is placed between the probe and the surrounding medium and is absorbent and mechanically deformable for mechanically coupling the probe to the surrounding medium and for decoupling the probe and the surrounding medium thereby enabling a precise measurement of moisture content to ensue while being subjected to the least possible thermal influence by the largely undetermined surrounding medium.</p>
