Surface probe for moisture content measurement in building materials by time domain reflectometry comprising a transmission line made of two elastic conductors attached to an elastic dielectric made of foam to enable adaption to curved surfaces

摘要

Probe for moisture content measurement especially in elements with curved surfaces is characterized in that it has elastic transmission line elements (2) which allow the probe to adjust to shape of the measured material or building object. Elements (2) are made from elastic metal and in section have the shape of flat bar allowing their deformation. The probe also has elastic dielectric (1) from isolating foam material, which allows for adjusting the elements (2) to conform with irregular shape of the measured surface.
