TDR probe for measuring volume of water coming from atmospheric precipitates

摘要

the probe is characterized by the fact that the sensor is equipped with a water collector, which is a plate (1) made of a porous material having a porosity of 10 to 30%, preferably ceramic korundowej or cyrkonowej, which is placed on a flat laminate (2) foliowanym copper layer, where a layer of metal on the laminate (2) constitutes a first element (3) pairs of elements (3,3 ') of the waveguide parallel tdr sensor, while the second element (3) is placed on the other side of the plate (1) and is in the form of wire made of steel or copper kwasoodpornej nadrukowanej path and is connected to the path of impedance characteristic less than impedanc i characteristic concentric cable, connecting with the tdr probe, both elements (3,3 ') of the waveguide parallel adjacent closely to plate (1) and (2) printed laminate and copper path are secured antykorozyjnie. the probe may be compared with the tdr sensor unit, with the thickness (s) of plates (1) each of the following sensor is different from the previous. the probe may be compared with the tdr sensor unit using plates (1) with different porosity.
