Lysimeter device for executing analysis in regions of e.g. ground, has lysimeter container whose lower side includes heat guide element, which stays in heat conducting contact with thermal conduction device

摘要

#CMT# #/CMT# The device has a lysimeter container (1) arranged in an edging (2) with a bottom (3) and a side wall (4). The lysimeter container and the side wall are thermotechnically decoupled from each other. A thermal conduction device (5) i.e. heat conducting container (9), is arranged at the bottom and stays in heat conducting contact with the bottom. A lower side (6) of the lysimeter container includes a heat guide element (7), which stays in heat conducting contact with the thermal conduction device. An evaporation protection unit i.e. oil film (8), is provided on a fluid surface. #CMT#USE : #/CMT# Lysimeter device for executing an analysis in regions of ground, water, plants or climate. #CMT#ADVANTAGE : #/CMT# The lower side of the lysimeter container includes the heat guide element, which stays in heat conducting contact with the thermal conduction device, thus minimizing temperature difference between a bottom material in the lysimeter container and a surrounding ground. The evaporation protection unit i.e. oil film, is provided on the fluid surface, thus minimizing decrease of liquid level by vaporization of the liquid and reducing a water evaporation rate. The device achieves better approximation to natural conditions for the bottom material in the lysimeter container, and allows the heat guide element to be unobstructedly moved in water in each direction. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perpendicular cross-sectional view of a lysimeter device. 1 : Lysimeter container 2 : Edging 3 : Bottom 4 : Side wall 5 : Thermal conduction device 6 : Lower side 7 : Heat guide element 8 : Oil film 9 : Heat conducting container #CMT#METALLURGY : #/CMT# The heat guide element is made of copper, stainless steel or aluminum.
