The relationship between water and soil thermal conductivity or resistivity is referred to as a thermal dry-out curve. The thermal conductivity of soil is directly related to the amount of moisture contained within the soil and depends strongly on the water content, composition within the soil, temperature, and bulk density. Dry-out curves are used when burying power lines to ensure that those power lines do not overheat as well as depending on the material tested, can determine common insulators of gas and oil reservoirs. With our TLS-100 we will dive into the field of dry-out curves and other Geo Engineering applications.
The transient line source (TLS) technique can be used for the thermal conductivity and resistivity of solid materials such as soil, concrete, natural stone, and low thermal conductivity ceramics. The TLS-100 is an ideal and standardized method for testing materials in-situ and in the lab. Thermtest’s TLS-100 is an easy-to-use and affordable instrument for all soils, rocks, concretes, and polymers.
