Use of a new thermal conductivity sensor for laboratory suction measurement
D G Fredlund, Fangsheng Shuai, Mingming Feng · 2020
The thermal conductivity matric suction sensor has been proven to hold great promise for the in situ and laboratory measurement of soil suction. Some difficulties have been associated with the use of early versions of the thermal conductivity sensors. An improved thermal conductivity sensor has been developed at the University of Saskatchewan, Saskatoon, Canada to overcome these difficulties. The new sensor has some design aspects that are superior to that of previous sensors. These design aspects make the new sensor a more suitable device for both laboratory and in situ soil suction measurements.
