Calibration of thermal conductivity sensors for measuring soil suction


, : Calibration of thermal conductivity sensors for measuring soil suction. ASTM Geotechnical Testing Journal 12(3): 188-194

The accuracy of suction measurements using thermal conductivity sensors is dependent upon their calibration. The experimental setup along with the calibration procedure are described. In general, results showed reasonable agreement between the calibration curve determined in this study compared to those provided by the manufacturer for matric suction ranging from 0 to 175 kPa.--modified journal abstract.
