Device for measuring the thermophysical properties of modified soils

摘要

The inventive device for measuring the thermophysical properties of modified soils allows the study of the thermophysical properties of various substances in a controlled atmosphere. The device allows you to place several different types of nanocalorimetric sensors (XEN-40014, XEN T08, FlashDSC chip) inside the case. The device can be integrated into instruments for measuring the thermophysical and optical parameters of samples. The device expands the capabilities of nanocalorimetry methods by realizing the possibility of heating the sample to 400 ° C and cooling the sample to 25 ° C under conditions with a strictly specified relative humidity inside the measuring chamber. In addition, the design of the device allows the use of sensors having two active zones, one of which can be used as a reference cell. The device includes a housing configured to connect to the connector and equipped with windows of X-ray transparent material, in which the nanocalorimetric sensor is located. There are special cut-outs in the cover and base of the case for installing transparent windows, ensuring the placement of the active part of the sensor in the projection of these cut-outs. An electric board is integrated in the housing for the ability to connect various sensors. The technical result is the expansion of the capabilities of nanocalorimetry methods by providing the ability to accurately control atmospheric parameters around a nanocalorimetric sensor. 5 ill.
