DEVICE OF MEASUREMENT OF MATERIAL POROSITY PARAMETERS Russian patent published in 2015 - IPC G01N15/08 

FIELD: instrumentation.

SUBSTANCE: invention relates the measuring devices, and can be used during quality estimation of the porous materials, for example ceramics, metal-ceramics. The objective solved by the invention is increased measurement accuracy. The device contains the measuring chambers 1, pump 6, connected through the valves 7, 9 with the measuring chamber 1, PC 12 connected with the measuring channels 1 at one side, and with pump 6 at another side, work chamber 2 connected with atmosphere, measurement control system 11 connected with pump 6 at one side, and PC 12 at another side, pressure transmitters 10 installed on the measuring chambers 1, and temperature transmitter 13 installed on the work chamber 2. The temperature transmitter 13 is connected with PC 12. In the measuring chambers 1 several isolated cavities 3. In the work chamber 2 one cavity 4 is made. Time sensor is built in PC 12. Pressure transmitters 10 are connected with the measurement control system 11, and their number corresponds to number of the chamber cavities.

EFFECT: increased accuracy.
