METHOD AND DEVICE FOR PROXIMATE ANALYSIS OF MOISTURE CONTENT AND HEAT CONDUCTIVITY OF NONMETALLIC MATERIALS Russian patent published in 2011 - IPC G01N27/22 G01N25/18 

FIELD: physics.

SUBSTANCE: capacity of transducer kept in air is measured to convert measured capacity into pulse burst entered into device memory. Transducer is brought in contact with analysed material and measurements, conversion and memorising are reiterated to compute moisture content by formula w=a+b₁·(N₁- N₃)+b₂·(N₁-N₂)², where w is moisture content; b₁, b₂ are empirical constants stored in device memory; N₁ and N₂ are number of memorised pulses with transducer in air and in contact with material, respectively. Heat conductivity is calculated by formula λ=λ_0i+k_i·w, where λ is sought heat conductivity, λ_0i (heat conductivity of dry material) and k₁ (heat conductivity increment factor per moisture content percent) are constants for particular materials stored in device memory. Obtained values are displayed on device indicator in turn in their relevant units of measurement. Invention covers also device for described method.

EFFECT: expanded operating performances.
