Abstract
In this paper the methodical and instrumental aspects of the correction of temperature influences in moisture of bulk material express measurement are considerate. Bilinear coefficients of capacitance dependence on moisture and temperature were determined to provide a correction based on the performed measurements of sensor capacitance for 4 reference moisture specimens of the test material with simultaneous measurement of their temperature. Based on obtained relationship, the temperature influence correction function was determined. The combined standard uncertainty of the correction was estimated as a function of the uncertainty of the 8 influencing factors. It was shown that the correction reduces the systematic influence of temperature by 10 to 40 times.
