Admittance Monitoring of Nonelectric Nature Objects
Abstract
Problems of development the methods of monitoring the quality indices of non-electric nature objects are in the highlight of the paper. The chain of experimental investigations of capacitance primary transducers in terms of their time stability (durability) and manufacturing material efficiency has been undertaken. The nature of frequency dependence of admittance on the temperature and different solution concentrations has been researched. Due to the results of investigations the method of identifying the general salt concentration in soil is proposed.

Streszczenie
W pracy przedstawiono propozycję udoskonalenia metod monitorowania parametrów jakości obiektów o charakterze nieelektrycznym. Zbadano stabilność czasową i wpływ rodzaju materiału elektrod na parametry przetworników pojemnościowych oraz częstotliwościowe zależności składowych admitancji od temperatury i stężenia roztworów. Zaproponowany sposób określenia całkowitego stężenia soli w glebie.
Słowa kluczowe
