Galushkin In measuring the moisture content of materials with fluctuating chemical and granulo- metric compositions, it is more convenient to use the thermophysical characteristics than electrophysical properties. Thus, heat-based moisture meters are used to measure the mois- ture content of bulk materials differing widely in chemical composition [i, 2]. Presented below is a theoretical analysis of the thermophysical method of measuring moisture content, including a determination of the change in the capacitance of a small ferroelectric capacitor in a primary transducer over a fixed interval of time after its contact with a free-flowing material. We will examine the thermal processes taking place in an idealized model of such a transducer (Fig. l) [3, 4]. The principal component of the transducer is a metal plate of weight m and area S(d << /S). The bottom surface of the plate is in contact with a layer of the hulk material 3 of height h and temperature to. A heat- sensitive element i of weight ml << m is attached to the top surface of the plate. The en- tire system is enveloped by an adiabatic shell. The plate is heated
