FIELD: measuring engineering.
SUBSTANCE: device comprises receiver-converter, thickener, and measuring electric circuit. The converter has three electrodes, common and two outer ones, and is made of a rectangular vessel made of a dielectric material separated into three sections. The first section and second section are used for charging the product to be tested, and third vessel is filled with a material whose dielectric permeability close to that of the dry materials to be tested. Tree electrodes of the receiver-converter are connected to the bridge circuit. The electric circuit of the device has generator, bridge circuit, two peak detectors, differential amplifier with linear and nonlinear amplification, unit for processing the signal, and recorder. The electric circuit is provided with the unit for temperature compensation.
EFFECT: enhanced reliability.
