This article proposes and examines an experimental method for determining the composition of materials in a sample using a new intelligent ballistic dual-channel transformer gravimeter (IBDTG) in a diagnostic setup (the GS gravimetric system). It is demonstrated that the IBDTG accuracy, speed, and reliability are superior to those of currently available gravimeters. Its design and operating principle are described. Currently, there are no theoretical or practical studies devoted to the feasibility and practicality of using an intelligent ballistic dual-channel transformer gravimeter to analyse metal composition in a sample or on a surveyed area of the Earth’s surface. A new intelligent ballistic two-channel transformer gravimeter contains a fixed tube, a magnetized test body in the form of a ball, a device for holding the test body in the initial position, a computer and an inductance winding, which is distinguished by the fact that the fixed tube is made of a dielectric material, the inductance winding acts as a primary excitation winding connected to a power source, which additionally contains two identical sections of a secondary output winding, connected in series-opposite to create two measurement channels, and the device for holding the test body in the initial position contains an electromagnet, which consists of an anchor made of a soft magnetic material and an additional winding, which is connected through a switch to an additional power source. This improves accuracy and reliability, reduces temperature dependence and sensitivity to cross-accelerations, and enhances linearity. The influence of vertical acceleration, instrumental errors, and errors due to non-identical parameters of the two channels are eliminated. The output signal power of the new IBDTG is increased by feeding the output signals of the two IBDTG channels to a computer, which generates an output signal from the gravimeter equal to twice the acceleration of gravity. The computer output signal is fed to a pre-trained Fuzzy module, which determines the metal composition of the sample or the area of the Earth’s surface being studied.

Key words: Fuzzy module, intelligent ballistic two-channel transformer gravimeter, automated diagnostic gravimetric system, disturbance effect, vibration acceleration, acceleration of gravity.
