FIELD: measurement technology. SUBSTANCE: invention can be employed to determine temperature coefficient of frequency of samples from ferromagnetic material. Proposed device has base that carries two cases made of dielectric material placed in sequence. Excitation coils are positioned in cases along one axis. Tested sample passes through excitation coils. One of coils is connected to audio frequency generator and frequency meter. The other coil is connected to oscillograph. Permanent magnets are mounted by outer faces of cases. EFFECT: provision for measurement of temperature coefficient of frequency in samples of ferromagnetic material with specified measurement accuracy. 1 dwg
