METHOD OF DETERMINATION OF TEMPERATURE GRADIENT Russian patent published in 1995 - IPC

Abstract SU 1658712 A1

FIELD: thermal physics. SUBSTANCE: in process of measurement two thermally-dependent quartz resonators spaced by required base and placed in circuit of two quartz self-excited oscillators are put into needed physical region of medium. Dependence of frequency difference of quartz oscillators on time within measurement period is recorded. Value of temperature gradient is determined by calculation by results of measurements. EFFECT: increased precision and reduced time of measurements. 2 dwg
