METHOD OF CONTACT TEMPERATURE SENSOR SHELLS TEMPERATURE AND THERMAL INERTIA MEASURING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC G01K13/00 G01K15/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment and is intended for use in oceanography. Claimed is a method of contact temperature sensor shells temperature and thermal inertia measuring. For this, three sensors are used, consisting of sensitive elements with different thermal inertia parameters, placed into external shells with the same thermal factor values and internal heat-conducting medium with different thermal inertia parameters. Based on the of sensor sensing elements θ_t1, θ_t2 and θ_t3 current temperature determining the medium θ_tc current temperature, thermal inertia current parameter of the sensors ε_t3 outer shell, sensitive elements ε₁₁, ε₂₁ and ε₃₁, inner shells ε₁₂, ε₂₂ and ε₃₂ using solutions x_j of linear algebraic equations system of the form of , ,N≥18, where a_tj and C_t are coefficients, calculated from N values of the θ_t1, θ_t2 and θ_t3 current temperatures and derivatives thereof up to the third one.

EFFECT: technical result is an increase in the dynamic temperature measurements accuracy and metrological durability by determining the sensitive elements and sensor shells thermal inertia parameters in the operating mode.
