THERMOMETRICAL CHAIN (THERMIC CHAIN) Russian patent published in 2018 - IPC E21B47/06 G01K13/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the measurement of temperature by means of thermometric electrical sensors and is designed for simultaneous measurement and recording of soil temperature values at several points of the object, depending on its design, in particular in thermometric wells of any type in the field, conducting stationary and laboratory studies of the temperature mode of thawed, frozen, cooled and freezing/thawing soils, arrangement of the network for monitoring the thermal mode of soils with a large number of observation points, including those in fire, explosive and aggressive environments. Proposed device includes temperature sensors that are soldered directly to the wires of the flexible cable, pressed into the molten material based on the polyethylene composition of the same brand as the cable sheath, while forming the flexible, hermetic, monolithic construction, which is equipped with the connector, in the housing of which the electronic circuit board is installed, which contains the service information, including correction factors for each temperature sensor.

EFFECT: increased accuracy of measuring the temperature mode of wells of various types, increased reliability of the device when working in fire, explosive and aggressive environments, as well as increased life of the device and extended range of its use.
