CELL FOR THERMOSTATTING LIQUID Russian patent published in 2006 - IPC G05D23/30 

FIELD: technology for researching properties and composition of liquids.

SUBSTANCE: cell contains heat-conductive body of low thermal capacity, internal volume of which forms running thermostatted chamber with input and output apertures on the ends of its long sides, and heater of body made in form of thin-walled tube with two stoppers, mounted inside the tube at given distance from its ends. Body and heater are made so, that thermal flow from heater, applied to elementary volumes of thermostatted liquid, changes along long sides of chamber, increasing from its middle to input and output apertures. Heater may be made in form of two coils of copper enameled wire and two coils of manganic enameled wire. Coils of copper wire are positioned between stoppers, in the area of chamber, while coils of manganic wire are positioned between stoppers and ends of tube. In a variant of realization, tube material acts as heater.

EFFECT: increased thermostatting precision.
