TEMPERATURE CONTROL AND STABILIZATION DEVICE Russian patent published in 2003 - IPC

FIELD: thermal instrumentation engineering; research equipment for science and technology. SUBSTANCE: device that may be used where specimens are to be heated or cooled down to desired temperature and this temperature is to be maintained as long as necessary has heat insulating casing designed to receive piece of equipment whose heat is to be controlled, pieceof-equipment temperature measuring transducer, nonlinear correction unit, first-order differentiator, second-order differentiator, comparison element for piece of equipment whose temperature is to be controlled, unit for synchronizing with electronic computer, heat-insulating casing temperature comparison element, heat-insulating casing temperature measuring transducer, heat-insulating casing temperature error signal amplifier, error signal amplifier, rate-of-temperature- variation comparison element, temperature-variation acceleration comparison element, and second adder. EFFECT: minimized temperature stabilization time; enhanced accuracy. 1 cl, 1 dwg _
