Abstract
Способ определения разности динамических погрешностей датчиков температуры поверхностного типа, заключающийся в измерении текущих значений температуры, получении ее эталонных значений и определении искомой величины как разности измеренных и соответствующих им эталонных значений температуры, отличающийся тем, что, с целью расширения области применения способа путем обеспечения возможности определения погрешностей в системах с холодильником и теплоносителем, предварительно на рабочем режиме разогрева холодильника измеряют изменение во времени расхода и температуры теплоносителя на входе холодильника, за эталонные значения принимают значения температуры на выходе холодильника, полученные в результате моделирования процесса его разогрева, а затем при достижении пропорциональности изменения модуля разности измеренных и эталонных значений упомянутой температуры скорости ее изменения на всем протяжении разогрева определяют искомую величину по указанной разности на участке процесса разогрева холодильника от момента окончания переходных процессов, обусловленных инерционностью теплопередачи от теплоносителя к теплоотдающей поверхности до момента достижения максимальной скорости увеличения температуры на выходе холодильника.The method of determining the difference of dynamic errors of surface-type temperature sensors, which consists in measuring the current temperature values, obtaining its reference values and determining the desired value as the difference between the measured and corresponding reference temperature values, characterized in that, in order to expand the scope of application of the method by ensuring that errors in systems with a refrigerator and coolant, previously on the operating mode, the heating of the refrigerator is measured by change over time, the flow rate and temperature of the coolant at the inlet of the refrigerator, the reference values are taken as the temperature values at the outlet of the refrigerator, obtained by simulating the heating process, and then when the modulus of change of the difference between the measured and reference values of the said temperature reaches the proportionality of the warming up determine the desired value of the specified difference in the area of the process of heating the refrigerator from the moment of completion of the transient processes, due to inertia of heat transfer from the coolant to the heat-transfer surface until the maximum rate of increase in the outlet temperature of the refrigerator is reached.
