Description
Изобретение относитс к физико химическим исследовани м и может быть применено,в частности,при производстве и эксплуатации дифференциальных сканирующих калориметров . Известно устройство, представл ющее собой программный регул тор, в котором дл линейного измерени параметра к автотрансформатору приспосабливают моторчик, который через редуктор двигает ползунок с установленной скоростью. Таким образом к обогревателю печи подаетс все возрастающее напр жение СО Наиболее близким к предлагаемому по технической сущности вл етс спо соб, реализуемый в устройстве дл из менени температуры, в котором приме нено программное устройство, в качестве которого служит диск ресхорда , задающего во времени по определе ному закону изменение потенциала питани на нагревателе, установленном на термозадающей оболочке, внутри которой размещен объект. Закон изме- , нени потенциала подбираетс таким, чтобы он соответствовал температурному сигналу датчика, подверженного линейному температурному изменению. В процессе работы система регулировани поддерживает вблизи нул разность между задаваемым (мен ющимс ) и управл емым сигналом от датчика. В этом случае датчик отслеживает заданный закон температурыС 2.3. Недостатки этого способа - сложность системы регулировани дл его реализации и трудность слежени за двум измен ющимис во времени параметрами , т.е. низка точность. Целью изобретени вл етс повышение точности линейного измерени температуры . Поставленна цель достигаетс тем, что объект размещают на тепловыравнивающем теле и поддерживают посто нной разность температур межThe invention relates to physicochemical studies and can be applied, in particular, in the manufacture and operation of differential scanning calorimeters. A device is known that is a software controller in which a motor is fitted to the autotransformer to linearly measure a parameter, which moves the slider at a set speed through a reducer. Thus, an ever-increasing voltage of the CO is supplied to the furnace heater. The closest to the proposed technical essence is the method implemented in the device for changing the temperature, in which the program device is used, which is the reschord disk that specifies in time According to the law, the change of the supply potential on the heater installed on the thermoconductive sheath inside which the object is placed. The law of change of potential is chosen so that it corresponds to the temperature signal of the sensor, subject to a linear temperature change. During operation, the control system maintains near zero the difference between the set (changing) and controlled signal from the sensor. In this case, the sensor monitors a given law of temperature 2.3. The disadvantages of this method are the complexity of the control system for its implementation and the difficulty of tracking two time-varying parameters, i.e. low accuracy. The aim of the invention is to improve the accuracy of linear temperature measurement. The goal is achieved by the fact that the object is placed on a heat-leveling body and maintain constant temperature difference between
