(54) УСТРОЙСТВО ДЛЯ ОПРЕДЕЛЕНИЯ КОЭФФИЦИЕПТЛ ЛИНЕЙНОГО РАСШИРЕНИЯ ПРОВОЛОЧНЫХ ОБРАЗЦОВ(54) DEVICE FOR DETERMINING THE COEFFECTILE OF LINEAR EXTENSION OF WIRE SAMPLES
1one
Изобретение относитс к измерительной технике и предназначено дл определени коэффициента линейного расширени проволоки и записи дилатометрических графиков , может быть использовано при разработке образцовых дилатометров, а также специальных дилатометров дл пластин, стержней, проволоки и т.п.The invention relates to a measurement technique and is intended to determine the linear expansion coefficient of a wire and record dilatometric graphs, can be used in the development of exemplary dilatometers, as well as special dilatometers for plates, rods, wires, etc.
Известно устройство дл автоматической записи дилатометрических графиков, содержащее дилатометр с дифференциальнотрансформаторным датчиком удлинени образца , включенным на вход регистрирующего прибора с дифференциально-трансформаторной схемой, и термопару, помещенную в зоне нагрева образца 1.A device for automatically recording dilatometric graphs is known, which contains a dilatometer with a differential transformer sensor for sample extension included at the input of a recording device with a differential transformer circuit, and a thermocouple located in the heating zone of sample 1.
Недостатки известного устройства состо т в низкой точности измерени из-за сложности конструкции, содержащей множество механических узлов и сопр жений, а также в низком быстродействии из-за больщой посто нной времени реверсивного двигател .The disadvantages of the known device are low measurement accuracy due to the complexity of the design, which contains many mechanical components and interfaces, as well as low speed due to the long time constant of the reversing engine.
Наиболее близким к предлагаемому по технической сущности вл етс устройство дл осуществлени определени коэффициента линейного расширени проволочныхClosest to the proposed technical entity is a device for carrying out the determination of the coefficient of linear expansion of wire
образцов путем разогрева их электрическим током и измерени параметров в нагретом и холодном состо ни х, содержащее корпус с закрепленны.ми на нем образцом проволоки , источником обогрева и датчиком температуры 2.samples by heating them with electric current and measuring the parameters in the heated and cold states, containing the case with a fixed wire sample, a heating source and a temperature sensor 2.
Недостатки устройства заключаютс в низкой точности измерени , так как измер емые падени напр жений между потенциальными отводами и потенциальными съемниками вл ютс величинами малыми, The drawbacks of the device are low measurement accuracy, since the measured voltage drops between potential taps and potential pullers are small values,
10 а также в трудно осуществл емом записывании дилатометрических графиков.10 as well as in difficult recording of dilatometric graphs.
Цель изобретени - повыщение точности измерени .The purpose of the invention is to increase the measurement accuracy.
