Изобретение относитс  к области контактной термометрии.This invention relates to the field of contact thermometry.

Известны устройства дл  измерени  коэффициента термоэлектродвижущей силы материалов , содержащие исследуемую и измерительную термопары, гальванометр, делитель напр жени  и источник питани  к нему.Devices are known for measuring the coefficient of thermo-electromotive force of materials containing a thermocouple under test and measuring, a galvanometer, a voltage divider and a power source thereto.

Однако в известном устройстве раздельное и неодновременное уравновешивание термоэлектродвижущей силы исследуемой и измерительной термопар приводит к значительной погрешности измерени .However, in the known device, the separate and non-simultaneous balancing of the thermoelectromotive force of the thermometer and measuring thermocouple leads to a significant measurement error.

Цель изобретени  - повысить точность измерени .The purpose of the invention is to improve the measurement accuracy.

Дл  этого одна из термопар используетс  в качестве источника питани  делител  напр жени .For this, one of the thermocouples is used as a power source for a voltage divider.

На чертеже показана схема предлагаемого устройства, включающа  исследуемую термопару 1, измерительную термопару 2, сопротивлени  3 и 4 делител  напр жени  и гальванометр 5.The drawing shows a diagram of the proposed device, including the thermocouple 1 under test, the measuring thermocouple 2, the resistance 3 and 4 of the voltage divider and the galvanometer 5.

Устройство работает следующим образом.The device works as follows.

Гор чий спай измерительной термопарыHot junction measuring thermocouple

Привод т в тепловой контакт с гор чим спаем исследуемой термопары. Затем к общей точке делител  (сопротивлени  3) подключают холодные спаи термопар. Если известно, у которой нз термопар коэффициент термоэлектродвижущей силы больше, ее сразу подключают к полному сопротивлению делител . Установив значение одного из сопротивлений делител , например 3, уравновешивают схему изменением другого сопротивлени  делител  4. Значение коэффициента термоэлектродвижущей силы исследуемой термопары наход т расчетным путем.Thermal junction is brought into thermal contact with the thermocouple under study. Then, the cold junctions of thermocouples are connected to the common point of the divider (resistance 3). If it is known that the coefficient of thermoelectromotive force is greater in nz thermocouples, it is immediately connected to the impedance of the divider. Having established the value of one of the resistance of the divider, for example, 3, the circuit is balanced by changing the other resistance of divider 4. The value of the thermoelectromotive force coefficient of the thermocouple under study is found by calculation.
