Description
Переклкзчатели 3 и 5 св заны между собой так, что при включении одного выключаетс другой. Рабочий спай термопары 7 погружен в сосуд 8 с жидкостью.Switches 3 and 5 are interconnected so that when one is turned on, the other is turned off. The working junction of thermocouple 7 is immersed in the vessel 8 with the liquid.
Дл проведени контрол гальванометром 4 определ ют величину термо-эдс на концах компенсационных проводов термопары . Переключател ми 3 и 5 отключают г.альванометр и подключают к термопаре источник тока 6. Затем производ т обратное переключение и повторно измер ют величину термо-эдс. Если при повторном измерении величина термо-эдс не изменитс , то компенсационные провода присоединены верно, т. е, в соответствующей пол рности. Если при повторном измерении величина термоэдс изменитс , то компенсационные провода присоединены неверно, т. е, в несоответствующей пол рности.To conduct the control, the galvanometer 4 determines the value of the thermo-emf at the ends of the thermocouple compensation wires. Switches 3 and 5 turn off the alvanometer and connect the current source 6 to the thermocouple. Then reverse the switching and measure the thermo-emf again. If, during the repeated measurement, the value of the thermo-emf does not change, the compensation wires are connected correctly, i.e., in the corresponding polarity. If, during repeated measurement, the thermopower value changes, the compensation wires are incorrectly connected, i.e., in the wrong polarity.
Описанный способ позвол ет быстро и надежно производить контроль пол рности соединени компенсационных проводов с электродами термопары как на стадии изготовлени термоэлектрических термометров так и в процессе их монтажа.The described method makes it possible to quickly and reliably control the polarity of the connection of the compensation wires with the thermocouple electrodes both during the manufacture of thermoelectric thermometers and during their installation.
