Description

Дл  регулировани  температуры печи, например, дл  плавки вакуумного стекла примен ют автоматическпе регул торы, содержащие в качестве датчика температуры термометр сопротивлени .To regulate the temperature of the furnace, for example, automatic regulators are used for melting vacuum glass, which contain a resistance thermometer as a temperature sensor.

Известпые регул торы не обеспечивают под,и,ержани  такой температуры нагреваемого в печи материала, .фи которой его электрическое сопротивление равно заданному.Known regulators do not provide under, and, keeping such a temperature of the material heated in the furnace, for which its electrical resistance is equal to the specified one.

Дл  устранени  указанного недостатка предлагаетс  использовать в качестве термометра сопротивлени  сам нагреваемый в печи материал , например стекло.To eliminate this drawback, it is proposed to use as the resistance thermometer itself a material heated in a furnace, for example glass.

На чертеже изображена принципиальна  схема предлагаемого регул тора .The drawing shows a schematic diagram of the proposed controller.

Регул тор состоит из мостовой схемы с сопротивлени ми 1, 2, 3 к 4, в которой одним из плеч служит образец исследуемого стекла.The regulator consists of a bridge circuit with resistances of 1, 2, 3 and 4, in which one of the arms is a sample of the investigated glass.

Напр жение разбаланса моста подаетс  на нуль-индикатор 5, который с помощью регул тора 6 управл ет работой нагревательного элемента 7 печи. Температура образца стекла, помещенного в печь, измер етс  с помощью потенциометра 8 с термопарой.The unbalance voltage of the bridge is applied to the null indicator 5, which by means of the controller 6 controls the operation of the heating element 7 of the furnace. The temperature of the sample glass placed in the furnace is measured using a thermocouple potentiometer 8.

Измерительный мост питаетс  посто нным током, периодически мен ющим направление, или переменным током пониженной частоты от соответствующего источника 9.The measuring bridge is powered by direct current, periodically changing direction, or alternating current of reduced frequency from the corresponding source 9.

Так как датчик схемы представл ет собой сопротивление исследуемого образца, то предлагаемый регул тор автоматически поддерживает температуру образца, соответствующую его заданному сопротивлению .Since the sensor circuit is the resistance of the sample, the proposed controller automatically maintains the sample temperature corresponding to its specified resistance.

Предлагаемый автоматический регул тор может быть применен и дл  расплавленного жидкого стекла.The proposed automatic regulator can also be used for molten liquid glass.
