Description

Из примен емых в промышленной практике приборов дл  измерени  вакуума (например, в конденсаинонных установках паровых турбин на электростанци х) наиболее надежным и точным прибором, дающим показани  в абсолютных единицах,  вл етс  ртутно-стекл нных баровакууметр . Он представл ет U-образпую трубку, запа нную с одного конца и занолненную ртутью.Of the vacuum measuring instruments used in industrial practice (for example, in condensinon steam turbine plants at power plants), the most reliable and accurate instrument that gives readings in absolute units is the mercury-glass barometer-vacuum meter. It is a U-tube, sealed at one end and filled with mercury.

Главным недостатком ртутно-стекл пного баровакууметра, как, впрочем, и всех других ртутно-стекл нных приборов (например, барометров , термометров и т. п.)  вл етс  трудность регистрации их показаний и отсутствие удобной дл  наблюдени  шкалы.The main disadvantage of mercury-glass barovacimeter, as well as all other mercury-glass devices (for example, barometers, thermometers, etc.) is the difficulty of recording their readings and the lack of a convenient scale for observation.

Предлагаема  электронно-след ща  систелга позвол ет регистрировать показани  ртутно-стекл нных приборов, a также снимать показани  по стрелочной шкале.The proposed electron-trace system allows recording the readings of mercury-glass instruments, as well as taking readings on the dial gauge.

В зависимости от глубины вакуума, ртуть / (см. чертеж) в баровакууметре перемещаетс  вместе с плавающнм в мениске ферритовым поплавком 2. На U-образную трубку надета свободно перемещающа с  индуктивна  катущка 3, состо ща  из двух секций. Движение ферритового юнлавка мен ет индуктивность секций катушки и.мостова  схем-а 4 выходит из баланса. Ток разбаланса подаетс  на усилитель 5 типа УЭ-219 (от электронного моста Э.1Г1-2()9), который, в свою очередь, приводит в действие реверсивный двигатель 6 типа РД-09. Под действием двигател  6 перемещаетс  стрелка (плн перо), a также катушка 3 датчика . Движение катушки 3 по стекл нной трубке / происходпт до lev пор, пока ферритовый поплавок 2 не окажетс  в среднем положеним между секци ми катушки 3 и не восстановитс  баланс моста.Depending on the depth of the vacuum, the mercury / (see drawing) in the barometer moves together with the ferrite float 2 floating in the meniscus 2. A two-section free-moving inductive roller 3 is put on the U-shaped tube. The movement of the ferrite ynavka changes the inductance of the coil sections and the bridge circuit-a 4 out of balance. The imbalance current is applied to the UE-219 type amplifier 5 (from the electronic bridge E.1G1-2 () 9), which, in turn, drives the RD-09 type reversing motor 6. Under the action of the engine 6, the arrow (plate feather) is moved, as well as the coil 3 of the sensor. The movement of the coil 3 along the glass tube / occurs until the lev pores until the ferrite float 2 is in the middle position between the sections of the coil 3 and the balance of the bridge is restored.
