Description
Изобретение относитс к технике измерени и может быть использовано в агломерационном производстве дл измерени уровн ферромагнитного материсша в технологических емкост х .The invention relates to a measurement technique and can be used in sinter production to measure the level of ferromagnetic matter in process tanks.
Известны устройства измерени уровн магнитопроводных сред в технологических емкост х, в основу которых положен принцип шунтировани однополюсного круглого сечени магнитопровода с намотанными на него первичными и вторичными витками ферромагнитной средой..The devices for measuring the level of magnetic fluids in process capacitors are known, which are based on the principle of shunting a single-pole circular section of a magnetic conductor with a primary and secondary coils of ferromagnetic medium wound on it ..
При отсутствии материала в емкости магнитный поток рассеиваетс по длине магнитопровода и индуцируема ЭДС во вторичной обмотке имеет максимальное значение. При повышении урон н магнитный поток возбудител частично замыкаетс через измер емую среду, так как часть магнитопровода становитс зашунтированной средой, и ЭДС вторичной обмотки уменьшаетс .In the absence of material in the tank, the magnetic flux is scattered along the length of the magnetic circuit and the induced emf in the secondary winding has the maximum value. With increasing damage, the magnetic flux of the exciter is partially closed through the measured medium, as part of the magnetic circuit becomes a shunted medium, and the EMF of the secondary winding decreases.
Недостатками данного устройства вл етс его низка чувствительность , а также нелинейна зависимости ЭДС вторичной обмотки от положени уровн .The disadvantages of this device are its low sensitivity, as well as the non-linear dependence of the EMF of the secondary winding on the position of the level.
Наиболее близким к предлагаемому по технической сущности вл етс уст- ройство дл измерени уровн.ч ферромагнитных сред, содержащее разомкнутый магнитопровод у-образной форми, вдоль которого размещены первична и вторична обмотки, подключенные соответственно, к источнику возбуждени и к индикатору. При по влении Closest to the proposed technical entity is a device for measuring the level of ferromagnetic media, containing an open magnetic circuit of a y-shaped form, along which the primary and secondary windings are connected, respectively, to the excitation source and to the indicator. When appearing
10 материала у стенок чехла поток замыкаетс через магнитный материал и повышаетс взаимоиндуктивность между первичной и вторичной обмотками. Повышаетс ЭДС вторичной обмотки про5 порционально глубине погру);;ени датчика в измер емую среду 2.10 of the material at the walls of the cover, the flow is closed through the magnetic material and the mutual inductance between the primary and secondary windings increases. The EMF of the secondary winding increases in proportion to the depth of the load;); sensor enters the measured medium 2.
Недостатком известного устройства вл етс его низкие чувствительность и точность, обусловленные фор20 мой выполнени магнитопровода.A disadvantage of the known device is its low sensitivity and accuracy, due to the design of the magnetic circuit.
Це. ь изобретени - повышение чувствительности и точности измерени .Tse. l invention - improving the sensitivity and accuracy of measurement.
