Description

Известные электромагнитные приборы дл  .измерени  толщины лзделий .КЗ. немагнитных материалов, построенные на принципе определени  толщины по изменению магнитного потока, -при установке электромагнита на изделии, дают точные показани  при условии чистоты поверхности .Known electromagnetic devices for measuring the thickness of the products. KZ. non-magnetic materials, built on the principle of determining the thickness of the change in magnetic flux, when installing an electromagnet on the product, provide accurate readings provided the surface is clean.

Описываемый электромагнитный лрибор, . построенный на том же принципе действи , более широко применим, так как точность измерени  им толщины издели  меньще зависит от чистоты его позерхно:ти.Described electromagnetic device,. built on the same principle of action, it is more widely applicable, since the accuracy of measuring the thickness of a product by it depends less on its surface cleanliness.

Это достигаетс  тем, что электромагниту придана Н-образна  форма, а измерительные обмотки его включены в дифференциальную мостовую схему .посто нного тока.This is achieved by the fact that the electromagnet is H-shaped, and its measuring windings are included in a differential bridge circuit of direct current.

На чертеже показана принцип альна  электрическа  схема прибора.The drawing shows the principle of the electrical circuit of the device.

Прибор выполнен в виде Н-образного электромагнита / с из.ме;)ительными обмотками 2 и 5 и намагничивающей обмотхой 4. Измерительные обмотки включены в дифференциальную мостовую схему посто нного тока, включающую селеновые выпр мители 5 и 5, потенциометр 7, сопротивление 8 и микроамперметр 9- Питание намагничивающей обмотки производитс  через автотрангсформатор 10.The device is made in the form of an N-shaped electromagnet / with an izme;) power windings 2 and 5 and a magnetizing winding 4. The measuring windings are included in a differential bridge DC circuit including a selenium rectifier 5 and 5, a potentiometer 7, a resistance 8 and microammeter 9- The magnetizing winding is supplied through an auto-transformer 10.

Величина изменени  магнитного потока представл ет собой сумму величин изменени  потока, созданного замыканием полюсов электро.магнита ферромагнитной деталью, и потока, созданного ви.хревыми токами в зависимости от,толщины и электросопротивлени  металла, к которому подноситс  электромагнит.The magnitude of the change in the magnetic flux is the sum of the magnitudes of the change in the flux created by the shorting of the poles of an electromagnet with a ferromagnetic part, and the flux created by heat currents depending on the thickness and electrical resistance of the metal to which the electromagnet brings.

Поскольку величина магнитного потока пропорциональна толщине измер емого издели , щкала микроамперметра градуируетс  в линейных измерени х и непасредственно по ней отсчитываетс  толщина.Since the magnitude of the magnetic flux is proportional to the thickness of the product being measured, the microammeter meter scale is graduated in linear dimensions and the thickness is measured directly along it.

Прибор может быть ислользован дл  измерени  толщин стенок различных резервуаров, труб, днищИ-других изделий из цветных металлов.The device can be used to measure the wall thicknesses of various tanks, pipes, bottoms and other products made from non-ferrous metals.
