Description
(54) ЭЛЕКТРОМАГНИТНЫЙ ТОЛЩИНОМЕР(54) ELECTROMAGNETIC THICKNESS METER
Изобретение относитс к неразрушающему контролю, а именно к электромагнитны приборам измерени толщины покрытий иэделий .The invention relates to non-destructive testing, in particular to electromagnetic devices for measuring coating thickness of ide.
Известен толщиномер, содержащий преобразователь , измерительный и эталонный каналы, блок измерени разности сигналов обоих каналов 1,A thickness gauge is known, comprising a transducer, measuring and reference channels, a unit for measuring the difference of the signals of both channels 1,
Известный толщиномер обладает недостаточной точностью и сложностью настройки .Known thickness gauge has insufficient accuracy and complexity of setting.
Наиболее близким по технической сущности к изобретению вл етс электромагнитный толщиномер с амплитудно-фазовой обработкой сигнала, который комплектуетс образцами материала основы и покрыти 2.The closest in technical essence to the invention is an electromagnetic thickness gauge with amplitude-phase signal processing, which is completed with samples of the base material and coating 2.
Ор содержит генератор, блок обработки сигнала и трехобмоточный с ферромагнит ным сердечником преобразователь, одна обмотка которого (возбуждающа ) подключена к выходу генератора, а две других, включенные встречно (измерительные) ко входу блока обработки сигнала.The op contains a generator, a signal processing unit, and a three-winding converter with a ferromagnetic core, one winding of which (exciting) is connected to the generator output, and the other two connected counter-measuring (measuring) to the input of the signal processing unit.
Недостатком известного толщиномера вл етс использование эталонных образцов , которое удлин ет процесс настройки, повыщает себестоимость толщиномера и иэ-за быстрого износа мер толщины обладает невысокой точностью измерени .A disadvantage of the known thickness gauge is the use of reference samples, which lengthens the adjustment process, increases the cost price of the thickness gauge and, due to the rapid wear of the thickness measures, has a low measurement accuracy.
Цель изобретени - повышение точности измерени и снижение трудоемкости настройки толщиномера.The purpose of the invention is to improve the measurement accuracy and reduce the complexity of setting the thickness gauge.
Это достигаетс тем, что предлагаемый толщиномер снабжен блоком моделировани эталонов толщины, выполненным из последовательно соединенных между собой предварительного усилител , активного фазовращател , усилител напр жени и эмиттернного повторител , и переключателем, вход блока моделировани подключен к одной из измерительных обмоток преобразовател , а выход через переключатель ко входу блока обработки сигнала.This is achieved by the fact that the proposed thickness gauge is equipped with a simulation unit of thickness standards, made of a preamplifier connected in series, an active phase shifter, a voltage amplifier and an emitter follower, and a switch, the input of the modeling unit is connected to one of the measuring windings of the converter, and the output is through to the input of the signal processing unit.
На чертеже представлена блок-к;хема предлагаемого толщиномера.The drawing shows a block to; heme of the proposed thickness gauge.
