Description
(5) УСТРОЙСТВО ДЛЯ КОНТРОЛЯ ТВЕРДОСТИ(5) DEVICE FOR CONTROL HARDNESS
II
Изобретение относитс к неразрушающему контролю и может быть использовано дл измерени твердости ферромагнитных изделий.The invention relates to non-destructive testing and can be used to measure the hardness of ferromagnetic products.
Известно устройство дл контрол твердости, содержащее преобразователь , два фильтра-усилител , амплитудный детектор, умножитель, фазовый детектор и индикатор П .A device for monitoring hardness is known, comprising a transducer, two filter amplifiers, an amplitude detector, a multiplier, a phase detector, and an indicator P.
Недостатком известного устройства вл етс низка точность и экономичность .A disadvantage of the known device is low accuracy and efficiency.
Наиболее близким к предлагаемому по технической сущности вл етс устройство дл контрол твердости, содержащее соединенные последовательно блокинг-генератор, преобразователь, селективный усилитель и выпр митель, и индикатор 2 .Closest to the proposed technical entity is a device for controlling hardness, containing a blocking generator, a converter, a selective amplifier and a rectifier, and an indicator 2 connected in series.
Недостатком данного устройства вл етс низка точность контрол , так как при измерени х не учитываетс химический состав контролируемого из .дели .The disadvantage of this device is low control accuracy, since the measurements do not take into account the chemical composition of the controlled part.
Цель изобретени - повышение точности контрол .The purpose of the invention is to improve the accuracy of control.
Поставленна цель достигаетс тем, что устройство снабжено соединенными последовательно измерителем электропроводности , измерительным мостом и аппроксиматором, второй вход которого подключен к выходу выпр мител , а выход соединен с индикатором.The goal is achieved by the fact that the device is equipped with a conductivity meter connected in series, a measuring bridge and an approximator, the second input of which is connected to the output of the rectifier and the output connected to the indicator.
На чертеже представлена блок-схема The drawing shows a block diagram
to устройства.to device.
-Устройство дл контрол твердости содержит соединенные последовательно блокинг-генератор 1, преобразователь 2 с намагничивающей и измерительной обмотками 3 и 4, селективный усилитель 5, выпр митель 6, аппроксиматор 7 и индикатор 8.The hardness control device contains a blocking generator 1 connected in series, a converter 2 with magnetizing and measuring windings 3 and 4, a selective amplifier 5, a rectifier 6, an approximator 7 and an indicator 8.
Ко второму входу аппроксиматора 7 подключены соединенные последователь20 но измеритель 9 электропроводности и измерительный мост 10.Connected in series to the second input of the approximator 7 are a conductivity meter 9 and a measuring bridge 10.
