HKB—1型磁化率仪研制及计算机联机的实现

MODEL HKB-1 MAGNETIC SUSCEPTIBILITY METER AND CONNECTED WITH COMPUTER

本文介绍了一种新研制的磁化率仪,它可测定自然界中大多数物质(良导体除外)的初始磁化率,特别适合于岩石的磁化率及其各向异性(AMS)测量。仪器工作磁场300A/m,频率920Hz,样机总磁化率测量灵敏度达到 2×10^(-12)m^3,读数采用数字显示方式并具有自动锁定功能。与计算机的联机采用了标准EIARS-232C串行接口,因此具有良好的通用性。在软件的控制下,计算机可自动完成测量数据的采集、计算处理、座标转换以及成图或存贮等工作,AMS参数的测量效率得到很大提高。

This paper introduces an updated designed magnetic susceptibility meter which can be sued to measure initial susceptibility even other material (expcept good conductors) and anisotropy of magnetic susceptibility (AMS) of rocks. It's operation magnetic field is about 300 A/m and frequency is 920 Hz, The sensitivity of test instrument is better than 2× 10-12m3. It has digital presentation and function of automatical locking. The various computers can be connect to the instrument with RS-232C series interface, then the measuring data processing and diagram display of AMS are all automatized.
