SEVERN磁導(dǎo)率計介紹
低微量元素滲透率指示器是一種簡單，堅固，無損的檢測儀器，專為實驗室，車間和現(xiàn)場使用而開發(fā)。GO，NO-GO功能允許對奧氏體不銹鋼和錳鋼基體和焊接材料進行即時驗收測試。該指標(biāo)不需要任何外部標(biāo)準(zhǔn)，不需要任何調(diào)整，不需要任何視覺讀數(shù)，并且不受位置的影響。它在片材，板，棒，不規(guī)則形狀的物體以及復(fù)雜組件的單個零件上的性能同樣出色。它可以有效地定位異質(zhì)產(chǎn)品中的高滲透率或低滲透率區(qū)域，并可以用于需要冷成形和退火操作的場合。
The Low Mu Permeability Indicator is a simple, rugged, non-destructive inspection instrument developed for laboratory, shop and field use. The GO, NO-GO feature permits instant acceptance testing of austenitic stainless and Manganese steel base and weld materials. The Indicator requires no external standards, no adjustments, no visual readings and is unaffected by position. It performs equally well on sheets, plates, rods, irregular shaped objects and individual parts of complex components. It is effective in locating areas of high or low permeability in heterogeneous products and has application where cold forming and annealing operations are required.

SEVERN磁導(dǎo)率計使用說明
高靈敏度低微量元素滲透率指示器是一種易于操作的設(shè)備，用于指示低滲透率材料的相對滲透率。
指示器的操作基于用于校準(zhǔn)插入件和未知材料的永久磁鐵的相互吸引。在使用中，將插入件擰入殼體的頂部。然后通過取決于刀片的磁導(dǎo)率的力將磁體吸引到插入件上。從殼體底部的開口伸出的磁鐵末端然后與被測材料接觸。接觸面必須清潔且無氧化皮或異物，然后將指示劑沿垂直于接觸面的方向移開。如果被測材料的磁導(dǎo)率高于校準(zhǔn)插件的磁導(dǎo)率，則當(dāng)指示器移開時，磁鐵將與插件底部完全分離。當(dāng)固定磁鐵的金屬軸環(huán)撞擊塑料外殼的底部時，將發(fā)生完全分離。如果被測材料的磁導(dǎo)率低于插入值，則當(dāng)指示器移開時，磁鐵將首先與被測材料分離。因此，通過互換插入物，可以確定兩個插入物的值之間的材料的滲透性。該指標(biāo)并未確定材料滲透率的單一準(zhǔn)確值；它確定了滲透率范圍，每個刀片的公差極限在校準(zhǔn)證書的背面指定。
指標(biāo)的兩個功能值得特別提及。首先，附有磁鐵的平衡梁允許在所有位置使用指示器，而無需進行重力校正。其次，半球形磁體末端與插入件和測試材料提供點接觸。
The High Sensitivity Low-mu Permeability Indicator is a simple-to-operate device to be used for indicating the relative permeability of low permeability materials.
The operation of the Indicator is based on the mutual attraction of a permanent bar magnet for a calibrated insert and an unknown material. In use, an insert is screwed into the top of the case. The magnet is then atracted to the insert by a force dependent upon the insert's permeability. The end of the magnet projecting from the opening in the bottom of the case is then brought into contact with the material being tested. It is essential that the contact surface be clean and free from oxide scale or foreign material.The Indicator is then moved away in a direction perpendicular to the contact surface. If the material being tested has a higher permeability than that of the calibrated insert, then the magnet will completely separate from the bottom of the insert as the Indicator is moved away. A complete separation occurs when the metal collar holding the magnet strikes the bottom of the plastic case. If the permeability of the material being tested is lower than that of the insert value, the magnet will first separate from the test material as the Indicator is moved away. Thus, by interchanging the inserts, it is possible to determine the permeability of the material betweenthe values of two inserts. The Indicator does not determine a single exact value for the permeability of the material; it determines a permeability range, The tolerance limits for each insert is specified on the back of the Certificate of Calibration.
Two features of the Indicator deserve special mention. First, the balanced beam to which the magnet is attached permits the use of the Indicator in all positions without correction due to gravity. Secondly, the hemispherical magnet ends provide point contact with the inserts and the test materials.
