SEVERN磁导率计1.08 Mu产品介绍

低钼磁导率指示器用于测量不锈钢等弱磁性材料的磁导率。磁导率是对材料磁化能力的一种测量。

磁导率指示器用于测量不锈钢焊缝等材料的铁素体含量 用于核电站和食品处理设备中不锈钢管焊接的稳健性测量。铁氧体指示剂有两种校准方式:铁氧体 率和铁氧体数。

LOW MU PERMEABILITY INDICATOR Used to measure the magnetic permeability of weakly magnetic materials such as Stainless Steel. Permeability is a measure of a materials ability to be magnetized.

FERRITE INDICATOR Used to measure the Ferrite content of a material such as a Stainless Steel weld. It is used extensively to measure the soundness of welds to Stainless Steel pipes in nuclear power plants and food handling equipment. The Ferrite Indicator comes in two types of calibrations: Percent Ferrite and Ferrite Number.

磁导率指示器是一种简单、坚固、无损的检测仪器，用于实验室、车间和现场使用。GO、NO-GO特性允许对奥氏体不锈钢和锰钢基体和焊缝材料进行即时验收测试。该指标无需外部标准，无需调整，无需目视读数，不受位置影响。它在板材、板材、棒材、不规则形状的物体和复杂部件的单个部件上表现同样出色。它能有效定位异质产品的高渗透率或低渗透率区域，并适用于需要冷成形和退火操作的区域。

这个指示器重3盎司，长5英寸，便于手动操作。所有的金属部件都镀有明亮的镍。指示器和它的镶嵌件都装在一个漂亮的木制盒子里。该指标符合MIL-I-17214B更换规格SEV-ENG-96001。

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.

The Indicator weighs 3 oz. and is 5 inches long making it comfortable for hａnd held operations. All metal components are bright Nickel plated. The Indicator and it&＃39;s Inserts are furnished in a handsome wooden box. The Indicator conforms to SEV-ENG-96001, the replacement specification for MIL-I-17214B.
