Magnetic induction for determining ferrite content

Fischer Instrumentation has introduced the Feritescope range of electronic magnetic induction instruments for determining ferrite content in the laboratory and field.

In industrial applications, tanks and pipelines need to withstand high temperatures and pressures and often be resistant to harsh chemicals.

Steel needs to be tough, strong, corrosion and pitting resistant to avoid long term structural failure and each form of steel - austenitic, ferritic, duplex - has its own particular composition mix and subsequent attributes and drawbacks, making selection of an appropriate steel a complex decision.

In manufacture, steel is often heat-treated or welded which changes its crystalline structure.

It is critical that this is correctly balanced to prevent premature failure.

The ferrite content gives a valuable and accurate indication that the balance has been maintained.

Laboratories can determine the ferrite content and other characteristics of steels and many techniques, such as metallographic, x-ray defraction or magnetic induction, are available.

Magnetic induction is a simpler technique suited to both the laboratory and field.

Electronic magnetic induction instruments such as Fischer's Feritescope range provide a very practical solution.

These instruments are widely specified for on-site use on projects ranging from oil exploration, chemical production, utility and other processing plants exposed to heat, aggressive media and high pressure.
