Fischer Feritscope MP30 Eddy Current and Magnetic Induction Unit rental/hire

The FERITSCOPE MP30 measures according to the magnetic induction method. A magnetic field generated by a coil enters into interaction with the magnetic components of the specimen. The changes in the magnetic field induce a voltage proportional to the ferrite content in a second coil. This voltage is then evaluated. All magnetic components of the otherwise non-magnetic structure are recognized, that is, in addition to delta ferrite and other ferritic components transformation martensite is also recognized.Increasingly, the chemical and petrochemical industries use duplex steel, e.g., for the reactor made of high corrosion resistant duplex stainless steel shown above. A ferrite deficiency in the weld beam may lead to cracks under the influence of tension or vibration. However, when welding duplex steel, it is easy to bring the ferrite content in the welding area to unfavorable values, either because of unsuitable welding additives or through wrong heat application or removal. Only a measurement on site can ensure that the processing steps did not change the optimal ferrite content resulting in a decrease of the mechanical or corrosion resistant properties.
