New PFM08-30 MT installed

Posted byJames McKenziePosted inExciting updates

The first of generation 8 PFM has been installed at National Institute of Metrology (NIM), Beijing, PRC. This machine gives the capability to measure samples from -50 oC to over 200 oC with sample sizes from 5mm to 35mm. It was installed at the NIM Hepingli campus.

The PFM-08 range of magnet characterisation magnetometer can accurately measure the magnetic hysteresis loop and extract key values for all magnetic materials (particularly suited for high performance magnetic materials such as NdFeB, SmCo, AlNiCo and coated magnets). With a maximum field of 10.5T (8356 kA/m / 105 kOe) even the most coercive materials and highest grades of NdFeB magnets can be measured, while traditional permeameters cannot measure these high coercivity materials due to pole piece saturation limitations. The 8th generation of PFMs from Hirst uniquely feature the eddy current correction (patented F-2F algorithm), Self-Demagnetisation Field (SDF) correction function (to allow accurate measurement of a wide range of samples from cylinders, cuboids and arbitrary sample shapes), and Hirst proprietary Self De-magnetisation Field Function SDFF™ (patented) which accurately generates an open to closed circuit mapping (O2C™). The first generation of Hirst industrial PFM was launched in 1998 and the company won an Institute of Physics business award for the SDFF™ technology in 2020. HirstLab v2 software and Hirst proprietary SDFF™ technology has been implemented in collaboration with the National Institute of Metrology (NIM), Beijing, as part of a contract for the first PFM08-30 MT placed by NIM. v2 software and Hirst proprietary SDFF™ technology has been implemented in collaboration with the National Institute of Metrology (NIM), Beijing, as part of a contract for the first PFM08-30 MT placed by NIM.
