Thanks to the use of professional software such as 3D CAD / 3D FEM and our own production, Systron is able to design and manufacture complex, customer-specific shieldings. Two reference projects are presented below.
An analyser for the determination of mass change, which contains a precision balance, is considerably disturbed by external magnetic fields at Straumann in Basel. Measurements showed that extreme near-DC changes of up to 19 µT occur. The source was found to be tram power lines running parallel to the building.
Systron was commissioned to design and manufacture a shielding box for the device in order to reduce the magnetic field changes to significantly <1 µT.
Measurements after installation of the annealed Mu-metal shielding show that the near-DC fields could be reduced by a good 99% and thus to <200nT.
According to Straumann, thanks to the shielding box, the analyser can now be operated without interference.
In close cooperation with Hamilton, Systron developed and manufactured a two-part shield housing made of mu-metal around the linear motor of the MagPip pipetting channel. This to prevent interference between the channels.
The tight space conditions and the required tolerances presented a special design challenge. Furthermore, attention had to be paid to the fact that the enclosure could be assembled easily and quickly during production.

Download Software Edison – Low Frequency
The download link for the software will be sent to you by email. There are no costs and you do not enter into any contractual obligations. Without an active licence, the software is automatically operated in demo mode, which is unlimited in time. In demo mode, however, the simulations are not calculated correctly and projects cannot be saved. Otherwise the software is fully functional.
