Description
Portable degaussing generator 876.99-GDM
First, SAV FRANCE offers you portable degaussing generator with high-tech industrial demagnetizer . As a result, our group offers you a complete range of degaussing products. In summary, SAV FRANCE therefore offers you both standard and tailor-made solutions. To conclude with more than 25 years of experience, we have acquired a lot of knowledge in degaussing systems.
Therefore, we can offer you for all kind of demagnetization:
We use a low frequency method.
Pulse method for internal demagnetization
- The alternating magnetic field is briefly increased in the coil to a high amplitude and then reduced to zero
- Frequency, current, pulse shape and pulse duration are controlled by a power modul
- The pulse parameters are optimally set for the application
- This technology provides best results
Use :
The portable degaussing generator type GDM70 is designed for mobile use (mounted on wheels + handles) and easy use, without the presence of a SAV FRANCE specialist. Thanks to its innovative design and using the latest technologies (microprocessor), the generator sends powerful and high-precision magnetic fields into the cables in order to magnetize or demagnetize steel parts with high repeatability.

- Extension of magnetic field cables by coupling
Other coil systems:
- Tunnel demagnetizer 890.42F
- Special coils
Demagnetization:
- Low frequency sine wave pulse demagnetization with 1Hz for high penetration depth
- Progressive frequency sine wave pulse
- Pulse length between 1s and 30s, depending on needed application
- Setting of all relevant process parameters (amplitude, pulse duration, rate of field increase and decrease etc.)
- Further technological field control functions for special applications
Magnetization DC:
- Adjusting the polarity, amplitude and duration of the DC sequence
Magnetic symmetry:
- Adjustment of the residual magnetism in fluxing direction
Typical applications:
- NDT (MPI, ECT)
- Rotating equipment
- Mechanical engineering, tool manufacturing
- Steel industry, supply parts
- Welding
- R&D
This system is also used by our specialists for the demagnetization of parts on site or in our workshops.
Some examples of application:
- Demagnetization of automotive parts
- Demagnetization of aeronautical parts
- Demagnetization of tools
- Demagnetization of loose parts
