Success Stories

“We are happy to have found a measuring System, which gives us the opportunity to make a statement about the quality of our rotors as well as to develop certain performance aspects and increase development potential.”

Mr. Christian Kienzler,
Quality Engineer Elektric/Hybridsystem Formel E,
Porsche AG

“Customers like our product for two reasons; the first one is that SENIS Mappers can measure all three components of magnetic field with unprecedented accuracy and repeatibiliy very close to the magnet surface and in small gaps. The second reason is that our mapper software is very user-friendly and offers different types of analysis, with different types of data visualisation.”

“Bomatec is not just a customer of SENIS, but our important technology and business partner over many years. By demanding very high performance, high quality and high stability that is required by their customers, Bomatec helped SENIS improving our magnetic field (MMS-1A-RS) and crack testing equipment (Defectscope) to fulfil the highest automotive industry standards.“
