SENIS® Magnetic Field Mappers measure magnetic field of permanent magnets and electromagnets by means of 3-axis Hall probes. SENIS Hall probes are calibrated at SENIS’ ISO17025:2017 accredited calibration lab.

Our innovative, smart probe connection technology allows an easy interchange of Hall and AMR probes, touch stylus and specialized probes, such as eddy-current probes for crack detection, sliding probes for in-contact measurements, probe arrays, etc.

SENIS' mapper software provides real-time and off-line analysis and visualisation of measured magnetic field data, it generates a 3D map of the magnetic field, counts number of poles, calculates pole width for multipole magnets and rotors, detects zero crossings, measures magnetic angle, angle error and field homogeneity, provides GOOD/BAD decisions, calculates dipole magnetic moment, detects cracks in magnets and in non-magnetized blanks and much more.

SENIS offers several Mappers and Mapping Systems:

General-purpose, high-end standard-size mapper MMS-1A-RS:125mm^3 scan volume, 0.1% measurement accuracy, very high positioning accuracy, for all magnet types and forms
General-purpose, high-end large-size mapper MMS-1X-RS: same as MMS-1A-RS, but for larger magnets/rotors, i.e. 500mm^3 scan volume
Mapper for cylindric-shaped magnets MMS-2A-ROT: 155mmx55mm scan volume, 1% measurement accuracy, high positioning accuracy, for rotors, ring, disc and segment magnets
Entry-level portable mapper M3D-2A-PORT: 100mm^3 scan volume, 1% measurement accuracy, moderate positioning accuracy
Defectoscopes for crack detection in laboratories and as production EOL test equipment
Special customized mappers, mapper integration in CMMs and Form Measurement Machines such as MAHR MMQ, AC Magnetic Field Mapper, Mapping of demagnetized parts, EMC tests and others
